Joining Broken CAT 5/5e Network
Last updated: 5/20/01
Q. Can I just join a broken CAT5 cable by soldering
the parts back together?
A. Soldering may cause problems. CAT
5 cable insulation melts extremely fast even with low wattage irons. The
wires cannot be untwisted more than ½ inch total. Use shrink wrap if
you try soldering. Radio Shack carries it. I would crimp
an RJ-45 plug on each end of the broken cable and “glue” them back together
with a CAT 5 coupler. Black Box and many others sell the couplers. Be
sure the coupler and plugs are rated for CAT 5 or 5e and that the plugs match
the type of cable. There are plugs for stranded core and solid core
cables. Horizontal runs are supposed to be solid core and can
be up to 90 meters long (100 meters if connected directly from a hub or switch
to a PC). The coupler may effectively reduce this length somewhat,
but I do not think so.
