The SFP modules used with the MRC cards are SONET/SDH-compliant (Telcordia Technologies
GR-253-CORE and ITU G.957) optical interfaces. The transmitter and receiver reside on the same
module and are interconnected to the fiber using small form-factor LC connectors. The SFP
modules in the MRC cards support provisionable automatic laser shutdown feature (ITU G.664) to
turn off the transmitting laser in the event of a fiber failure on the span. The SFP optical
parameters, including laser bias current, optical transmit power, and optical receive power, are
available through Cisco Transport Controller to enable simplified troubleshooting and advanced
warning of potential impending issues using user-configurable high and low threshold crossing
alerts. The SFP cages are angled down relative to the faceplate to reduce bend-induced stresses
on the optical fibers exiting the faceplate.
The Cisco ONS 15454 12-Port Multirate Optics Card adds significant value to users’ networks by
enhancing system flexibility, improving card-slot usage of the shelf assembly, reducing intershelf
complexity, and lowering system cost.
Applications
A Cisco ONS 15454 MSPP equipped with an MRC card provides application solutions for both
service providers and enterprise managers, including the two following examples.
Multiservice Aggregation and Transport System
The high-port-density and multiple-reach support of the MRC-12 card requires fewer cards to
perform the same function as multiple fixed-rate/reach cards (Figure 2).
Figure 3. MRC-12 Card Frees Up Cisco ONS 15454 Shelf Slots
The Cisco ONS 15454 shelf slots that are freed up by the MRC-12 card can be used for additional
revenue-generating services, such as Fibre Channel, 10/100/1000 Mbps Ethernet, and so on
(Figure 4).
