3COM 3C16874 SWITCH 7700 4-PORT GBIC 1000BASE-X FABRIC SUB-MODULE

This sub-module is inserted within the switch fabric of the 3Com Switch 7700 4-Slot chassis and delivers four ports of high-performance Gigabit Ethernet switching with optional Gigabit Interface Converter (GBIC) ports for both fiber and copper connections. This is particularly helpful when Gigabit Ethernet ports are required for an uplink when using Fast Ethernet modules in the chassis payload slots. This sub-module is also an economical choice for supporting a small quantity of fiber connections where all other connections will be copper.
