You have now completed the installation of a GBIC in to a Catalyst 4003 or Catalyst 4006 module.
Mode-Conditioning Patch Cord
When using the LX/LH GBIC with 62.5-micron diameter MMF, you must install a mode-conditioning
patch cord (Cisco product number CAB-GELX-625 or equivalent) between the GBIC and the MMF
cable on both the transmit and receive ends of the link. The patch cord is required for link distances
greater than 984 feet (300 meters). For more information on the patch cord, see the Catalyst 4003 and
4006 Switch Installation Guide.
