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: 5 km (3.2 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.
