GPIM NETWORK CONNECTIONS
The GPIM-01 and the GPIM-09 each have an SC style connector for the network port that is used
to connect to the Gigabit Ethernet network. Cabletron Systems offers fiber optic cables that use SC
style connectors which are keyed to ensure proper crossover of the transmit and receive fibers.

Fiber Optic Port Designations
Since the GPIM-01 and GPIM-09 both have the same type of SC fiber optic connector, the
directions for connectivity are the same, except for when the GPIM-09 is connected to multimode
fiber. Refer to
Section 3.7.1
before connecting the GPIM-09 to multimode fiber optic cable.
Different size and wavelength fiber optic cable is used for different applications. The GPIM-09
typically has a blue connector to indicate the long wave length transceiver. The GPIM-01
connector is typically black or beige, for multimode fiber optic cable. Check the fiber optic
