  Définition

  A coupler for use with optical fibers, bundles, and cables, that operates on lightwaves propagating in one or both directions.

  Note :

  Uses of the coupler include tapping, directional control of propagation, drop-inserting, monitoring, branching, mixing, and wavelength multiplexing. The directional coupler is used in optical fiber communication systems, such as CATV and data-links for optical fiber measurements, to combine or split optical signals at desired ratios by insertion into a transmission line; e.g., a three- or four-port unit with precise connectors at each port to enable inputs to be coupled together and transmitted via multiple outputs.
