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 MMF

•1000BASE-LX: 5 km (3.1 miles) for SMF

•1000BASE-ZX: 100 km (62.1 miles) for SMF

However, power budget constraints must also be considered when calculating the maximum cable length for your specific environment.
