In recent years fiber optic cable is becoming apparent that fiber-optics are steadily replacing copper wire being an appropriate way of communication signal transmission. They span the long distances between local telephone systems as well as supplying the backbone for a lot of network systems. Other system users include cable tv services, university campuses, office buildings, industrial plants, and electric power companies.

There are three kinds of fiber optic cable widely used: single mode, multimode and plastic optical fiber (POF). Although fibers can be made from transparent plastic, glass, or perhaps a combination of the two, the fibers used in long-distance telecommunications applications will always be glass, because of the lower optical attenuation. Both multi-mode and single-mode fibers are utilized in communications, if you need to transmit less data over longer distances, use single mode fiber optic cables. For any greater data capacity over shorter distances, opt for multi mode fiber optic cables, with multi-mode fiber used mostly for brief distances (up to 500 m),Multi mode is usually employed for LANs and other small networks. And single-mode fiber used for longer distance links.

Single Mode Fiber: Single Path through the fiber

Single Mode cable is really a single stand (most applications use 2 fibers) of glass fiber with a diameter of 8.3 to 10 microns which has one mode of transmission. Single Mode Fiber having a relatively narrow diameter, by which only one mode will propagate typically 1310 or 1550nm. Carries higher bandwidth than multimode fiber, but needs a light source having a narrow spectral width. Single Mode can also be known as single-mode fiber, single-mode optical waveguide, mono-mode optical fiber and uni-mode fiber. Single-mode fiber provides you with better pay of transmission, it also can transport the signal up to 50 times farther distance than multimode, at a slightly more expensive.Single-mode fiber has a smaller core than multimode.

Single Mode fiber is used to connect long distance switches, central offices and SLCs (subscriber loop carriers, small switches in pedestals in subdivisions or office parks or in the basement of a larger building). Practically every telco's network has become fiber optics except the bond to the home.

Multi Mode Fiber: Multiple Paths through the fiber

Multi-Mode cable has a little bit bigger diameter, having a common diameters in the 50-to-100 micron range for the light carry component (in the US the most typical size is 62.5um).Typical multimode fiber core diameters are 50, 62.5, and 100 micrometers. Multi Mode fiber can be used for shorter distances. Most applications by which Multi-mode fiber is used, 2 fibers are utilized. Multimode fiber gives you high bandwidth at high speeds (10 to 100MBS - Gigabit to 275m to 2km) over medium distances. Light waves are dispersed into numerous paths, or modes, because they traverse the cable's core typically 850 or 1300nm. Long cable runs (Above 3000 feet 914.4 meters in length), the multiple paths of sunshine are believed to result in signal distortion at the receiving end, resulting in lost packets and incomplete data transmission. IPS stands out on the use of single mode fiber in most applications using Gigabit and higher bandwidth.

:: A Small History of LC Connectors

The LC connector was a evolutionary approach to experiencing this goals of SFF (Small Form Factor) connector. The LC connector utilizes the traditional aspects of a SC duplex connector having independent ceramic ferrules and housings with the overall size scaled down by one half.

The LC family of connectors includes a stand-alone simplex design, a behind-the-wall (BTW) connector, and also the duplex connector available in both single mode and multimode tolerances, all designed while using RJ-style latch.

The LC connector is a universal connector. It is available in simplex and duplex configurations and is half how big the SC and utilizes a 1.25mm ferule. The LC is highly favored for single mode and is easily terminated with an adhesive. TheyˇŻre actively replacing the SC connectors in corporate environments due to their smaller size.

:: The Most Critical Parameters You Should Be Looking

Many manufacturers make LC optic fiber patch cables, but they are not all created equal. Here are the most critical optical performance parameters you should be looking closely. This fiber optic cable manufacturer provide the detail fiber optic cable specifications, you can reference its specs.

A) Single mode LC optic fiber patch cables

Single mode LC patch cords is available in several polishing favors: PC, UPC and APC.

a) PC means Physical Contact.

This is the most basic polishing. The back reflection is not too good, especially for just one mode fiber system. The rear reflection is under -45dB. Since single mode fiber systems are particularly sensitive to back reflections, we don't recommend using PC polish. It is best to choose a UPC polish for single mode LC fibers.

b) UPC stands for Ultra Physical Contact.

It supplies a better back reflection performance: under -50dB. While not providing the superior optical return loss performance of the APC connector - UPC connector has return loss (back reflection) characteristics that are appropriate for intraplant serial video or data transmissions.

c) APC means Angled Physical Contact.

The endface is polished precisely in an 8-degree angle to the fiber cladding to ensure that most return loss is reflected into the cladding where it can't hinder the transmitted signal or damage the laser source.

