GPIM-01 and GPIM-09 Network Connections
VHSIM-G6 User’s Guide 2-9
Since the GPIM-01 and GPIM-09 both have the same type of SC fiber
connector, the directions for connectivity are the same, except for when
the GPIM-09 is connected to multimode fiber. Refer to
Section 2.4.1
before connecting the GPIM-09 to multimode fiber.
Different size and wavelength fiber 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 cable. Check the fiber specifications in
Appendix B for each GPIM carefully before connecting a GPIM to the
network.
2.4.1 GPIM-09 Connection Using Multimode Cable
To connect the GPIM-09 to the network using multimode fiber, perform
the following steps:
1. Connect Launch Mode Conditioning cable to the multimode fiber on
both ends of the multimode cable, before connecting the VHSIM-G6
with a GPIM-09 to the multimode fiber cabling. See
Figure 2-6 .
NOTES
An odd number of crossovers (preferably one) must be
maintained between like devices so that the transmit port of
one device is connected to the receive port of the other device
and vice versa.
If the fiber optic cable being used has SC style connectors that
do not resemble MIC style connectors, or has SC connectors
on one end and a different type on the other, such as ST
connectors, ensure that the proper cable cross-over occurs.
NOTE
When using multimode fiber cable for the GPIM-09 (long wave
length transceiver), connect Launch Mode Conditioning cable
as detailed in the following procedure (
Section 2.4.1 ). The
following procedure is not needed when connecting single
mode fiber cable to the GPIM-09. Launch Mode Conditioning
cables are available from Cabletron Systems.
