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.

1. INTRODUCTION
FAST ETHERNET (IOOBASE-X)
CABLE SPECIFICATIONS
This guide is intended for the system or network administrator
responsible for installing and monitoring a TRANSITION Networks
LAN Master™ TX-8 100BASE-TX 8-Port Hub. A working knowledge
of local area network (LAN) operations, including familiarity with
communications protocols used on interconnected LANs, is
assumed.
Due to the limited collision domain in 100BASE-X, use the shortest
cables possible to make a connection between any two devices.
Where collisions are not a consideration (full duplex), longer
cable may be possible.
The LAN Master™ TX8 Hub
The LAN Master™ TX8 100BASE-TX 8-Port Hub (HB-E-TX-8) is a
Fast Ethernet repeater designed to meet IEEE 802.3u 100BASE-TX
standards.
Effective cable distances are determined by ambient RF noise and
by signal loss in the cable. Since fiber has low signal loss/meter
and invulnerability to RF noise, fiber is the preferred medium for
extending distances.
100BASE-FX Cable and Connector Specifications
The physical characteristics of the 100BASE-FX cable must meet or
exceed IEEE 802.3 100BASE-FX specifications.