As an effect, APC connectors offer a superior RL performance of -65 dB. APC LC optic fiber patch cables are best for high bandwidth applications and long haul links because it provides the lowest return loss (RL) characteristics of connectors now available.

However, it is extremely hard to terminate an LC APC connector at 8 degrees with any consistent degree of success within the field.

B) Multimode LC fiber patch cables

Multimode LC optic fiber patch cords have only one sort of polishing: PC (Physical Contact) polishing.

However, there are at least three kinds of common multimode fibers to select from. 62.5/125um multimode fiber (also called OM1), 50/125um multimode fiber (also known as OM2), and 10Gig laser optimized 50/125um multimode fiber (also known as OM3 multimode fiber OR OM4 multimode fiber ).

Among multimode LC fiber patch cables, usually you only care about the insertion loss which needs to be no more than 0.3 to 0.5dB.

:: Which kind of LC Patch Cords Do you want?

LC fiber patch cables are available in a variety of configurations, such as LC to FC, LC to ST, LC to SC, LC to LC, LC to MTRJ, and many more. LC fibers can be found in simplex fiber cable and duplex fiber cable configurations.

Many types of fiber optic cable in the online company supply.It has many choices in the internet.How to choose the right fiber optic cables if you needed? Such as the OM3 multimode fiber OR OM4 multimode fiber.The first we must know fiber optic cable specifications,and know their different,and finally to determine which one is the most suitable.

10G Ethernet:

The 10G Ethernet basic power budget is about 6dB but this is degraded for longer link lengths due to signal distortions such as modal dispersion. These distortions mean that the detector requires more power to operate. The way this extra power is accommodated in channel planning is through a "power penalty". In our example, the power penalty increases from 0 to almost 5dB for the maximum channel length. The penalty is not linear and increases dramatically as the maximum length is reached. In designing the channel, a key factor is the power budget available for connection loss. This is the total power budget inclusive of penalties reduced by the cable attenuation, leaving that portion of the power budget that may be used to cover connector insertion loss, splice loss, bend loss and contamination.The table opposite shows that at 300m with OM3 the loss available for all connections is only 1.79dB. On the other end OM4 allows up to 4.55dB, an increase of 2.76dB. A typical data centre channel may have eight connections. For OM3, the average loss must be less than 0.24dB,including all factors which means premium terminations must be used and there is no margin for installation faults, pinched cables or any other channel problem With a budget of 0.57dB per connection, OM4 allows considerable headroom to support a stable network. Know more OM3 and OM4 in this blog ,it can help you to choose the best cable in your project.

OM3 multimode fiber
:

OM3 10G fiber optic cables which are used for 10Gigabit Ethernet applications. These cables are also called multimode OM3 10G Aqua fiber optic cables. Our OM3 10G cables are various types including different connector types, cable structure and cable length. Our OM3 multimode fiber that are compliant to ISO/IEC 11801 standards. These cables are used for 10Gbps networks to meet the requirement of continuous growing of high data rates.Typically 10 Gigabit applications are run on 9/125 Single Mode fiber, which require costly single mode transceivers. By utilizing the FOB501B series cables, you can implement low cost multimode transceivers or VCSEL's (Vertical Cavity Surface Emitting Lasers) resulting in greater overall system cost savings.

OM4 multimode fiber:

OM4 is the latest high modal bandwidth high performance 50/125 Graded Index Multimode (GIMM) cabled fibre specification. OM4 fibre enables extended range performance over high bit rate links such as 8 Gigabit Fibre Channel and 10 Gigabit Ethernet compared to existing fibre types. FiberStore offer a wide range of OM4 compliant cable assembly products in both standard OM4 and Reduced Bend Sensitivity (RBS) OM4 variants.

What is the difference between OM3 and OM4 fiber?

First, OM stands for optical multi-mode. Both OM3 an OM4 are 50/125 core fiber but they have different internal construction that allows the OM4 fiber to provide the same performance as OM3 but for longer distances. The reason for this is the difference in bandwidth, OM3 has 2500 megahertz bandwidth , OM4 has 4700 megahertz bandwidth. What this translates to is longer transmission distances for the OM4 fiber. So you will need to know the distance of the fiber run in order to help decide which kind of fiber and fiber accessories need to be used.

Fiber optic cables are the medium of choice in telecommunications infrastructure, enabling the transmission of high-speed voice, video, and data traffic in enterprise and service provider networks. Depending on the type of application and the reach to be achieved, various types of fiber may be considered and deployed, such as single mode duplex fiber and multimode duplex fiber optic cable.

