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.
