    Get a complete view of the traffic on your fiber optic network without any disruption or downtime. With the Single-Channel Optical Tap, you can keep data flowing and users working while you get on with your work. Set it up and monitor network traffic, troubleshoot problems, and run test equipment with no interruption in data flow. Because you can leave the tap inserted permanently without interfering with network operation and minimizing points of failure, you can easily connect and disconnect different devices. Use the tapswith network and protocol analyzers, security monitoring devices, remote monitoring applications, RMON probes, and more.

    Use the tap on either side of the full-duplex link under test and a standard full-duplex analyzer connection. It copies traffic from one optical linek for one optical monitoring device.

    The Tap has LC connectors and split the full-duplex signal in 50/50 ratios from the network into two signals. One is sent back to your network and the other is sent to your monitoring device (a dual-receive capture card is required).

    You can use the tap anywhere, or mount up to three in a standard 19“ rack. Just order the Rackmount Bracket.
