Limiting Connection Distances
Limiting Connection Distances
The length of your networks and the distances between connections depend on the type of signal, the
signal speed, and the transmission media (the type of cabling used to transmit the signals). For example,
fiber-optic cable has a greater channel capacity than twisted-pair cabling. The distance and rate limits in
this appendix are the IEEE-recommended maximum speeds and distances for signaling. You can get
good results with rates and distances greater than those described here, although you do so at your own
risk. You need to be aware of the electrical problems that may arise and compensate for them.
Uplink Port Transceiver Modules
Transceiver modules that plug into the front panel of the supervisor engine or route switch processor
provide the uplink ports for the router. Several types of transceiver modules are available:
small form-factor pluggable (SFP) modules, X2 modules, XENPAK modules, and Gigabit Interface
Converter (GBIC) modules.
Table B-3 lists the orderable part numbers for supported transceiver modules. In addition, the following
tables provide information about the modules and their cabling specifications:
• Table B-4 and Table B-5 provide information about 1GE uplink ports.
• Table B-6 and Table B-7 provide information about 10GE uplink ports.
• Table B-8 provides information about 1GE GBIC modules.
