Note The RPR mate cable is necessary only 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 by reviewing the relevant SPA datasheets or by contacting your
Cisco representative.
1-Port OC-192 STM-64 POS RPR XFP SPA Overview
The 1-Port OC-192/STM-64 POS/RPR XFP SPA is a single-height SPA that is installed in one SIP
subslot. The 1-Port OC-192/STM-64 POS/RPR XFP SPA provides SONET and SDH network
connectivity with a bandwidth of 9.95 Gbps.
For more information about SPA bandwidth, see the “Bandwidth Oversubscription” section in this
chapter. For more information about SPAs and their compatibility with SIPs and modular optics, see the
product overview chapter in this guide.
The 1-Port OC-192/STM-64 POS/RPR XFP SPA uses a 10-Gbps small form-factor pluggable optical
receptacle for each port allowing connection to single-mode optical fiber. For more information on the
optical fiber cables used with this SPA, see the “1-Port OC-192/STM-64 POS/RPR SPA Fixed Optical
Transceiver, 40-Pin Connector, and Cables” section on page 2-39.
