Fiber Optic Cabling For Beginners

Everybody understands that a structured cabling system is the foundation of every business network, offering connectivity in between servers, computer systems, and other network devices and permitting both voice and information to be sent worldwide. When it comes to information cabling, there are different mediums available to bring that data, transferring it from point A to point B. Generally, twisted pair copper cable has actually been and is still currently used as the most typical type of structured data cabling, transferring data through copper wires. As innovation continues to advance nevertheless, and the demand for much faster, advanced techniques of networking grows, fiber optic cabling is quickly on its way to becoming the next generation requirement in data cabling.

Advantages of fiber optic cabling include:

oLonger distances - Signals executed fiber optic cable can increase to 50 times longer than those using copper wires due to low attenuation (signal loss) rates, without requiring a signal repeater to preserve the integrity of the signal over fars away as copper wire cables do.

oIntrusion avoidance - With copper wire cable systems, it is possible to remotely identify a signal being broadcast over the cable television, which can provide unwanted security loopholes. This is not a problem with fiber optic cable as its dielectric nature makes remote detection impossible, and getting to the fiber itself would require a physical intervention that would be quickly thwarted by a well positioned surveillance system.

oInstallation enhancements - Longer lengths, smaller size, and lighter weight of fiber optic cable make installation and upgrades easy and less pricey than with copper cables.

oHigher bandwidth and information transfer rates - With wider bandwidth, more information has the ability to be transferred at a much faster speed. This permits shorter download times and increased network performance.

oEMI Immunity - Fiber optic cables can be set up in areas with high Electro-magnetic Interference (EMI), as the absence of metal electrical wiring makes the cable television completely unsusceptible to EMI.

Depending on your specific information cabling requirements, there are two various types of fiber optic cable readily available to meet your requirements:

oMulti-Mode fiber - Multi-mode fiber has a large core size, where light may be transmitted through numerous paths on its way to its location. This gives multi-mode fiber high bandwidth, but just retaining dependability over short ranges generally less than 8 miles, limited by modal dispersion.

oSingle-Mode fiber - Single-mode fiber has a much smaller sized core diameter than multi-mode, enabling only one path for light to be transmitted through. Single-mode is utilized for long distance transmission, well going beyond the limits of multi-mode, and is not limited by modal dispersion.

Various environments likewise require various types of cabling systems to guarantee the fiber remains in good condition. Depending on where you are setting up the cable television, there are two fundamental kinds of fiber cabling systems that can be used:

In a typical fiber inside plant cable television system, separately coated fibers are placed around a dielectric strength member core, and then surrounded by a subunit coat. Some inside plant fiber cabling systems have an outer strength member as well, implied to offer defense to the entire cable. For within plant installation, fiber ribbon-cable systems are also often utilized.

Outdoors plant fiber cabling systems are composed of private gel-filled subunit buffer tubes which are positioned around a main core strength member. Within each subunit buffer tube, buffer coated fibers are placed around a strength member.

So now that you have a basic understanding of the various types of fiber optic cable, you can decide which particular gadgets are appropriate for your particular installation. For instance, say you are having a fiber optic system installed to be run for more than 375 feet through a warehouse. This length is too long for a copper wire cable system to bring information, but multi-mode fiber can manage it quickly. An indoor plant installation would appropriate for this situation, since the cable is being run inside your home without any environmental variables to stress over. In order to user interface your brand-new fiber optic system with an existing Ethernet system, you will either need to use a dedicated switch or media converter, or a switch with GBIC (gigabit interface converter) modules. This will transform electrical signals to optical signals, and vice versa, permitting the seamless flow of data through both of the cable television mediums. Next, it is necessary to choose which method of protection you are going to use for the fiber optic cable. The two offered alternatives are: running the fiber through an innerduct to home and protect the fiber, or using armored fiber which has built in security. Both ready approaches of protection.

Pre-Installation Checklist: What you need to understand

- Setting up fiber through innerduct, or is armored fiber a much better method to go?
- How far is the fiber cable being run; multi-mode or single-mode?
- Which method of converting the two cable systems will be utilized so they may interact?
- Is this an indoor installation, outside fiber optic cable installation companies installation, or both?

Low system expense, integrated with a longer life span than copper cabling makes fiber optic cabling the finest worth hands down when it comes to structured cabling. Fiber optic cabling uses a structured cabling system that is designed to accommodate future applications and technological advancements, making fiber optic cabling the "cabling of the future". If you plan on installing a data cabling system that you want to last as long as possible and have unrivaled performance, fiber optic cabling is the way to go.


In a common fiber inside plant cable system, individually covered fibers are positioned around a dielectric strength member core, and then surrounded by a subunit jacket. The two available options are: running the fiber through an innerduct to house and protect the fiber, or using armored fiber which has built in protection. Low system cost, combined with a longer life expectancy than copper cabling makes fiber optic cabling the best value hands down when it comes to structured cabling. Fiber optic cabling offers a structured cabling system that is designed to accommodate future applications and technological developments, making fiber optic cabling the "cabling of the future". If you plan on installing a data cabling system that you want to last as long as possible and have unmatched performance, fiber optic cabling is the way to go.
