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 these switches directly to a multi-protocol router.
3. As a general rule, 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 (3.1 miles) for single-mode fiber
• 1000BASE-ZX: 100 km (62 miles) for single-mode fiber
However, power budget constraints must also be considered when calculating
the maximum cable length for your specific environment.
