10-Port Gigabit Ethernet SPA Overview
SFP-GE-T Modules
The 1000BASE-T SFP module (SFP-GE-T) is compliant with IEEE 802.3:2000 and plugs into a
standard Gigabit Ethernet SFP module port. It operates on standard Category 5 wiring and has an RJ-45
connector.
The SFP-GE-T is hot swappable. The SFP-GE-T module supports 10/100/1000 speeds. The half- and
full-duplex modes are supported in the 10/100 speed configuration. Also, auto-negotiation is supported. The
SFP-GE-T maximum cabling distance is 328 feet (100 m).
SFP Module Cabling and Connection Equipment
Table 3-23 provides cabling specifications for the SFP modules that can be installed on the Gigabit
Ethernet SPAs. 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).

2. A mode-conditioning patch cord is required. When using the SFP-GE-L with 62.5-micron diameter MMF, you must install a
mode-conditioning patch cord between the SFP module and the MMF cable on both the transmit end and the receive end of the
link when link distances are greater than 984 ft (300 m).
