C band (infrared)

Index C band (infrared)

In infrared optical communications, C-band refers to the wavelength range 1530–1565 nm, which corresponds to the amplification range of erbium doped fiber amplifiers (EDFAs). [1]

4 relations: Infrared, Optical amplifier, Optical communication, Wavelength.


Infrared radiation (IR) is electromagnetic radiation (EMR) with longer wavelengths than those of visible light, and is therefore generally invisible to the human eye (although IR at wavelengths up to 1050 nm from specially pulsed lasers can be seen by humans under certain conditions). It is sometimes called infrared light.

Optical amplifier

An optical amplifier is a device that amplifies an optical signal directly, without the need to first convert it to an electrical signal.

Optical communication

Optical communication, also known as optical telecommunication, is communication at a distance using light to carry information.

In physics, the wavelength is the spatial period of a periodic wave—the distance over which the wave's shape repeats.
