The Advantages Of Optical Fiber Communication

Many businesses are looking for a fiber-optic network provider for business because of the advantages it offers for their business. Optical Fiber technology has attracted many enterprises due to its performance, no interference, higher bandwidth, high data-carrying capacity, and low loss. Some of the benefits include:

1. Low Attenuation: The signal is attenuated at a low rate of only 0.2 dB/km because the fiber is made of glass.

2. Lightweight: In comparison with copper cable, optical fiber cable is very lightweight.

3. Long-Distance Signal Transmission: Laser light is used for transmitting data. So,  long-distances are not a problem.

4. Bandwidth: It has an extremely high bandwidth ratio.

5. Low Cost: The cost per transported bit is low because of the huge transmission rate.

6. Large Transmission Capacity: Hundreds of thousands of telephone channels can be easily transmitted over long distances.

How Does Optical Fiber work?

An Optical Fiber communication network consists of a transmitter and receiver, a light source, and detector devices such as a photocell.

Optical fibers are thin, prolonged wires made from plastic or glass that are many miles long. The strands look like human hair enclosed in bundles and are called optical cables. Through the use of light, the transmission of video, audio, or telemetry data signals over long distances is extremely fast and very easy. Unlike copper wires, where transmission solely depends upon the electric signals passing through the cables, optical fiber converts the electrical signals into light and signals the transmitter. Upon reaching the receiver, the light signals are converted back into electrical signals.

The entire process is called Optical Fiber Communication, and this is a step-by-step summary of how it works.

Transmitter Block: The analog data is first converted into digital data using the decoder circuit and is then passed through a light source transmitter which converts the signals into light waves.

Receiver Block: After reaching the receiver, the light detector, also known as a photocell, receives the light waves, amplifies it, and converts it into the proper digital signal, or analog signal, using the decoder circuit depending upon the output.

Optical Fiber Cable: Light travels through the optical fibers through total internal reflection in which the light particle photon repeatedly bounces off the cable walls.

Single-Mode Fibers: Single-mode fibers are used for the transmission of only one signal per fiber since they have small cores. Common uses include television and telephone sets.

Multi-Mode Fibers: Multi-mode fibers are used for the transmission of many signals per fiber since they have large cores. They are often used in LAN and computer networks.

Each fiber optical unit consists mainly of two parts--core and cladding. The core consists of the middle of the glass structure where light beam travels, and the cladding is another layer that protects the core and helps to keep the light signals safe.

Optical fiber cables are used in a variety of applications such as:

· Networking

· Broadcast/ CATV

· Defense/ Government

· Internet Communication

· Telecommunications

· Medical

· Industrial/ Commercial

Organizations consider all the advantages and disadvantages before making the move from copper cables to fiber optic. After weighing all the possibilities and calculating the additional cost involved for the installation of the new lines and equipment, it is not surprising that many have concluded that fiber optic is the only way to achieve the speed and durability they need for uninterrupted communications.
