Twisted Pair Cable Termination for Ethernet Communication
The twisted pair cable used for Ethernet communication depends on the network speed.
The LAN connectors support both 10BASE-T (10 Mbps Ethernet) and 100BASE-T
(100 Mbps Fast Ethernet), half-duplex and full-duplex Ethernet connections. Terminate
the RJ-45 connectors for Ethernet communication with straight-through or crossover
termination standards.
NOTES:
•
Do not use standard telephone cables. Telephone cables do not support Ethernet
or Fast Ethernet.
•
To avoid transmission errors, do not stretch or bend the cables.
•
Crossover cable
— Wire one end of the twisted pair cable with the T568A standard
and the other with the T568B standard. Use this to connect to a computer.
•
Straight-through (patch) cable
— Wire both ends of the twisted pair cable with the
T568B standard. Use this to connect to a switch, hub, or router.
