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.
Table 5 describes standards, connectors, cabling, and distance for
the Model 1000BASE-XD GBIC.
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)
Note: The Model 1000BASE-XD GBIC is based on
proprietary signaling and is compatible with Accelar
1000 Series XD modules.
