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. Avoid using flow control on a port connected to a hub unless it is actually

required to solve a problem. Otherwise back pressure jamming signals may

degrade overall performance for the segment attached to the hub.

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 (6.2 miles) for single-mode fiber

• 1000BASE-LH: 80 km (49.7 miles) for single-mode fiber

However, power budget constraints must also be considered when calculating

the maximum cable length for your specific environment.
