Live traffic continues through the system link, while monitored traffic is sent to the monitoring port electronics. The Pretium EDGE Tap Module uses an advanced optical coupler to reduce insertion loss and increase the distance over Ethernet and Fibre Channel connections.

Other passive optical tap devices are separate components that take up rack space, introduce additional losses, and limit network design options. The Pretium EDGE Tap Module is the first to combine the functionality of an optical interconnect, cross-connect, and tap into a single, easy-to-use structured cabling module.

Unlike a separate passive component, Corning's integrated approach allows monitored ports to be added or removed without interrupting the live network connection, providing flexibility for interconnect or cross-connect designs. Furthermore, by locating the tap port links on the back of the module, the Pretium EDGE Tap Module creates a zero-U configuration, improving rack utilization.

As part of the Pretium EDGE family of solutions, the Tap module is fully compatible with Pretium EDGE hardware as a standard module, enabling the "pay as you grow" capability on the "tapping" port.
