WITCH

 3300 SM

Gigabit Ethernet is designed to run over four media:

■

Single-mode fiber optic cable, with connections up to 5km.

■

Multimode fiber optic cable, with connections up to 550m.

■

Balanced, shielded copper cabling, with connections up to 25m.

■

Category 5 cabling, with connections up to 100m.

Table 4   Gigabit Ethernet cabling

The Switch has a Gigabit Ethernet fiber optic 1000BASE-SX port that 
provides a 1000Mbps full duplex connection to another Gigabit Ethernet 
device. Full duplex allows packets to be transmitted and received 
simultaneously and, in effect, doubles the potential throughput of a link.

For the SuperStack 3 Switch 3300 SM:

■

Use Multimode fiber optic cable (see 

 for details).

■

The 1000BASE-SX port is permanently fixed at 1000Mbps with full 
duplex.
