how to fiber optic cable pol to pol layer in Urdu And Hindi

Fiber optics is a technology that uses thin, flexible glass or plastic fibers to transmit information, such as data or voice signals, over long distances. The fiber optic cables are made up of a core, cladding, and buffer coating, which protect the fiber from damage and allow it to be easily handled during installation.
The process of transmitting information through fiber optics involves converting electrical signals into light signals using a device called a modulator. The modulator changes the electrical signals into light pulses that travel through the fiber optic cable at the speed of light. At the receiving end, the light pulses are converted back into electrical signals using a demodulator.
Fiber optics has several advantages over traditional copper wire communication. Fiber optic cables can transmit data over much longer distances than copper wire without the need for signal boosters. They are also less susceptible to interference from electromagnetic signals, making them more reliable for communication in areas with high levels of electromagnetic activity.
Fiber optics is widely used in telecommunications, internet connectivity, and cable television. It is also used in medical equipment, military communications, and industrial applications such as sensing and monitoring. As technology continues to advance, fiber optics will likely become even more ubiquitous and play an increasingly important role in our lives.
