The Cisco 1000BASE-T Gigabit Interface Converter (GBIC) is an ideal solution for Catalyst ® 6500, 4000, 3550, 2950, 3500 XL and 2900 XL Series switch customers, providing full duplex Gigabit Ethernet connectivity to high-end workstations and between wiring closets over existing copper network infrastructures. This GBIC technology leverages the industry’s flexible, standards-based 1000BASE-X design, allowing for a simple and low-cost migration path to Gigabit Ethernet. There are two key product applications for the Cisco 1000BASE-T GBIC: connectivity to high-end workstations and distribution and wiring closet interconnectivity.

The Cisco 1000BASE-ZX GBIC (WS-G5487) operates on ordinary single-mode fiber optic link spans up to 43.4 miles (70 km) long. Link spans of up to 62 miles (100 km) are possible using premium single-mode fiber or dispersion shifted single-mode fiber. The GBIC provides an optical link budget of 21 dB - the precise link span length will depend on multiple factors such as fiber quality, number of splices, and connectors.