Fibers come in several different configurations, each ideally suited to a different use or application. Early fiber designs that are still used today include single-mode and multimode fiber. Since Bell Laboratories invented the concept of application-specific fibers in the mid-1990s, fiber designs for specific network applications have been introduced. These new fiber designs - used primarily for the transmission of communication signals - include Non-Zero Dispersion Fiber (NZDF), Zero Water Peak Fiber (ZWPF), 10-Gbps laser optimized multimode fiber (OM3 fiber optic cable), and fibers designed specifically for submarine applications. Specialty fiber designs, such as dispersion compensating fibers and erbium doped fibers, perform functions that complement the transmission fibers. The differences among the different transmission fiber types result in variations in the range and the number of different wavelengths or channels at which the light is transmitted or received, the distances those signals can travel without being regenerated or amplified, and the speeds at which those signals can travel.

There are two different types of fiber optic cable: multimode and single-mode(MMF and SMF). Both are used in a broad range of telecommunications and data networking applications. These fiber types have dominated the commercial fiber market since the 1970's. The distinguishing difference, and the basis for the naming of the fibers, is in the number of modes allowed to propagate in the core of a fiber. The "mode" is an allowable path for the light to travel down a fiber. A multimode fiber allows many light propagation paths, while a single-mode fiber allows only one light path.

In multimode fiber, the time it takes for light to travel through a fiber is different for each mode resulting in a spreading of the pulse at the output of the fiber referred to as intermodal dispersion. The difference in the time delay between the modes is called Differential Mode Delay (DMD). Intermodal dispersion limits multimode fiber bandwidth. This is significant because a fiber's bandwidth determines its information carrying capacity, i.e., how far a transmission system can operate at a specified bit error rate.

The optical fiber guides the light launched into the fiber core (Figure 1). The cladding is a layer of material that surrounds the core. The cladding is designed so that the light launched into the core is contained in the core. When the light launched into the core strikes the cladding, the light is reflected from the core-to-cladding interface. The condition of total internal reflection (when all of the light launched into the core remains in the core) is a function of both the angle at which the light strikes the core-to-cladding interface and the index of refraction of the materials. The index of refraction (n) is a dimensionless number that characterizes the speed of light in a specific media relative to the speed of light in a vacuum. To confine light within the core of an optical fiber, the index of refraction for the cladding (n1) must be less than the index of refraction for the core (n2).

Fibers are classified in part by their core and cladding dimensions. Single mode duplex fiber have a much smaller core diameter than multimode duplex fiber optic cable. However, the Mode Field Diameter (MFD) rather than the core diameter is used in single-mode fiber specifications. The MFD describes the distribution of the optical power in the fiber by providing an "equivalent" diameter, sometimes referred to as the spot size. The MFD is always larger than the core diameter with nominal values ranging between 8-10 microns, while single-mode fiber core diameters are approximately 8 microns or less. Unlike single-mode fiber, multimode fiber is usually referred to by its core and cladding diameters. For example, fiber with a core of 62.5 microns and a cladding diameter of 125 microns is referred to as a 62.5/125 micron fiber. Popular multimode product offerings have core diameters of 50 microns or 62.5 microns with a cladding diameter of 125 microns. Single-mode fibers also have 125 micron cladding diameters.

A single-mode fiber, having a single propagation mode and therefore no intermodal dispersion, has higher bandwidth than multimode fiber. This allows for higher data rates over much longer distances than achievable with multimode fiber. Consequently, long haul telecommunications applications only use single-mode fiber, and it is deployed in nearly all metropolitan and regional configurations. Long distance carriers, local Bells, and government agencies transmit traffic over single-mode fiber laid beneath city streets, under rural cornfields, and strung from telephone poles. Although single mode duplex fiber has higher bandwidth, multimode fiber supports high data rates at short distances. The smaller core diameter of single mode duplex fiber also increases the difficulty in coupling sufficient optical power into the fiber. Relaxed tolerances on optical coupling requirements afforded by multimode fiber enable the use of transmitter packaging tolerances that are less precise, thereby allowing lower cost transceivers or lasers. As a result, multimode duplex fiber optic cable has dominated in shorter distance and cost sensitive LAN applications.

The Internet, telephone calls, and cable television all transmit information that can pass through fiber optic cables. Imagine having all this information at lightning-fast speed with less signal disturbances. The mechanics that lie beneath the ingenious work of fiber optic cables rests simply with the fact that light travels faster than electricity with fewer disturbances. The end result? Fiber optic cables provide a quicker and clearer transmission of data. Designed for optimal performance, our fiber optic cables allow you to enjoy the best quality technological experiences possible.

