Connecting the 2.5-Gbps Transponder Module
The 2.5-Gbps transponder module requires the following cables:
•
MTP to MTP connectors used for direct connections (blue)
•
MTP to 8 MU connectors used on OADM modules (gray)
•
MTP to 8 MU connectors used on line card motherboards (green)
•
MU to MU connectors (yellow)
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.
The line card motherboards and the mux/demux modules on the Cisco ONS 15540
ESPx connect to each other through the cross connect drawers using the MTP-to-8
MU breakout cables. The cable has one MTP connector at one end that 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 cable then runs down into the
cross connect drawer and connects to the cross connect panel with the 8 MU
cables. 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.
