Instruction Manual
2700 Series Repeater for use on a
Dual Redundant single fibre ring
The AMG2780R-DR-SF is a rackmount repeater designed to operate in a single fibre dual redundant
loop. It is designed to plug into a standard AMG2000 or AMG2005 rackmount system.
Functional Description
The AMG2780R-DR-SF receives an optical signal
from both a primary and secondary optical input.
In normal operation where connection of both the
previous unit and the subsequent unit are OK, the
optical signal on both the primary and secondary
routes is regenerated on the respective optical
outputs.
If the primary optical input signal is not present,
the unit shut down the primary output. If the
secondary optical input is not present the unit will
shut down the secondary optical output.
