Connecting Fiber Optic Cables to GPIMs

3-23

Different size and wavelength fiber optic cables are used for different applications. The GPIM-08

and the GPIM-09 typically have a blue connector to indicate the long wavelength transceiver. The

GPIM-01 connector is typically black or beige, to indicate short wave length applications. Check

the fiber specifications in Appendix C for each GPIM carefully before connecting a GPIM to the

network.

Since the GPIM-01, GPIM-08, and GPIM-09 interfaces have the SC fiber connector, the directions

for connectivity are the same, except when the GPIM-09 is connected to multimode fiber. Refer to

Section 3.6.2 before connecting the GPIM-09 to multimode fiber.

3.6.2 GPIM-09 Connection Using Multimode Cable

To connect the GPIM-09 to the network using multimode fiber, refer to Figure 3-14 and proceed as

follows:

1. Connect the Launch Mode Conditioning cable

➀ to each end of the multimode fiber optic

cables

➁ before connecting the Long Wavelength Gigabit fiber optic device ➂ (e.g., 5PIM

module with a GPIM-09) to the multimode fiber optic cabling.

Figure 3-14 GPIM-09 Launch Mode Conditioning Cable Connection

NOTE: When using multimode fiber optic cable for the GPIM-09 (long wavelength

transceiver), connect the Launch Mode Conditioning cable as detailed in the following

procedure. The following procedure is not needed when connecting single-mode fiber

optic cable to the GPIM-09. Launch Mode Conditioning cables are available from

Enterasys Networks.
