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.

As we all know that time is money, so save time is to cut cost. Exactly how should we save the time? The reply is to improve the speed. Fast internet speed, is exactly what I am going to talk about today.

Nowadays businesses are almost symbolic of fast internet speed. Your company is not heading anywhere if you're working using the old bandwidths that practically take days to transfer information from one server to a different. Well if you are an entrepreneur who's still stuck within the ancient internet days, you have to upgrade towards the Fiber Optics Internet that is currently taking over the planet. With fiber optics you're guaranteed fast internet speeds and faster, efficient communication with your clients.

You have to upgrade to fiber optics if you're still using the digital subscriber lines (DSL) internet, which uses copper lines to transfer data directly to people in residential houses. When using DSL, the internet speeds range from about 1.5 Mbps to six Mbps which is downstream speed. Upstream speeds with DSL are dismal at only 640 Kbps max. A DSL modem needs to be used to get the service up and running.

Compared to DSL internet, Fiber Optics Internet gives you another world of communication. With fiber optics, you receive the chance to transmit video, voice and internet data all at the same time. Rather than electricity, Fiber Optics Internet uses modulated light along with only one strand of optical fiber. This gives it a really clear advantage that DSL won't ever have regarding this; it never suffers inhibitions brought about by interferences of the electrical nature. This ensures that your internet is always ready to go keeping your business at the top. The bandwidth you receive from optical fiber is really a far cry from the disappointing speeds of DSL yet others enjoy it. You receive up to 40 Mbps for downstreams along with a good 5 Mbps upstream. This means better speeds and ability to deliver data to longer distances. Because of so many activities like watching movies now being carried out on the internet, this higher bandwidth could be the more the better. Audio and videos reception in your devices are also going to get better due to this.

Moreover, unlike copper wires, fiber optic cables don't transmit electrons and therefore aren't subjected to interference. Tapping into such a system without having to be detected is nearly impossible. This is the main reason why banking institutions try to use this technology for those their connectivity needs. These cables are also not affected by and EMI or electro-magnetic interference that might be caused because of other device around the cable. EMI can not only leak data but also can create noise in the signal. When information being sent around the world is looked at, this noise will multiply several times and may disrupt our reception. With fiber optics comes an association that is both secure and reliable.

Fiber Optics Internet clearly is better than the older types of internet. However, before you upgrade to fiber optics you must fully comprehend what the implications for your business are and what both you and your business are in position to gain by investing in fiber optics. First and fore most may be the ever mounting pressure that companies are facing to obtain faster internet and also to be able to transfer information faster than normal. Secondly, Fiber Optics Internet enables faster uploading of information which is necessary for almost all businesses today.

FiberStore is one of the major fiber optic cable manufacturers who supplies cables including corning optical cable, tight buffered fiber cable, fiber optics patch cords and so on.

In the telecommunications industry today, how to install the fiber optics that each optical engineer must learn in their work. Don't froget, when you install the fiber optics, you have to testing your fiber optic system. Optical-fiber tests are one of the final and many important procedures in installing optical networks.

How to set up the fiber optic cable?

Fiber optic cable may be installed indoors or outdoors using several different installation processes. Outdoor cable might be direct buried, pulled or blown into conduit or innerduct, or installed aerially between poles. Indoor cables could be installed in raceways, cable trays,put into hangers, pulled into conduit or innerduct or blown though special ducts with compressed gas. Cellular phone process will depend on the nature of the installation and also the kind of cable being used. Installation methods for both wire and optical fiber communications cables are similar. Fiber cable is designed to be pulled with much greater force than copper wire if pulled correctly, but excess stress may harm the fibers, potentially causing eventual failure.

The install fiber optic cable tips:

a) Stick to the cable manufacturer's recommendations. Fiber optic cable is often custom-designed for that installation and the manufacturer might have specific instructions on its installation.

b) Check the cable length to make sure the cable being pulled is long enough for that go to prevent needing to splice fiber and provide special protection for the splices.

c) Attempt to complete the installation in a single pull. Just before any installation, assess the route carefully to look for the ways of installation and obstacles likely to be encountered.

