Glossary

Mux is is a device that selects between several analogs or digital input signals and forwards the selected input to a single output line.

NCP is a network management module specially designed for DWDM equipment

OLP(Optical Line Protection) is a device used in pairs, one at each end of the optical signal to protect the network transmission line.

Optical Bypass Protection(OBP) is a kind of intelligent optical switch system which can bypass fault nodes in optical transmission networks to avoid breakdown of whole network communication. it can automatically switch by detecting the node's optical power or signal failure.

optical add-drop multiplexer (OADM) is a device used in wavelength-division multiplexing systems for multiplexing and routing different channels of light into or out of a single-mode fiber (SMF).

Optical-Electrical-Optical(OEO) is a type of repeater that corrects for distortion of the optical signal by converting it to an electrical signal, processing that electrical signal, and then re-transmitting an optical signal.

A Raman amplifier is an optical amplifier based on Raman gain, which results from the effect of stimulated Raman scattering. The Raman-active medium is often an optical fiber, although it can also be a bulk crystal, a waveguide in a photonic integrated circuit, or a cell with a gas or liquid medium

An SOA (Semiconductor Optical Amplifier) is a semiconductor element that amplifies light. Antireflective processing is applied on both facets of a semiconductor laser to eliminate the resonator structure. When light enters from outside the semiconductor, the light is amplified by stimulated emission.

a transceiver is a device that is able to both transmit and receive information through a transmission medium. It is a combination of a transmitter and a receiver, hence the name transceiver.
