Optical Network Design and Implementation

H - I

hot swapping.

The process of replacing a module without bringing down the equipment. This process occurs by sliding an active module into a fully powered-up unit.

in-fiber Bragg grating.

An optical fiber grating is an optical fiber component consisting of a length of optical fiber wherein the refractive index of the core has been permanently modified in a periodic fashion, generally by exposure to an optical interference pattern as generated by an ultraviolet laser.

insertion loss.

The loss introduced into an optical system by the insertion of optical devices and/or splices measured in decibels (dB).

integrated optical circuits.

Similar in principle to electrical integrated circuits, but with the combining of many tiny versions of current optical ...
