Gigabit Ethernet
Table 2-6 provides the maximum transmission distance specifications for the
1000BASE-T and the 1000BASE-X interfaces, including the Gigabit Ethernet
switching modules and the supervisor engine Gigabit Ethernet uplink ports.
Table 2-7 lists the Gigabit Interface Converter (GBIC) channel insertion losses.
All optical GBIC interfaces have SC connectors, and the minimum cable distance
for the optical GBICs listed (MMF and SMF) is 6.5 feet (2 meters).
