Terminating Twisted Pair Cables
Terminology
Twisted Pair Cable
is given this name because of how the pairs
of conductors from a single circuit are twisted
together for the purpose of cancelling out
electromagnetic interference.
Cable Types
Category 3 Cable (Cat 3) is the FCC
recommended cable for phone use, but can also be
used for data networks that are limited to 10 Mbs.
Category 5e and 6 Cable (Cat 5e and Cat 6)
both of these cables are used for computer data
networking. Both of these cables will support
10/100/1000 Mbs network speeds, the only
difference being that Cat 6 cables will have lower
transmission errors in a 1000 Mbs environment.
Data Jack
is used when more then one connection is going
to be used in a fixed location. Most commonly the
cables will be run through the wall to a data jack
in an office or at a work station.
Connectors
RJ-11 Modular Plug is a 2 pair or 4 wire
connector that is used when creating phone line
patch cords. Each connector can support up to
two phone lines.
RJ-45 Modular Plug is a 4 pair or 8 wire
connector that is used when creating patch
cables for computer data networks.