Now,many fibre optic cable suppliers provide a full range of bulk fiber optic cable. Including om3 fiber optic cable,om4 multimode fiber,armored fiber cable,simplex fiber optic cable,multimode duplex fiber optic cable and so on.Today, I will recommended the OM3 fiber optic cable in this blog.Know more OM3 fiber optic cable info and how to choose it.

OM3 10G fiber optic cables which are used for 10Gigabit Ethernet applications. These cables are also called multimode OM3 10G Aqua fiber optic cables. Our OM3 10G cables are various types including different connector types, cable structure and cable length. Our OM3 multimode fiber that are compliant to ISO/IEC 11801 standards. These cables are used for 10Gbps networks to meet the requirement of continuous growing of high data rates.

Big quantity information is generated every day on the internet and people need to exchange more and more information which in turn result in the demand of more and more bandwidth. IEEE802.3ae defined the 10Gigabit Ethernet standards used in LANs. OM3 10G multimode fiber optic cables are developed for such 10Gig Ethernet applications, they are with so called OM3 optical fiber, which is 50/125 type and with industrial acknowledged Aqua color. In FiberStore,we supply the OM3 cable standard color is aqua, but we also supply the customized color service,such as black, blue, orange, green, brown, slate, white, red, yellow, purple, rose, aqua or custom specified. We provide many types of OM3 products, including various kinds of OM3 fiber cable assemblies with various connectors like SC, ST , FC, LC, MTRJ, etc.

OTHER INFO: Which optical fiber should I choose, 50 micron or 62.5 micron?

Although 62.5 micron fiber was the most popular only a few years ago, 50 micron quickly gained market share and is continuing to do so. 50 micron fiber can have up to 20 times the bandwidth (data throughput capacity) of 62.5 micron. For identification purposes, multimode fiber, and also singlemode fiber, is often referred to by its performance level identified by ISO/IEC (International Organization of Standards and International Electrotechnical Committee), which is based on the fibers bandwidth capabilities. 62.5 micron multimode is referred to as OM1. 50 micron fiber is referred to as OM2, OM3 and the recently added OM4. As you would imagine, OM4 has greater bandwidth than OM3 and OM3 has greater bandwidth than OM2.

Fifty micron OM3 fiber is designed to accommodate 10 Gigabit Ethernet up to 300 meters, and OM4 can accommodate it up to 550 meters. Therefore, many users are now choosing OM3 and OM4 over the other glass types. In fact, nearly 80% of 50 micron fiber sold is OM3 or OM4.

If you require higher data rates or plan on upgrading your network in the near future, laser optimized 50 micron (OM3 or OM4) would be the logical choice.

We also supply 10Gig multimode fiber optic cables with various optional structures,such as om3 multimode fiber,om4 multimode fiber,multimode duplex fiber optic cable and so on. Our fiber optic cables are manufactured according to industrial standards and they feature the good price and reliable quality.Per foot price of each fiber cable is flexible depending on the quantities of your order, making your cost of large order unexpected lower.

Duplex Fiber Cable

Duplex fiber cable is designed for general fiber patch cord production where consistency and uniformity are vital for fast, efficient terminations. We have the right duplex fiber cable in many different outside diameter (OD) sizes and meet all tooling and termination requirements.Duplex Fiber Optic Cables consist of two fibers joined by a thin connection between the two jackets. Workstations, fiber switches and servers, fiber optic modems, and similar hardware require duplex cable. They are used in applications where data needs to be transferred bi-directionally. One fiber transmits data one direction; the other fiber transmits data in the opposite direction. Duplex fiber optic cables from FiberStore can be available in single-mode and multimode.

Multimode vs Singlemode Fiber

A "mode" in Fiber Optic cable refers to the path in which light travels. Multimode cables have a larger core diameter than that of singlemode cables. This larger core diameter allows multiple pathways and several wavelengths of light to be transmitted. Singlemode Duplex cables and Singlemode Simplex cables have a smaller core diameter and only allow a single wavelength and pathway for light to travel. Multimode fiber is commonly used in patch cable applications such as fiber to the desktop or patch panel to equipment. Multimode fiber is available in two sizes, 50 micron and 62.5 micron. Singlemode fiber is typically used in network connections over long lengths and is available in a core diameter of 9 microns (8.3 microns to be exact). Many types of multimode fiber optic cable (such as om3 multimode fiber) and singlemode fiber optic cable for sale in FiberStore.

How Fiber Optic Cables Work

The traditional method of data transmission over copper cables is accomplished by transmitting electrons over a copper conductor. Fiber Optic cables transmit a digital signal via pulses of light through a very thin strand of glass. Fiber strands (the core of the fiber optic cable) are extremely thin, no thicker than a human hair. The core is surrounded by a cladding which reflects the light back into the core and eliminates light from escaping the cable.

