1+1 Redundancy Module
Overview
The 1+1 Redundancy module is an interface for two fiberoptic cables for carrying identical data.
The cables backup each other. The same information is transmitted on both fibers. Normally, the
data on the primary link (cable connected to the Primary ports) is received by the nodes. When
the primary link fails, i.e., no reception is detected, the secondary link becomes the active link.
Two models are available:
1)
EM800-RED
: 1+1 Redundancy module
with
full Service module functionality.
2)
EM800-RED/NS
: 1+1 Redundancy module
without
Service module functionality.
shows how 1+1 Redundancy modules can be applied.
