Optic Fibre Industry

Optic fibre cables serve as the backbone of all telecom networks. In fact submarine cables, which comprise a major share of international data traffic are composed of optic fibre. India is a promising market volume-wise, given its vast geography. Next generation broadband technologies such as LTE and FTTx will drive the demand for even more optical fiber cables.

Optical fibre cables are made of a glass (or plastic) threads (fibers) to transmit data. An optic fiber cable is a collection of such threads, each of which is used to transmit messages modulated onto light waves. Optic fiber cables have several advantages: fiber optic cables have a much greater bandwidth than metal cables, allowing them to carry more data. This data can be transmitted digitally. Optic fiber cables are also less sensitive than metal cables to interference. Further, they are thinner and lighter than metal wires.

The structure of the cable is made up of two separate parts. The first part in the middle of the cable is called the core and that's the portion that the light travels through. The other part is wrapped around the outside of the core which is a layer of glass called the cladding. Basically, cladding works to keep the light signals inside the core. It can do this because it is made of a different type of glass/plastic to the core.

Two types of optic fibre cables are as follows:

1. Single-mode: This cable has a very thin core about 5-10 microns (millionths of a meter) in diameter. In a single-mode fiber, all signals travel straight down the middle without bouncing off the edges. Used in Cable TV, Internet, and telephones, Cables like these can send information over 100 km (60 miles).

2. Multi-mode: Multi-mode fibre cable is about 10 times bigger than the one in a single-mode cable. It can send information only for short distances and is used to link computer networks together.
