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.When a switch is connected to a hub or any kind of shared media, you may want to turn off back pressure flow control to prevent jamming packets from being propagated throughout the hub.

3.As a general rule the length of fiber optic cable for a single switched link should not exceed:

•1000BASE-SX/LX: 550 m (1805 ft) for multimode fiber or 5 km (16404 ft) for single-mode fiber.

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