Cisco Prisma II Optical Switch Modules Data Sheet
Available Languages
Description
If you’re looking for optical path redundancy and using the Cisco® Prisma® II best-in-class architecture, the Prisma II Optical Switch (OPSW) is the right choice. The high-density OPSW (Figure 1) is a 1 x 2 switch designed to fit directly into a Prisma XD chassis or, with a host module adaptor, a standard Prisma II chassis.
The optical switch module in the Prisma II XD chassis module form factor features Subscriber Connector/Angle-Polished Physical Contact (SC/APC) connectors for input and output optical connections. For use in the full-height Prisma II chassis, a host module adaptor is available.
Features
● High-density design that allows up to 16 OPSWs in a Prisma II XD chassis or up to 24 in a standard Prisma II chassis with redundant power supplies
● Energy-efficient design with low power consumption per module
● Optical switches allow for network primary/secondary redundancy
● Multiple setup and control options include:
◦ Local control through a Local Craft Interface (LCI)
◦ Local monitoring through an Intelligent Communications Interface Module (ICIM)
◦ Remote monitoring through a ROSA status monitoring and control element manager
● OPSW modules have multiple modes of operation and user-settable trigger values
Table 1 gives specifications of the OPSW.

Notes:
1. Optical input power of -3.0 dBm or greater is required to maintain the full user-settable threshold range. When the optical input power is less than -3.0 dBm, there is a 1-for-1 reduction in threshold range.
2. Insertion loss of module with 0.25-dB loss per mated connector pair for a total connector loss of 0.5 dB. Actual connection loss may be less or more depending on mating connector compatibility.
3. With APC connectors.
4. Noncondensing external to the Prisma II or XD chassis.
