What is Optical Fiber?
Optical fiber, optical fiber or optical cable is a transmission channel made of glass or plastic that is used to transmit data through the media in the form of light from one place to another with very fast time and very large data (Saydam, 1997).
Definition, Types and Working Principles of Optical Fiber
Optical fiber was developed in the late 1960s made of dielectric material shaped like glass. It is inside this fiber that the light energy generated by the light source is channeled so that it can be received at the end of the receiver.

The difference between optical communication systems and ordinary communication systems lies in the process of sending the signal. In an ordinary communication system the information signal is converted into an electrical / electrical signal, then passed through a copper cable. After arriving at the destination the signal is then converted back into the same information as it was sent. Whereas in optical communication systems, information is converted into electrical signals and then converted again into optics / light. The signal is then passed through optical fiber, after arriving at the receiver, the light is converted back into an electrical signal and finally translated into information.
Advantages of Optical Fiber
The advantages of optical fiber compared to other transmission media are as follows (Widodo, 1995):
Has a very wide bandwidth. In a digital system it can reach the gigahertz order, so as to be able to carry enormous information.
Very small and inexpensive size, making it easy to handle and install.
Light signals are not affected by electrical noise or magnetic fields.
Gestures in the fiber cable are guaranteed safety.
Because there is no electric power in the fiber, there will be no explosion or spark. In addition, the fiber is resistant to toxic gases, chemicals, and water, making it suitable for planting underground.
The shrinkage is very low, thereby reducing the number of connections and the number of repeaters (repeaters). Which in turn will reduce costs
