Cables
Installing the Patch Cord
As shown in the illustration below, connect the patch cord to the Gigabit-LX
mini-GBIC 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. Connecting a patch cord
Make sure you purchase a patch cord that has LC connectors on the end that
connects to the Gigabit-LX mini-GBIC, and has multimode fibers that match
the characteristics of the multimode fiber in your network.