Testing fiber optic cables steps:

After installation, test each fiber in most fiber optic cables for verification of proper installation. Carry out the following tests:

a) Continuity testing to find out that the fiber routing and/or polarization is correct and documentation is proper.

b) End-to-end insertion loss utilizing an OLTS power meter and source. Test multimode cables by using TIA/EIA 526-14 Method B, and single-mode cables using TIA/EIA 526-7 (single-mode). Total loss shall be under the calculated maximum loss for the cable based on appropriate standards or customer specifications.

c) Optional OTDR testing may be used to verify cable installation and splice performance. However, OTDR testing shall not be accustomed to determine cable loss.

d) If the design documentation does not include cable plant length, which is not recorded during installation, test the length of the fiber using the length feature on an OTDR, or some OLTSs.

e) If testing shows variances from expected losses troubleshoot the issues and proper them.

FiberStore is really a professional fiber optic cable manufacturer of wide range of fiber optic and copper data communication cabling and connectivity solutions primarily for that enterprise market, offering an integrated suite of top quality, warranted products which operate as a system solutions for seamless integrate with other providers' offerings.

Over the past few years, fiber optic cable has become more affordable and widely used. Fiber is ideal for high data-rate systems such as FDDI, multimedia, ATM, or any other network that requires the transfer of large, time-consuming data files. And the basic cables are multimode optic cables and single mode cables.

A Comparison Of Multimode Cables And Single Mode Cables

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).

Most building cables had 62.5/125 micron multimode fibers for LANs or security systems, while outside plant cables were all single-mode fiber. For some time, we have been encouraging people to install hybrid cables with both multimode fibers for today and single-mode fibers for the future regardless of the fiber optic cable price.

If you are transmitting from a smaller fiber core to a larger one, it is not a problem since the larger fiber like large core optical fiber will collect all the light from the smaller one with minimal loss. But if you transmit light from a larger fiber to a smaller one, the light in the larger core will overfill the smaller core and large losses will occur. How big are the losses we are talking about? Coupling a multimode fiber to a single-mode fiber will cause about 20 dB loss. Connecting a 62.5 fiber to a 50 micron core fiber will cause 2 to 4 dB loss, depending on the type of source (laser or LED). In any case, it can be enough loss to prevent network equipment from working properly.

Both 50 micron and 62.5 micron multimode fibers have the same cladding diameter and can use the same connectors and termination processes, but testing still requires using the correct matching fiber optics patch cords or the measured loss will be too low by a few tenths of a dB in one direction (50 to 62.5), or 2 to 4 dB too high the other way (62.5 to 50.)

Needless to say, these mismatched fiber losses affect the end user the same way they affect the installer, creating excess connection loss that can cause systems to malfunction or have high error rates, causing an expensive and annoying service call. Unfortunately, there is no optical mating adapter that will match two dissimilar fibersalthough it has been tried many times. There is no solution other than preventing mismatched fiber terminations.

From data and voice to security and videoconferencing, a lot of today's IT infrastructure services depend on fiber optics to transmit information faster, farther, as well as in greater amounts than in the past. So fiber optics are more and more popularity within our internet. This post will attempt to reply to a few of the questions about fiber optic cable.

What is fiber optic cable?

A fiber optic cable is really a network cable which contains strands of glass fibers in a insulated casing. These cables are equipped for long distance and very high bandwidth (gigabit speed) network communications. If you want to know more info about fiber optic cable specifications, you can visit the FiberStore "Fiber Optic Cable Tutorial" within our tutorial.

There are a couple of types of optical fiber cables, Single-mode VS Multimode?

Single-mode fiber provides you with a greater transmission rate and as much as 50 times more distance than multimode, it is more expensive. Single-mode fiber includes a smaller core than multimode fiber-typically Five to ten microns. Merely a single lightwave can be transmitted at a with time. The small core and single lightwave virtually eliminate any distortion that may derive from overlapping light pulses, providing the least signal attenuation and also the highest transmission speeds associated with a fiber cable type.

Multimode fiber gives you high bandwidth at high speeds over long distances. Lightwave are dispersed into numerous paths, or modes, because they travel through the cable's core. Typical multimode fiber core diameters are 50, 62.5, and 100 micrometers. However, in long cable runs (greater than 3000 feet (914.4 ml), multiple paths of light can cause signal distortion at the receiving end, leading to an unclear and incomplete data transmission. For example, you can test to check the single mode duplex fiber vs multimode duplex fiber optic cable, and well know their different.

