[Q] Can I join lengths of Cat5 using an RJ45 coupler?
[A] Yes. Joining two or more lengths of Cat5 cable using
an RJ45 coupler will work just fine, but it should be
considered a temporary solution to whatever connectivity issue
required the use of it in the first place. The more "connection
points" that you have in a cable, or in a network for that
matter, provide additional points where signal loss can occur.
If you must join Cat5 cable using a coupler, make sure
to rectify the problem with a proper length cable as soon as
possible to restore maximum performance to the device using
it.
Also,
it should be noted that if you are operating a (speed) certified
network, you are not going to be allowed to have any coupled
repair points in the network to begin with. If you absolutely
must have a temporary run of cable using a coupler, be sure
to mark it in an obvious manner so that it does not get overlooked
for replacement.
The
use of couplers should always be considered an emergency measure,
such as when a cable is accidentally severed and the cable cannot
be immidiately replaced. In such an instance, a new run of cable
should be made as soon as possible to avoid loss of signal and
poor performance.
Avoid
joining cable with couplers when possible.
