70-km Gigabit Ethernet GBIC Transceiver Installation Guide For 3Com Gigabit Interface Converter (GBIC) Transceivers Description The Gigabit Interface Converter (GBIC) ports on your system connect to Gigabit Ethernet networks through a GBIC transceiver (Figure 1), providing a high-speed connection over fiber-optic cable. The transceiver connects to the network using a fiber-optic duplex Subscriber Connector (SC). You can remove and replace the transceiver with the system on (which is called hot-swapping). Figure 1 70-km Gigabit Ethernet GBIC Fiber-Optic Transceiver To ensure optimal performance, compatibility, and regulatory compliance, use only GBIC transceivers that 3Com supports.