Relationship between fiber optic cable and fiber patch cord:

A fiber patch cord is really a fiber optic cable capped at either end with connectors that permit so that it is rapidly and conveniently linked to CATV, an optical switch or other telecommunication equipment. Its thick layer of protection can be used to connect the optical transmitter, receiver, and the terminal box. This is known as "interconnect-style cabling".

What types of connectors ought to be used?

There are a number of connector styles available on the market including LC, FC, MT-RJ, ST and SC. There are also MT/MTP style connectors which will accommodate up to 12 strands of fiber and occupy far less space than other connectors. This connector is intended for use with indoor loose tube no-gel cable constructions. However, typically the most popular connectors are SC, which push in then click when seated, and ST, also known as bayonet style, which are pushed in and twisted to lock. That needs to be considered when creating product selections.

What kind of jacket rating and kind do you require?

Fiber cable jackets are available in many styles. For example, fiber could be Indoor only, Outdoor only, Indoor/Outdoor, Tactical also it can also provide Plenum or Riser ratings.

Jacket color is relatively standardized.

a) Multimode = Orange

b) 50/125um 10G = Aqua

c) Single Mode = Yellow

d) Indoor/Outdoor or Outdoor = Black

e) Custom jacket colors are also available for indoor fiber cables

Whether you are your residential or commercial environment. FiberStore provides a wide selection of fiber cables, and other fiber optic cables related prodcuts, such as fiber patchcord, fiber optic connector, fiber transceiver. No matter how complex or simple your installation needs are, we've the expertise to offer you the right products and knowledge for both your fiber optic cable, custom fiber optic assembly and fiber optic connector needs.

Fiber optics has high bandwidth and can transmit data over longer distances. Turn to buy fiber optic cable, you may confused as there are so many types of cables and it's difficult to figure them out. An optical fiber cable consists of a center glass core surrounded by several layers of protective material. The outer insulating jacket is to prevent interference. The construction design and choices of materials are vital in determining characteristics of a cable. The design factors for some types of fiber optic cables are listed below.

Indoor cables- Fire safety is the number one factor in selecting indoor cables, particularly those that run through plenum spaces. Indoor cables must pass the flame-retardant and smoke-inhibitor ratings specified by NEC.

Outdoor cables- Moisture resistance and temperature tolerance are the major factors when choosing materials for outdoor environment cables, like waterproof cables and outdoor cables do. They also need to be ultraviolet (UV) resistant.

Aerial/Figure 8 Self-Supporting Cables- Aerial cables must endure extreme temperature ranges from sunlight heat to freezing snow. They also must survive high wind loading.

Cable Jacket Materials

Polyethylene (PE). PE (black color) is the standard jacket material for outdoor fiber optic cables. PE has excellent moisture C and weather-resistance properties. It has very stable dielectric properties over a wide temperature range. It is also abrasion-resistant.

Polyvinyl Chloride (PVC). PVC is the most common material for indoor cables, however it can also be used for outdoor cables. It is flexible and fire-retardant. PVC is more expensive than PE.

Polyvinyl difluoride (PVDF). PVDF is used for plenum cables because it has better fire-retardant properties than PE and produces little smoke.

Low Smoke Zero Halogen (LSZH) plastics. LSZH plastics are used for a special kind of cable called LSZH cables. They produce little smoke and no toxic halogen compounds. But they are the most expensive jacket material.

Typical fiber cables are made from silica glass, which causes refractions that delay the signal. The standard line is that fiber optic networks transfer data at the speed of light. But in reality, light travels about 31 percent slower through fiber optical cables than it does through a vacuum. But thats changing, researchers at University of Southampton in England have found a way to build cables that work at 99.7 percent of the speed of light in a vacuum. The researchers' solution is a hollow cable with special walls to prevent refraction. They call it an "ultra-thin photonic-bandgap rim".

Several recent breakthroughs in fiber optics research. For example, scientists at AT&T Labs-Research announced a new record in speed/distance through standard bulk fiber optic cable. And a DARPA-backed team at IBM has found a way to cut the energy use of short-distance fiber optics for supercomputing while doubling the speed.
