Data Sheet

Cisco Gigabit Interface Converter

The industry-standard Cisco Gigabit Interface Converter (GBIC) is a hot-swappable

input/output device that plugs into a Gigabit Ethernet port or slot, linking the port

with the network. Cisco GBICs can be interchanged on a wide variety of Cisco

products and can be intermixed in combinations of 1000BASE-T, 1000BASE-SX,

1000BASE-LX/LH, 1000BASE-ZX, or 1000BASE-CWDM interfaces on a port-by-port

basis.

As additional capabilities are developed, these modules make it easy to upgrade to the latest

interface technology, maximizing investment protection. Figure 1 shows three Cisco GBIC

models.

Cisco 1000BASE-T GBIC

The Cisco 1000BASE-T GBIC (product number WS-G5483) connects a GBIC port to

Category 5 wiring via a standard RJ-45 interface. The maximum Category 5 wiring distance

is 328 feet (100 meters). For details, see the Cisco 1000BASE-T Gigabit Interface Converter

Data Sheet.

Cisco 1000BASE-SX GBIC

The Cisco 1000BASE-SX GBIC (WS-G5484) operates on ordinary multimode ﬁber (MMF)

optic link spans up to 1815 feet (550 m) long.

Cisco 1000BASE-LX/LH GBIC The Cisco 1000BASE-LX/LH GBIC (WS-G5486) fully complies with the IEEE 802.3z 1000BASE-LX standard. However, its higher optical quality allows it to reach 6.2 miles (10 kilometers) over single-mode fiber (SMF), compared with the 3.1 miles (5 km) specified in the standard. Cisco 1000BASE-ZX GBIC The Cisco 1000BASE-ZX GBIC (WS-G5487) operates on ordinary single-mode fiber optic link spans up to 43.4 miles (70 km) long.
