FREMONT, CA: Fiber-optic communication is the best alternative for gigabit and beyond gigabit data transport. Voice, video, telemetry, and data are all sent across great distances over local area networks or computer networks using this method of communication. Lightwave technology is used to transport data via fiber by converting electronic information into light in a fiber optic communication system. Large bandwidth, lightweight, transmission security, smaller diameter, long-distance signal transmission, low attenuation, and other unique characteristics of this type of communication technology make it a critical component of any communications infrastructure.

Unlike copper wire-based transmission, which relies exclusively on electrical impulses traveling through the cable, fiber optics transmission involves the transmission of light signals from one place to another. A fiber optic communication network also includes electronics for transmitting and receiving data and a light source and detecting devices.

The transmitter circuitry turns the input data, which is in the form of electrical signals, into a light signal with the aid of a light source. For efficient transmission, the amplitude, frequency, and phases of this LED source must remain constant and free of fluctuation. A fiber optic cable carries the light beam from the source to the destination circuitry, where the information is converted back to an electrical signal by a receiver circuit.

A photodetector and a suitable electronic circuit make up the receiver circuit, which can measure the optic field's magnitude, frequency, and phase. This method of communication use wavelengths just above the visual range, approaching the infrared region. Depending on the application, both LED, and Laser can be employed as light sources.

Fiber optical communications have therefore revolutionized the telecommunications sector by becoming the preferred technology for various services such as high-speed internet, Ethernet backbone infrastructure, and general data networking. Because IP-based equipment such as IP cameras, video conferencing units, and VoIP phones require increased bandwidth to transmit IP communications, fiber optic communication is becoming increasingly widespread in business networks. Because of these features, this communication can easily accommodate bandwidth-intensive devices.
