Note: When multimode fiber is used in long-distance applications, external, removable, mode-conditioning patch cords may be required to prevent differential mode delay (DMD). You can order mode conditioning patch cords through Nortel Networks:

SC-SC Mode-Conditioning Patch Cord 62.5/125 (part number AA0018035)

SC-SC Mode-Conditioning Patch Cord 50/125 (part number AA0018036)

1000BASE-XD

The Model 1000BASE-XD GBIC provides Gigabit Ethernet connectivity using SC duplex single-mode fiber connectors. High-performance optical transceivers enable Gigabit Ethernet link distances up to 50 kilometers (km) over single-mode fiber. The ports operate in full-duplex mode only.

Note: The Model 1000BASE-XD GBIC is based on proprietary signaling and is compatible with Accelar 1000 Series XD modules.

Table 5 describes standards, connectors, cabling, and distance for the Model 1000BASE-XD GBIC.
