Lasers for communications

conveying your message
Optical communication has been one of the driving forces in developing laser diode technology. Today, diode lasers are the key components of any broadband communication systems. They are employed as high speed transmitter in digital and analog fiber optic networks, to pump lasers in Erbium doped amplifiers (EDFAs), or as high-power pulsed lasers in test and measurement field.

Digital data transmission is an important part of modern society. Optical communication is any form of telecommunication that uses light as the transmission medium. An optical communication system consists of a transmitter, which encodes a message into an optical signal, a channel, which carries the signal to its destination, and a receiver, which reproduces the message from the received optical signal.

RF-over-fiber refers to transmission of analog multiplexed radio-frequency signals over an optical fiber medium. RF-over-fiber technology delivers unprecedented performance levels for a broad range of applications from wireless networks to high-frequency signal distribution in avionics and military.

Optical time domain reflectometry (OTDR) is a fast spreading test method for checking condition of fiber optic cablings. As the fiber optic networks are built closer and closer to end users the cablings are laid in increasingly demanding environment requiring easy and simple diagnostics. In OTDR high power laser pulses are shot out to fiber cabling and the condition of the fiber link can be determined form the back reflection of the pulses.
