Communication is the most important part of our lives these days. Whether it’s mobile phones, emails, etc.,the basic idea is to transfer messages from one point to another at high speed. This transmission of the signal is via multimedia transfer. The medium can be of 2 types:
– Cable transmission media
– Wireless transmission media
Among the means of transmission of cables you can choose between twisted cables, copper cables, fiber optic cables and many more. Fiber optic cables are mainly used to carry light. The cable is not a single cable, but it is a collection of individual cables in which each cable is given a plastic coating. The entire cable is also provided with a protective coating depending on the environment in which it will be used. The application environment will determine the robustness, durability and durability of the cable. The material used is mainly plastic or glass depending on the range of transmission. For the short range, plastic is used while for the medium and long range, glass is used.
The optical system has three components:
– Optical transmitter
– Optical receiver
– Real optical supports that connect the transmitter and receiver
The optical transmitter can be a LASER, a coherent light source, or a light-emitting diode. The actual propagation of light through the optical fiber is based on Maxwell’s equation.
Fiber optic cables are used for a variety of purposes ranging from long-distance telemetry to transmitting fast information from one node to another within a building. There are many advantages to using fiber optic cables. Some of them are as follows:-
– Unaffected by electromagnetic interference
There is no fiber interference or very little. Therefore, data security is maintained
Multiplexing of a large number of signals is possible, as you can also use high-frequency bandwidths
Ensuring safety in hazardous areas
– Much cheaper than other wired media
There are fewer problems with ground loops in such transmissions.
For some specific purposes, the color-coded cable is available. In total, 12 colors are used in cable markings. Each color has its own specific notes to the technicians who manage them. This method facilitates the use of these cables and prevents misadventures.
Today, hybrid cables are also used, which are a mixture of fiber optic cables and electrical cables. In these hybrid cables, information and power are transmitted together.
Fiber optic cables are the perfect choice if performance and safety are needed. It’s one of the important things to remember.
