Abstract: When a bi-directional TAP receives via a first multimode bi-directional fiber a signal transmitted by a storage array to a server, a collimator collimates the light of the signal towards a splitter. The splitter splits the signal into two portions. One portion is output to a second multimode bi-directional fiber connected to the server and the other portion is output to a monitoring system for analysis. When the bi-directional TAP receives via the second fiber a signal transmitted by the server to the storage array, the collimator collimates the light of the signal towards the splitter. The splitter splits the signal into two portions. One portion is output to the first fiber so that it can be received by the storage array. The other portion is output to the monitoring system. The bi-directional TAP can be a reflective or a transmitted type of TAP.

Abstract: A traffic access point (TAP) includes a first angle polished multimode multiple-fiber push-on (MPO) termination, a second angle polished multimode MPO termination, and multiple angle polished LC terminations. At the least, the first and second angle polished multimode MPO terminations are each coupled to a key aligned adapter.

Abstract: A network monitoring system for a multimode optical data network includes a filter based splitter and an avalanche photodiode detector-based detection subsystem. The system takes a very small amount of the energy from the main data stream to use as monitoring data signal. The filter based splitter operates in a manner that is fairly uniform among modes and permits very low energy levels to be diverted for monitoring without disrupting either the main or monitor data streams for any modes.
