The Catalyst 6000 Family eight-port Gigabit Ethernet modules is IEEE 802.3z standards-compliant and supports full duplex operation. The eight-port module can be configured with any combination of short-wave (SX) and long wave/long haul (LX/LH) Gigabit Interface Converters (GBICs). All Gigabit Ethernet ports have SC-type connectors for multimode fiber (MMF) or single mode fiber (SMF).The eight-port Gigabit Ethernet module in the Catalyst 6000 Family supports GigaBit Interface Converter (GBIC) modular technology to ensure customers have the maximum flexibility in configuring physical network interfaces in their Gigabit Ethernet network. GBICs enable the customer to intermix any combination of 802.3z-compliant 1000BaseX interfaces on a port-by-port basis. GBICs are hot swappable and provide easy selection or change of interfaces. Cisco is offering a 1000BaseLX/LH interface that is fully compliant with the IEEE 802.3z 1000BaseLX standard, but has the ability to go up to 10 km over single mode fiber, 5 km further than garden-variety 1000BaseLX interfaces. The 1000BaseZX standard has the ability to transmit traffic up to 100 Km over dispersion shifted fiber.
