The Catalyst 6000 Family 8 and 16-port Gigabit Ethernet modules are IEEE 802.3z standards-compliant and support full duplex operation. The eight-port module (WS-6408-GBIC) can be configured with any combination of shortwave (SX) and longwave/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 16-port Gigabit Ethernet module (WS-X6416-GE-MT) supports MT-RJ connectors for multimode fiber.
