Optical Switch Card for Diverse Route Network Protection
Scientific-Atlanta’s Prisma IP
™
Optical Switch Card is one of many new building
blocks for the Prisma IP Platform. The Optical Switch Card is a protocol
independent, wideband optical switch that can enable a network to perform high
speed (12ms) protection switching in diverse route supplied optical network nodes.
The Optical Switch Card has two optical inputs and one common optical output.
Each of the optical inputs is monitored for presence and power level of optical
carriers on its inputs. Switchover from one optical input to the other is activated if the
user-provisionable optical level threshold is passed. Front panel LEDs indicate input
and switch status, as well as overall card status.
There are several switching algorithms that can be selected from that permit
customizing the switching mode for your network application. The provisionable
operating modes include Automatic switching with both revertive and non-revertive
restoration, Forced (manual) switching, and Toggle switching modes.
