Connector Specifications Appendix B Connector and Cable Specifications XENPAK Module Ports (Catalyst 3750G-16TD Switch) The Catalyst 3750G-16TD switch uses XENPAK modules for 10-Gigabit fiber-optic connections to networks. See the Catalyst 3750 release notes for a list of supported XENPAK modules. Fiber-optic XENPAK modules use SC connectors, as shown in Figure B-6. Figure B-6 Fiber-Optic XENPAK Module SC Connector H8707 Tx Rx Table B-2 lists the XENPAK modules that the Catalyst 3750G-16TD switch supports. Table B-2 Catalyst 3750G-16TD Switch Supported XENPAK Modules XENPAK C3-XENPAK-10GB-LR XENPAK-10GB-ER C3-XENPAK-10GB-SR Wavelength 1310 nm 1550 nm 850 nm 1. FDDI = fiber distributed data interface Connector and Cable Type Maximum Distance SC, SMF 6.2 miles (10 km) SC, SMF SC; FDDI1 grade MMF SC; OM3 MMF 24.85 miles (40 km) 85.3 feet (26 m) 984.25 feet (300 m) For more information about XENPAK modules, see your XENPAK module documentation. Note The 10-Gigabit Ethernet XENPAK modules are referred to as 10-Gigabit Ethernet module ports in the software documentation. Console Port The console port uses an 8-pin RJ-45 connector, which is described in Table B-4 and Table B-5. The supplied RJ-45-to-DB-9 adapter cable is used to connect the console port of the switch to a console PC. You need to provide a RJ-45-to-DB-25 female DTE adapter if you want to connect the switch console port to a terminal. You can order a kit (part number ACS-DSBUASYN=) containing that adapter from Cisco. For console port and adapter pinout information, see Table B-4 and Table B-5.
