1-Port OC-192c/STM-64 POS RPR XFP SPA Overview
Mate Interface Cables
The 1-Port OC-192c/STM-64 POS/RPR XFP SPA supports two mate interface configurations:
•
Mate between two OC-192c SPAs in the same SIP
•
Mate between two OC-192c SPAs in adjacent SIPs
Two 1-Port OC-192c/STM-64 POS/RPR XFP SPAs are connected using a 40–pin connector copper mate
cable. The length of the cables allow only two possible connection scenarios, next slot horizontal and
same slot vertical. This assumes that the chassis is mounted vertically.
Figure 2-23
shows the mate cables
used to connect the SPAs.
Figure 2-26 SPA Mate Cables
Note
The RPR mate cable is only necessary when the SPA is to be used in RPR mode. It is not needed in POS
mode. Support for the RPR feature is dependent on the platform software release feature content. Verify
support for the RPR feature support via SPA datasheets or by contacting your Cisco representative.
