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, 1000BASE-CWDM, or 1000BASE-DWDM 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.
The Cisco 1000BASE-LX/LH GBIC (WS-G5486) fully complies with the IEEE 802.3z 1000BASE-LX10 standard. It allows for reaches up to 6.2 miles (10 km) over single-mode fiber (SMF) and up to 550 meters over multimode fiber (MMF).
