Poor network performance or no communications may occur as a

result of improper cable length or type.

If you have 100Base-TX (Fast Ethernet), some network problems may

be related to exceeding cabling distances. Refer to the standard IEEE

802.3u, Clause 29.3.1.2 on

Round Trip Collision Delay

. This

document specifies that the collision domain diameter must be

within the following limits:

❑

Under 328 ft (100 m) for UTP cabling

❑

Under 1,351 ft (412 m) for half-duplex fiber cabling (Fiber

standards under ANSI X3T12 specify 2 km for full-duplex fiber

cabling.)

Proper cable type must be used:

❑

100Base -TX requires Category 5 UTP.

❑

100Base-FX requires 62.5/125 1300 nm multimode fiber.
