Chapter 3 Overview: Cisco 7600 Series Router Shared Port Adapters 5-Port Gigabit Ethernet SPA Overview SFP-GE-T Modules The SFP-GE-T (1000BASET copper SFP module) provides full-duplex Gigabit Ethernet connectivity to high-end workstations and between wiring closets over an existing copper network infrastructure. The SFP-GE-T maximum cabling distance is 328 feet (100 m). Note Only full-duplex mode is supported. SFP Module Cabling and Connection Equipment Table 3-38 provides cabling specifications for the SFP modules that can be installed on the 5-Port Gigabit Ethernet SPA. Note that all SFP ports have LC-type connectors. The minimum cable distance for the SFP-GE-S is 6.5 feet (2 m), and the minimum link distance for the SFP-GE-Z is 6.2 miles (10 km) with an 8-dB attenuator installed at each end of the link. Without attenuators, the minimum link distance for the SFP-GE-Z is 24.9 miles (40 km).

5-Port Gigabit Ethernet SPA Overview
SFP-GE-T Modules
The SFP-GE-T (1000BASET copper SFP module) provides full-duplex Gigabit Ethernet connectivity to
high-end workstations and between wiring closets over an existing copper network infrastructure. The
SFP-GE-T maximum cabling distance is 328 feet (100 m).
Note
Only full-duplex mode is supported.
SFP Module Cabling and Connection Equipment
Table 3-38
provides cabling specifications for the SFP modules that can be installed on the 5-Port
Gigabit Ethernet SPA. Note that all SFP ports have LC-type connectors.
The minimum cable distance for the SFP-GE-S is 6.5 feet (2 m), and the minimum link distance for the
SFP-GE-Z is 6.2 miles (10 km) with an 8-dB attenuator installed at each end of the link. Without
attenuators, the minimum link distance for the SFP-GE-Z is 24.9 miles (40 km).
