Appendix B Cable and Connector Specifications
Uplink Port Transceiver Modules
Table B-7 lists the cabling specifications for 10GE uplink ports, which are located on X2 or XENPAK
transceiver modules that plug into the RSP720-10GE and WS-SUP32-10GE-3B front panel.
Note The 10GE uplink ports on the RSP720-10GE support X2 transceiver modules only.
GBIC Module Cabling Specifications
Table B-8 provides cabling specifications for the 1000BASE-X interfaces on the Gigabit Interface
Converter (GBIC) modules installed in the Supervisor Engine 2. All GBIC interfaces have SC
connectors, and the minimum cable distance for all GBICs listed (MMF and SMF) is 6.5 feet (2 meters).
