Indigo
What Does Indigo Mean? Indigo is a spectral color between blue and violet at about 420 to 450 nanometers (nm) in wavelength. Today’s color scientists do not often recognize indigo as a separate color division and place it between blue and violet. Techopedia Explains Indigo Any wavelength of less than...

Dark Fiber
What Does Dark Fiber Mean?Dark fiber is unused optical fiber that has been laid but is not currently being used in fiber-optic communications. Because fiber-optic cable transmits information in the form of light pulses, a "dark" cable refers to one through which light pulses are not being transmitted. There are...

Add/Drop Multiplexer
What Does Add/Drop Multiplexer Mean?An add/drop multiplexer (ADM) is a critical element of an optical fiber network. It can combine (i.e. multiplex) several low-bandwidth streams of data into a single light beam; and simultaneously, it can drop or remove other low-bandwidth signals from the stream of data and direct them...

Multiplexer
What Does Multiplexer Mean? A multiplexer (MUX) is a network device that allows one or more analog or digital input signals to travel together over the same communications transmission link. The purpose of multiplexing is to combine and transmit signals over a single shared medium in order to optimize efficiency...
