Fiber-optic Communication Versus Electrical Communication

Home / Electronics / Fiber-optic Communication Versus Electrical Communication

Cables.Greetings people and today the topic of discussion is the comparison of Fiber optic communication and Electrical Communication.

What is Fiber Optic Communication:
Fiber-optic communication is a method of transmitting information from one place to another by sending pulses of light through an optical fiber. Creating the optical signal involving the use of a transmitter, relaying the signal along the fiber, ensuring that the signal does not become too distorted or weak, receiving the optical signal, and converting it into an electrical signal.

What is Electrical Communication:
Electrical Transmission is the transmission of Information by converting it to Electrical Voltage signal and transmitting it. In a communication system, a transmitter encodes a message into a signal, which is carried to a receiver by the communications channel. For example, the words “Mary had a little lamb” might be the message spoken into a telephone. The telephone transmitter converts the sounds into an electrical voltage signal. The signal is transmitted to the receiving telephone by wires; and at the receiver it is reconverted into sounds.

Advantages of FOC over EC:
1. Optical fiber is generally chosen for systems requiring higher bandwidth or spanning longer distances than electrical cabling can accommodate.
2. The main benefits of fiber are its exceptionally low loss (allowing long distances between amplifiers/repeaters), its absence of ground currents and other parasite signal and power issues common to long parallel electric conductor runs (due to its reliance on light rather than electricity for transmission, and the dielectric nature of fiber optic), and its inherently high data-carrying capacity.
3. There is no Cross talk problem in fiber optics unlike EC.
4. Electrical Transmission are preferred medium of communication for short distance communication
