Title: Selecting the Correct RJ45 Connector Before Buying
1Selecting the Correct RJ45 Connector Before Buying
01
2Introduction
It is required to terminate every Ethernet cable
connector. Utilizing an RJ45 Connector is one
option. See Choosing the Right Termination -
Keystone Jack vs. RJ45 Connector vs. Field
Termination Plug for some excellent background
information on the best terminations to utilize
throughout your installation (and why). Although
there are some instances where using them is
unavoidable, RJ45 8P8C connectors are actually
not the ideal option for solid copper Ethernet
wire. Due to installation restrictions, you can
be forced to utilize this termination style, so
it's in your best interest to know how to choose
the proper one!

3Is a shielded connector necessary?
This one is simple. You should use shielded RJ45
connectors if the wire is shielded. Instead,
utilize unshielded RJ45 connections if the cable
is protected. If the fitting is correct from the
start (which it probably won't be), using a
shielded connector on an unshielded cable won't
help. Since unshielded Ethernet cable conductors
are frequently thinner than shielded conductors,
shielded connectors that are typically "upsize"
won't typically create proper electrical
connections.
Another thing to keep in mind is that its bad
form to use protected RJ45 connectors on
unshielded Ethernet wire since it can lead
someone to believe the cable is likewise
shielded. You shouldn't use unshielded connectors
on a shielded wire. For the cable shield to work
correctly, shielded cables must have shielded
connections (the outside of the metal connector
functions as an extension of the cable shield and
is used to bond to the ground).

4What you need to know about the Ethernet cable is
this
- The Ethernet cable's outer diameter is measured
in OD (the overall thickness). Typically, this is
stated in millimeters (mm). - Similar to conductor diameter, conductor
insulation diameter is frequently given in
millimeters and consists of the conductor wire
itself plus the thickness of the insulation. - whether the cable has stranded or solid
conductors - AWG copper gauge

5To choose the best RJ45 connector, you must
understand
- The maximum cable jacket OD the plug can take
- The range of conductor insulation diameters that
the plug can accommodate - whether the plug has two or three prongs. Both
stranded and solid copper conductors can be used
with three-prong plugs. Plugs with two prongs
only operate with stranded copper. - AWG copper gauge
Observe the potential tolerances (-/) for the
Ethernet cable's conductor insulation diameter.
Choose an RJ45 plug such that the nominal
diameter of the insulated conductors in the cable
you intend to use matches the middle of the
plug's fitting range. This will aid in taking
into consideration any variations in
manufacturing tolerance that can and do happen.
- The diameter of the conductor insulation is
0.96mm. - The overall cable thickness, or cable jacket, is
5.90mm. - 23AWG solid copper conductors are used in the
cable. - With those specifications in hand, we would then
need to select the true cable Cat6/6A
Pass-Through RJ45 connector (if you wish to use
pass through).

6Ideal Techniques
- When utilizing solid copper Ethernet, never try
to make an Ethernet patch cable with hand-crimped
RJ45 plugs on both ends. For this, get OEM
pre-terminated patch cords. If you're in a bind
and trying to make a patch cable out of solid
copper bulk Ethernet cable, utilise field
termination plugs at both ends. - Reduce the number of hand-terminated RJ45
connectors as much as possible. - When RJ45 connectors are required, staggered load
bar standard (solid-nosed) RJ45 plugs are
strongly advised for Cat6A terminations. When
operating at 10Gb/s, Cat6A must be pushed to
500MHz, which results in significant cross-talk
(NEXT) at the connector. I can obtain a 5.0 dB
better NEXT parameter when utilizing our Cat6/6A
RJ45 standard connector plugs than when using our
straight-across pass-through variety while
testing with our Fluke DSX-8000. By doing this,
you can choose to operate dependably at 10G or
remain at 1G. Our Cat6A Field Termination Plug is
a superior choice for high-speed connections that
require a male end. - Choose the medium price when purchasing cable and
connectors from various suppliers! For instance,
choose an RJ45 socket with an insulated conductor
range of 0.95 to 1.05mm if your Ethernet cable's
stated insulated conductor diameter is 1.00mm. It
also allows for tolerance fluctuations from lot
to lot, which on Ethernet cable can vary as much
as /-.05mm, giving you the optimum fit and
performance. - It is highly advised to use cable strain relief
boots to help prevent cable shift at the back of
the RJ45 connector, stabilizing the mechanical
connection and subsequently the electrical one.
The termination is always the system's weakest
link. Strain relief boots help you remember the
cable bend radius while relieving additional
strain on the termination connectors.
