Cabling Requirements

Incorrect cabling is often the cause of network configuration problems. It’s important that you understand cabling requirements before connecting Fast Ethernet devices to the switch.

UTP requirements

The 100BASE-TX Fast Ethernet specification requires you use Category 5 (CAT5) unshielded twisted-pair (UTP) cabling to operate at 100 Mbps per second. If you use lower grade cabling (CAT3 or CAT4), you’ll get a connection, but will soon experience data loss or slow performance.

You’re limited to 100 meters between any two devices with UTP cable. However, you can extend the total diameter by installing a fiber optic media adapter and using fiber optic connections between switches, or between the switch and a router or bridge.

See pages 10–11 if you’re unsure whether your network topology meets these distance limitations.

Fiber optic requirements

The optional 100BASE-FX fiber optic media adapter (Intel product code ESMODFX) lets you use multimode fiber optic cable to connect two switches, or to connect the switch with a router or bridge. The media adapter uses an SC fiber optic connector.

With multimode fiber optic cable, signals can travel up to 412 meters with no repeater when the link is configured at half duplex. If configured at full duplex, the signal can travel up to 2 km.
