What is fiber optic cable


An fiber optical cable is a cable form that consists of several optical fibers that are usually coated in their individual plastic protective coverings. Optical wires are used to transmit digital light information signals over hundreds of miles at a greater rate than those obtained via electric communication wires.

An fiber optic cable is a technology which transmits information by using glass (or plastic) threads (fibres). A optical fiber cable is made from a package of glass threads that can each transmit modulated messages to light waves.

In order to prevent light leakage to your environment, all optical fibers use the hair-like core of clear silicon coated with less refractive indexed cladding. It is usually coated with a high-fast, lightweight protective material like due to its extremely high sensitivity to optical fiber.


How fiber optic cable works


A fiber optical cable has a bandwidth more higher than metal cables that means more data can be transmitted and Fiber-optical cables are significantly lighter than metal wires and are much thinner.

A fiber optical cables are the main source of long-term, high-bandwidth communications between telephone businesses, multi-site organisations and other long-range uses, which were first commercially implemented in 1977.

If light signals transmitted through the optical fiber cable, the core and the coating are reflected in a range of twist bounces, which are followed by a process known as total internal reflection.

Due to the denser glass layers, light signals are not traveling at the velocity of light, instead they travel about 30% slower. In the interest of renewing and/or enhancing the signal throughout the trip, fiber optics transmission sometimes needs repeaters to regenerate the optical signal at remote intervals through conversion to the electrical signal, electrical processing, and optical transmission.

The optical cable structure begins with the external jacket, which consists of a powerful and often versatile material. The plastic cover used for bundling individual fiber optic cables is followed by. The transparent core, surrounded by a clear cover with a reduced refractive index, usually comprises of a optical fiber. Total inner reflection keeps light in the center.Due to the low refractive index cladding around, which rebounding light back when it attempts to flee, a single-wavelength or multi-wavelength light passes through the heart.

Type of fibre optic cable


1.Single-mode fiber.
2.Multi-mode fiber.


1.Single-mode fiber

The lower diameters of the glass fiber core reduce the likelihood of attenuation, namely the decrease in signal strength, using single-mode fibers over longer distances. The narrower opening isolates the light into a single light beam, allowing the signal to be extended over a more immediate range. Single mode fiber is also much larger than multimode fiber in bandwidth. The light source usually is a laser for single-mode fibres. In most cases a single-mode fibre is more costly because accurate calculations are required to generate a narrower opening for laser lighting.

2.Multi-mode fiber

For shorter distances multimode fiber is used because the bigger center opening enables light signals to rebound and to reflect more. The bigger diameter allows numerous light pulses to be sent simultaneously through the cable, leading to a greater transfer of information. However, this also implies that signal loss, decrease or interference is more possible. Multimode fiber optics typically use LEDs for light pulse creation.
