100BASE-TX Cable and Connector Specifications

The physical characteristics of the 100BASE-TX cable must meet or exceed IEEE 802.3u 100BASE-TX specifications.

100BASE-TX CABLE SPECIFICATIONS

Category 5 wire or better is required. Either shielded twisted pair (STP) or unshielded twisted pair (UTP) can be used. DO NOT USE FLAT OR SILVER SATIN WIRE.

Category 5:

 

Gauge

24 to 22 AWG

Attenuation

20 dB/1000’ @ 10 MHz

Impedance

100 Ω ±10% @ 10 MHz

Maximum Cable Distance:

100 meters (330 feet)

100BASE-TX CONNECTOR CHARACTERISTICS:

The 100BASE-TX connectors are standard RJ-45 connectors with standard pinning.

The two active pairs in a 100BASE-TX network are pins 1 & 2 and pins 3 & 6. Use only dedicated wire pairs (such as blue/white & white/blue, orange/white & white/orange) for the active pins. 100BASE-TX cable for unlike devices (such as hub to terminal device) must be configured as straight through; 100BASE-TX cable for like devices (such as hub to hub or terminal device to terminal device) must be configured as crossover.
