ABSTRACT:
A network TAP that provides access to data communicated in a network. The TAP includes a first port for connecting to a pluggable optoelectronic module such as an optical transceiver, a link port for connecting to an optical link configured to receive and send data to the optical transceiver, and a TAP port for relaying diverted optical data to a storage and/or analyzing device. Couplers are used to split the optical signals entering the TAP from the first port and/or the link port such that a useable portion of the optical signal(s) can be stored and/or analyzed. The TAP also includes optical devices for relaying optical signals between components in the TAP.
