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.

Claims20

Dependent claims

A method comprising:

receiving, by a bi-directional traffic access point (TAP), a first signal via a first multimode bi-directional fiber, the first signal transmitted by a first system and destined for a second system;
receiving, by the bi-directional traffic access point (TAP), a second signal via a second multimode bi-directional fiber, the second signal transmitted by the second system and destined for the first system;
splitting, by a splitter of the bi-directional TAP, the first signal into at least a first portion and a second portion;
splitting, by the splitter of the bi-directional TAP, the second signal into at least a first portion and a second portion;
outputting, by the bi-directional TAP, the first portion of the first signal to the second fiber for receipt by the second system;
outputting, by the bi-directional TAP, the first portion of the second signal to the first fiber for receipt by the first system;
and
outputting, by the bi-directional TAP, the second portion of the first signal and the second portion of the second signal to a third system.

5 more elements

A bi-directional traffic access point (TAP) comprising:

a first termination configured to receive a first signal via a first multimode bi-directional fiber, the first signal transmitted by a first system and destined for a second system;
a second termination configured to receive a second signal via a second multimode bi-directional fiber, the second signal transmitted by the second system and destined for the first system;
and

split the first signal into at least a first portion and a second portion;
and
split the second signal into at least a first portion and a second portion;
wherein the first termination is further configured to output the first portion of the second signal to the first fiber for receipt by the first system;
wherein the second termination is further configured to output the first portion of the first signal to the second fiber for receipt by the second system;
and
wherein the second portion of the first signal and the second portion of the second signal are output to a third system.
