A passive junction of three or more ports in which the ports can be accessed in such an order that when power is fed into any port it is transferred to the next port, the first port being counted as following the last in order. 2. In radar, a device that switches the antenna alternately between the transmitter and receiver.
Industry:Telecommunications
A passive optical coupler having a number of input and output ports, used in network applications. Note: An optical signal introduced into any input port is distributed to all output ports. Because of the nature of the construction of a passive star coupler, the number of ports is usually a power of 2; i.e., two input ports and two output ports (a "two-port" coupler, customarily called a "directional coupler,"or "splitter"); four input ports and four output ports (a "four-port" coupler); eight input ports and eight output ports (an "eight-port" coupler); etc.

Industry:Telecommunications
A passive optical coupler having three ports (three fibers. ) Note 1: Two isolated inputs may be combined into one output; or one input, into two isolated outputs. Note 2: The amount of coupling loss, usually expressed in dB, between ports is determined by the design and construction of the coupler. Synonyms directional coupler, splitter, tee coupler.
Industry:Telecommunications
A patch bay designed for patching and monitoring of unbalanced data circuits at rates up to 1 Mb/s.
Industry:Telecommunications
A patch bay in which low-level digital data circuits can be patched, monitored, and tested. Note: A digital circuit patch bay can be either "D" type (unbalanced) or "K" type (balanced. )
Industry:Telecommunications
A patch bay that provides (a) the first access of most local user digital circuits in a technical control facility and (b) patching, monitoring, and testing capabilities for both high-level and low-level digital circuits.
Industry:Telecommunications
A patching facility designed for patching and monitoring digital data circuits at data signaling rates from 1 Mb/s (megabits per second) to 3 Mb/s.
Industry:Telecommunications
A patching facility designed for patching and monitoring of balanced digital data circuits that support data rates up to 1 Mb/s.