A fiber optic chain works in the following manner. At the one end, the fiber cable is connected to a transmitter. The transmitter converts electronic pulses into light pulses and sends the optical signal through the fiber cable. At the other end, the fiber cable is plugged into a receiver which decodes the optical signal back into digital pulses.

Advantages & Disadvantages of Fiber Optic Cable

There are many advantages and disadvantages in using fiber optic cable instead of copper cable. One advantage is that fiber cables support longer cable runs than copper. In addition, data is transmitted at greater speeds and higher bandwidths than over copper cables.
The major disadvantages of fiber optic cables are cost and durability. Fiber cables are more expensive than copper cables and much more delicate.

Three Steps To Pick Out A Fiber Optic Cable
So when you go to pick out a fiber optic cable, there are a few things you'll want to know. First, make sure that the type of connector you purchase matches your input connection. Second, check to see if your device prefers single or multi-mode transfer. Figure out if you need simplex fiber optic cable or duplex fiber optic cable. And finally, choose which length you need. You can discern this by setting up your system and running a string from the speaker or TV to the equipment. Always buy the next larger length rather than one that is on the small side. You won't regret it!

OM stands for optical multi-mode. Multi-mode optical fiber is a type of optical fiber mostly used for communication over short distances, for example within a building or on the campus. Multi-mode fibers are described using a system of classification determined by the ISO 11801 standard as OM1, OM2, and OM3, that is based on the modal bandwidth of the multi-mode fiber. Here are the meanings of these: 62.5/125um multimode fiber (OM1), 50/125um multimode fiber (OM2), and laser optimized 50/125um multimode fiber (OM3). This information is mainly about OM3, the short for OM3 fiber patch cable.

Laser Optimized Multimode Fiber (OM3) has been around since 1999. It supports 300-meter link lengths for 10 Gb/s applications and it is tested to make sure a 2,000 MHz-km Effective Modal Bandwidth (EMB). Its industry-standard 50um core size couples sufficient power from LED sources to aid legacy applications like Ethernet, Token Ring, FDDI, and Fast Ethernet for almost all in-building networks and most campus networks. The 50um core dimensions are also directly suitable for laser-based applications like Gigabit Ethernet and Fibre Channel, etc. Furthermore, it's the recommended multimode fiber type in ANSI/EIA/TIA-942, Telecommunications Infrastructure Standard for Data Centers.

OM3 fiber is a logical and cost-effective choice for short-range applications that require to aid 1Gb/s or multi-gigabit speeds, particularly when the cabling component costs take into account under 3 % from the total spend. When compared to total installation price of networks using lower bandwidth OM1 or OM2 fibers, the premium for OM3 fiber is usually about one percent but can provide significant cost savings for the electronics when upgrading to raised speeds, e.g. 10 Gb/s. 10G OM3 Duplex fiber optic patch cord cable includes two fibers, usually in a zip cord (side-by-side) style. We use duplex multimode or single mode fiber optic cable for applications that require simultaneous, bi-directional bandwith. Workstations, fiber switches and servers, fiber modems, and other alike hardware require duplex cable. 10G fiber optic patch cables provide 10 gigabit bandwith speeds in high bandwidth applications Five times faster than standard 50um fiber cable. They use both VCSEL laser and LED sources.

FiberStore has all lengths and connectors available. Duplex or simplex 10G fiber optic patch cables can be found at good price and fast shipping, for example, 50/125 sc-sc duplex OM3. And there is a different type of OM3 fiber patch cable called MPO. The MPO cable is designs for Data Center Applications. It's a round cable with the outer diameter of three,0 mm or 4,5 mm. The connectors where this cable is terminated on is known as MPO/MTP connector. To take a look, please click this link, 10G OM3 MPO Fiber Optic Cable.

Today 1Gb/s-ready backbone solutions would be the norm and provide 10x speed capability at almost cost parity of 100 Mb/s LED-based systems. OM3 fiber includes a significantly higher bandwidth advantage for longer reach 1 Gb/s and 10 Gb/s applications that many customers uses today or perhaps in the long run, while preserving the reduced system cost advantages of multimode fiber.

In addition, OM3 fiber shares the same connector technologies and installation techniques as 62.5um fiber, meaning installers can leverage their existing fiber installation experience without additional training. All this, coupled with the fact that greatly improved cabling materials and procedures have made 50um fiber cable-friendly, is driving the migration to OM3 because the multimode fiber of preference in LANs, SANs, data center interconnects and, now, Access applications.
