Sfp-Ge-T Modules; Sfp Module Cabling And Connection Equipment - Cisco 7600 series Hardware Installation Manual

Chapter 3 Overview: Cisco 7600 Series Router Shared Port Adapters
When shorter lengths of single-mode fiber are used, it may be necessary to insert an in-line optical
attenuator in the link to avoid overloading the receiver.

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).
Only full-duplex mode is supported.

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).

Insert a 10-dB in-line optical attenuator between the fiber-optic cable plant and the receiving port
on the 1000BASE-ZX module at each end of the link whenever the fiber-optic cable span is less than
15.5 miles (25 km).
Insert a 5-dB in-line optical attenuator between the fiber-optic cable plant and the receiving port on
the 1000BASE-ZX module at each end of the link whenever the fiber-optic cable span is equal to or
greater than 15.5 miles (25 km) but less than 31 miles (50 km).
