PM OPS

Single Optical Protection Switching module Ekinops PM PM OPS Overview

The PM OPS is an optical switch module for the Ekinops 360 family that provides for a 1+1 (50 ms) or "Optical UPSR/SNCP" protection capability either at the WDM line level or card level. The PM OPS cards are used in pairs, one at each end of the optical signal to be protected. At the head end of the signal to be protected, the PM OPS provides a "Bridge" capability. It accepts an input signal and replicates that signal across two fiber outputs, providing an exact copy. On the other end of the signal to be protected, the PM OPS provides a "Select" capability. It receives the two outputs generated by the "Bridge" end PM OPS and "Selects" the one that is not currently in a loss of signal state. If neither is in a loss of signal state, the signal selected is dependent on the mode the PM OPS is programmed for. This means of protection is what is commonly referred to as a "Head end bridge and tail end select."

The PM OPS can be placed between a source optical signal and the Ekinops 360 transponders in order to provide card level protection.

The PM OPS can also be used to replicate and protect the composite WDM signal being transported by the Ekinops 360 system. In order to do this, one can place the PM OPS on the line output of an Ekinops 360 system where it can receive the composite WDM signal for replication.

Applications

The PM OPS can be used for any application that requires line level or card level protection. The PM OPS is rate agnostic so, when used for card level protection, it can accept any optical signal as an input for protection meaning that it can be used to protect any service type. This type of redundancy is particularly important for applications like disaster recovery, datacenter interconnect, and for carrier services where a high level of availability has been committed.
