Application Notes
1. Full-duplex operation only applies to point-to-point access (such as
when a switch is attached to a workstation, server or another switch).
When the switch is connected to a hub, both devices must operate in
half-duplex mode.
2. For network applications that require routing between dissimilar
network types, you can attach the switch directly to a multi-protocol
router.
3. As a general ru le, the length of fiber optic cable for a single switched
link should not exceed:
• 1000BASE-SX: 550 m (1805 ft) for multimode fiber
• 1000BASE-LX: 10 km (6.2 miles) for single-mode fiber
• 1000BASE-ZX: 70 km (43.5 miles) for single-mode fiber
However, power budget constraints must also be considered when
calculating the maximum cable length for your specific environment.
