2X155M Circuit Pack - Nortel Optical Multiservice Edge 6130 Planning Manual

2x155M circuit pack

The 2x155M circuit pack can be installed in the tributary slots of the
OME6130 chassis.
The 2x155M circuit pack supports pluggable optical and electrical transceivers
for the two STM-1 line interfaces. The STM-1 optical and electrical interfaces
use small form-factor pluggable (SFP) interfaces to deliver optical and
electrical rate and reach flexibility on a per port basis. The STM-1 optical
interfaces use SFP modules for short reach, intermediate reach and long reach,
and CWDM access applications. The STM-1 electrical interfaces use SFP
modules for intra office applications.
