Mode Conditioning Patch Cord
N o t e
Most of the time, if you are using good quality graded-index multimode fiber
cable that adheres to the standards listed in this appendix, there should not
be a need to use mode conditioning patch cords in your network. This is
especially true if the fiber runs in your network are relatively short.
Installing the Patch Cord
As shown in the illustration below, connect the patch cord to the transceiver
with the section of single mode fiber plugged in to the Tx (transmit) port. Then,
connect the other end of the patch cord to your network cabling patch panel,
or directly to the network multimode fiber.
If you connect the patch cord directly to the network cabling, you may need
to install a female-to-female adapter to allow the cables to be connected
together.
Example: Connecting a Mode Conditioning Patch Cord for Gigabit-LX
Make sure you purchase a patch cord that has appropriate connectors on each
end, and has multimode fibers that match the characteristics of the multimode
fiber in your network. Most important, the core diameter of the multimode
patch cord must match the core diameter of the multimode cable
infrastructure (either 50 or 62.5 microns).
