CAUTION
When multimode fiber is used in long-distance applications,
external, removable, mode-conditioning patch cords may be
required to prevent differential mode delay (DMD). Excessive DMD
can cause an increase in the bit error rate (BER). You can order
mode conditioning patch cords through Nortel:
•
SC-SC Mode-Conditioning Patch Cord 62.5/125 (part
number AA0018035)
• SC-SC Mode-Conditioning Patch Cord 50/125 (part
number AA0018036)
