HOW TO
CRIMP A LAN CABLE TO RJ 45 CONNECTORS .
A:- HOW TO MAKE AN
ETHERNET CABLE
Purchasing Ethernet cables can be quite expensive and
pre-made lengths are not always the length you need. Making Ethernet cables is easy with a box of
bulk Category 5e Ethernet cable and RJ-45 connectors that are attached to the
cut ends of your preferred cable length.
B:- Bulk
Ethernet Cable - Category 5e or CAT 5e.
(You may also use Category 6 or CAT6 cabling which has
higher performance specifications and is about 20% more expensive than CAT5e.)
C:- Bulk RJ45 Crimpable Connectors for CAT-5e
or
Bulk RJ45 Crimpable Connectors for CAT-6
D:- RJ-45 Crimping tool
E:- There are two kinds of Ethernet cables you can make,
Straight Through and Crossover.
STRAIGHT THROUGH
Ethernet cables are the standard cable used
for almost all purposes. It is highly recommend you duplicate the color order
as shown on the left. Note how the green pair is not side-by-side as are all
the other pairs. This configuration allows for longer wire runs.
F:- CROSSOVER CABLES -
The purpose of a Crossover Ethernet cable
is to directly connect one computer to another computer (or device) without
going through a router, switch or hub.
G:- Here's
how to make a standard cable:
cut into the plastic sheath about 1 inch (2.5 cm) from the
end of the cut cable. The crimping tool has a razor blade that will do the
trick with practice.
H:- Unwind
and pair the similar colors.
Pinch
the wires between your fingers and straighten them out as shown. The color
order is important to get correct.
Use
scissors to make a straight cut across the wires 1/2 Inch (1.3 cm) from the cut
sleeve to the end of the wires.
Push
the wires into the connector. Note the position of the blue plastic sleeve.
Also note how the wires go all the way to the end.
A view
from the top. All the wires are all the way in. There are no short wires.
WRONG
WAY - Note how the blue plastic sleeve is not inside the connector where it can
be locked into place. The wires are too long. The wires should extend only 1/2
inch from the blue cut sleeve.
WRONG
WAY - Note how the cables do not go all the way to the end of the connector.
CRIMPING
THE CABLE ... carefully place the connector into the Ethernet Crimper and cinch
down on the handles tightly. The copper splicing tabs on the connector will
pierce into each of the eight wires. There is also a locking tab that holds the
blue plastic sleeve in place for a tight compression fit. When you remove the
cable from the crimper, that end is ready to use.
For a
standard "Straight Through" cable, repeat all steps and wire color
order on the other end of cable. For a cross-over cable, the other end will
have a different color order as shown by the crossover picture above.
Make
sure to test the cables before installing them. An inexpensive Ethernet cable
tester does this quite well.
NOTE - The maximum cable length of CAT-5, CAT-5e or CAT-6
Ethernet cable is 328 feet or 100 meters.
