OPS Overview

 

The Optical Protection Switch provides 1+1 optical protection switching in a 1RU form factor. When used with diversely routed fiber pairs, the Optical Protection Switch can protect against fiber plant failure by switching to the good fiber pair. An optical splitter at the head end broadcasts the DWDM wavelengths on both fibers and a 1x2 optical switch at the tail end selects the surviving signal. Optical photo detectors at the switch end monitor power levels that are used for switching decisions.

Each chassis contains two OPS power cards for redundant power, an OPS system control card, a passive cooling unit, and slots for up to four OPS 1+1 module pluggables. Each OPS 1+1 module pluggable contains two independent switches. A fully populated chassis can support eight 1+1 protected links.

Management of the OPS is performed using a Web GUI, reachable through the local Ethernet ports on the OPS system control card. The OPS can also be discovered and monitored by the proNX Service Manager.
