Generally made of metal or glass, it can be used to transmit
information within the network. There are three commonly used
network cables: twisted pair, coaxial cable and optical fiber cable
(optical fiber). Twisted pair is a data transmission line composed
of many pairs of wires. It is characterized by low price, so it is
widely used. Twisted pair is used to connect with RJ45 crystal
head, there are two kinds of STP and UTP, the most commonly used is
|Excavator type||Hydraulic pump number||Rotary motor||Travel motor|
Network cable standard :
When making network cables, according to actual needs, the
following two production standards are included:
EIA/TIA 568A standard
The order of the lines from the left: white green, green, white
orange, blue, white blue, orange, white brown, brown
EIA/TIA 568B standard
The order of the lines from the left: white orange, orange, white
green, blue, white blue, green, white brown, brown
Testing process :
You can use the network cable tester to test after the two ends of
the crystal head are completed.
If the eight indicator lights on the tester are all flashing green
in turn, it proves that the network cable is made successfully.
If any of the lights is red or yellow, it proves that there is an
open circuit or poor contact.
At this time, it is best to first press the crystal heads at both
ends and then use the network cable clamp to test again.
If the fault persists, check both ends. Whether the arrangement
order of the core wires is the same, if it is not the same, cut off
one end and re-make the crystal head according to the arrangement
order of the core wires at the other end.
The range of replacement parts are suitable for the following
