Caution
If you plan to use a GBIC-LX/LH or WS-G5486 at distances greater than 984.25 feet (300 meters) over
50/125-micron or 62.5/125-micron multimode fiber, you must use the mode-conditioning patch cord to
prevent data transmission problems. (See the
“Attaching the Mode-Conditioning Patch Cord” section on
