Mode Conditioning Patch Cord

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.
Figure A-1. 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).
NOTE:
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.
