  • Publication number: 20160105237
    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.

  • Publication number: 20160091674
    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.

  • Patent number: 9294194
    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.

  • Publication number: 20060104392
    Abstract: Certain embodiments of the invention provide a method and system for TERC4 decoding using minimum distance rule. A plurality of bits may be received that may indicate addresses of samples of data. A lookup table may be generated based on the received plurality of bits to determine corresponding output samples of data. The received plurality of bits may be exclusive ORed with the generated corresponding output samples of data. A distance value for each sample of data may be calculated based on an output generated by the exclusive ORing of the received plurality of bits with the generated corresponding output samples of data. An error in each of the received samples of data may be corrected based on the calculated distance value.
