52Filter (optics) — Coloured and Neutral Density filters Optical filters are devices which selectively transmit light of different wavelengths, usually implemented as plane glass or plastic devices in the optical path which are either dyed in the mass or have… …
53Add-drop multiplexer — An add drop multiplexer (ADM) is an important element of an optical fiber network. A multiplexer combines, or multiplexes, several lower bandwidth streams of data into a single beam of light. An add drop multiplexer also has the capability to add …
