That part of the chromatic dispersion (spreading) that occurs in a single-mode fiber as some of the light passes through the cladding and travels at a higher velocity than the signal in the core, due to the cladding

(1) The distance between two corresponding points in a series of waves. (2) With respect to optical fiber communications, the distance an electromagnetic wave travels in the time it takes to oscillate through a complete cycle. Wavelengths of light are measured in nanometers or micrometers. Wavelength is preferred over the term frequency when describing light.

|WDM Wavelength division multiplexing||
A method of carrying multiple channels through a fiber at the same time (multiplexing) whereby signals within a small spectral range are transmitted at different wavelengths through the same optical-fiber cable. See also frequency division multiplexing.

A piece of equipment or location at which twisted-pair cabling is terminated to permit reconnection, testing, and rearrangement. Cross-connects are usually located in equipment rooms and telecommunications closets and are used to connect horizontal cable to backbone cable. Wire cross-connects typically use a 66- or 110-block. These blocks use jumpers to connect the horizontal portion of the block to the backbone portion of the block.

A wireless bridge is a hardware component used to connect two or more network segments (LANs or parts of a LAN) that are physically and logically (by protocol) separated. It does not necessarily always need to be a hardware device, as some operating systems (such as Windows, Linux, Mac OS X, and FreeBSD) provide software to bridge different protocols.
