Connecting Twisted-Pair Copper Cable to UTP/STP
Connector (10BASE-T/100BASE-TX)
Ensure that the correct cable type is installed to support the highest speed
and mode of operation to be selected. Though Category 3 cable is
adequate for the 10BASE-T installation, Category 5 cable is strongly
recommended, since Category 3 cable can NOT be used for 100BASE-TX.
10BASE-T AND THE ETHERNET COLLISION DOMAIN
•
Refer to the 5-Segment Rule (page 6) before installing half-duplex
10BASE-T cable.
•
Installing full-duplex twisted-pair cable avoids collision domain
considerations; distances remain
≤
100 meters.
100BASE-TX AND THE FAST ETHERNET COLLISION DOMAIN
•
Refer to the 512-Bit Rule (page 7) before installing half-duplex
100BASE-TX cable.
•
Installing full-duplex twisted-pair cable avoids collision domain
considerations; distances remain
≤
100 meters.
•
NOTE: A Fast Ethernet collision domain can have ONLY ONE
CLASS I repeater OR TWO CLASS II repeaters.
INSTALLING CABLE
To install 10BASE-T or 100BASE-TX cable:
1. Locate or build 10BASE-T or 100BASE-TX cables:
•
803.2 (10BASE-T) or 803.2u (100BASE-TX) compliant (page
11)
•
with Straight-through or Crossover RJ-45 cable/connectors as
required for site installation (page 7)
•
with RJ-45 plug connectors installed at both cable ends.
2. Connect RJ-45 plug connector at one end of 10BASE-T or
100BASE-TX cable to bridging media converter RJ-45 jack
connector.
3. Connect RJ-45 plug connector at other end of 10BASE-T or
100BASE-TX cable to RJ-45 jack connector on network device.
