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 this switch directly to a multi-protocol router. However, if you

have to interconnect distinct VLANs or IP subnets, you can take advantage of

the wire-speed Layer 3 routing provided by this switch.

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 (3.1 miles) for single-mode fiber

• 1000BASE-LH: 70 km (43.5 miles) for single-mode fiber

• 10GBASE-LR: 10 km (6.2 miles) for single-mode fiber

However, power budget constraints must also be considered when calculating

the maximum cable length for your specific environment.
