Connecting the Cisco ONS 15540 ESPx
Connecting the 10-GE Transponder Module
Note
78-16436-01
The 10-GE transponder module requires the following cables:
•
MTP to 4 MU (aqua)
MTP to 4 MU (rose)
•
•
Y cable (blue)
MTP to MTP
•
When you make direct connections in the Cisco ONS 15540 ESPx, you connect
the line card motherboard MTP connections directly to the MTP connections on
the mux/demux modules or mux/demux motherboards. This connection requires
just one MTP cable storage drawer. There are two different cables you can use for
direct connections depending on your configuration:
MTP to MTP
•
•
MTP to 2x MTP (y cable)
The line card motherboards and the mux/demux motherboards on the Cisco ONS
15540 ESPx connect to each other through the cross connect drawers using the
MTP-to-MU breakout cables. The cable has one MTP connector at one end that
usually is plugged either onto the MTP connector at the base of the line card
motherboard or onto the MTP connectors on the mux/demux modules.
The motherboards can be installed in any of slots 2 to 5 and 8 to 11; however,, the
transponder modules in the line card motherboards, or the channels within the
band, must be in increasing order from top to bottom.
Allow two minutes for the 10-Gbps laser on the 10-GE transponder module to
warm up before it transmits traffic.
