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.
