Wavelength division multiplexing (wdm), английский
The combining of two or more optical signals for transmission over a common optical path, usually a single fiber. wdm devices have a channel wavelength spacing greater than or equal to 50 nm. they typically separate a channel in one conventional transmission window (e.g., 1310 nm) from another (e.g., 1550 nm). types include wide wdm, coarse wdm, and dense wdm
Optical power, английский
