Information
Installing the Patch Cord
As shown in the illustration below, connect the patch cord to the ProCurve 
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 B-1. 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).
