Attaching the Mode-Conditioning Patch Cord

Step 1

Attach the patch cord to the LC-type connector on the SFP GBIC modules (2).

Step 2

Attach the network ends of your patch cord to the appropriate 1000BASEX equipment in your building cable plant (9).

Note

Ensure that you connect the TX and RX ports on one end of the patch cord to the RX and TX ports (respectively) on
the other end. Connect TX to RX and RX to TX.

A mode-conditioning patch cord can be used with the

GLC-SX-MM

or GLC-LH-SM to allow reliable laser transmission

between the single-mode laser source on the SFP GBIC module and a multimode optical fiber cable.
