There’s a lot of emphasis within the government sector with the AV industry on using optical fiber because of its ability to prevent, or otherwise deter, security intrusions. Optical fiber also eliminates some other problems inherent in twisted-pair cable, including near-end crosstalk (NEXT) and electromagnetic interference (EMI).

While fiber optic cable itself is cheaper than an equivalent duration of copper cable, fiber optic cable connectors and the equipment needed to install them have typically been more expensive than their copper counterparts. By having an increased emphasis on protecting digital information, however, optical fiber is becoming more cost-competitive over the last few years. Armored Fibre Cable in Fiberstore is also popular.

The ability of fiber optic cable to meet the evolving needs of government AV/IT end users is a good reason behind integrators to know a little more about it. Outdoor Fiber Optic cable is common used in our daily life. Here is a look at the anatomy of a fiber optic cable.

Basic Construction of a Fiber Optic Cable

A fiber optic cable consists of five main components: core, cladding, coating, strengthening fibers, and cable jacket.

Basic Construction of a Fiber Optic Cable

Core: This is the physical medium that transports optical signals from an attached light source to a receiving device. The main is a single continuous strand of high-purity glass or plastic whose diameter is measured in microns (lower than the diameter of a human hair). The larger the core, the more light the cable can carry, which correlates to a higher data transfer rate.

Cladding: It is a thin layer that's extruded over the core and can serve as the boundary that contains the light waves (more about this later), enabling data to travel through the length of the fiber.

Coating: It is a plastic coating within the cladding to reinforce the fiber core, help absorb shocks, and provide extra protection against excessive cable bends. This doesn't have any effect on the optical waveguide properties, though.

Strengthening fibers: These elements help protect the core against crushing forces and excessive tension during installation. The types of materials can range from Kevlar, to wire strands, to gel-filled sleeves. Sometimes light-absorbing glass is added between your fibers, to prevent light that leaks out of one fiber from entering another. This reduces cross-talk between your fibers.

Cable jacket: This is the outer layer, or sheathing, from the cable. Its purpose is to protect the cable from environmental hazards, including construction work, fishing gear, as well as sharks, which are often attracted to the electrical fields created by signal conductors to repeaters.

Now there is a good news that I think you need to know, Fiberstore is doing with 30% discount of the price on fiber optic cables and if you want to buy Fibre Optic Cable, Fiberstore is your best choice.
