Cat5e Patch Cord With different kind RJ45 Connector for Option
Description:
In the whole network wiring, a kind of wiring method is used, but
both ends have RJ-45 plug network connection, whether it is the end
connection mode A, or the end connection mode B, in the network all
are common. The order of twisted pair is corresponding to the pin
number of the RJ45 head.
The Ethernet connection of 10M Ethernet uses 1, 2, 3, 6 number of
core wires to transmit data, and 100M Ethernet lines use 4, 5, 7, 8
numbers of core wires to transmit data. Why do we now use 4 pairs
of (8 core) twisted pair? This is mainly for the purpose of
adapting to more scope of use. Without changing the infrastructure,
it can meet the wiring requirements of various kinds of user
equipment. For example, we can use one pair of twisted pair to
achieve voice communication.
The provisions of 100BASE-T4 RJ-45 for twisted pair wire netting
are as follows:
1, 2 for sending, 3, 6 for reception, 4, 5, 7 and 8 are two-way
lines.
The 1 and 2 lines must be twisted pair, 3, 6 twisted pair, 4, 5
twisted pair, 7 and 8 twisted pairs.
Materials:
It adopts high purity oxygen free copper conductor, high quality
environmental protection PVC outer cover, 64K gold plated plug,
fashionable and durable. The ultra five standard four pairs of
twisted core line structures are used to combat external magnetic
wave interference, reduce misunderstanding bit rate, realize high
speed transmission of data, and be applicable to the
interconnection of personal computers with modem, jumper panel and
network distributor quality inspection.
Product and packaging conform to ROHS standard!

Gold-plateing crystal head, crystal head contact using 15U advanced
gold plating, anti-oxidation ability, is 3 times the life of the
ordinary crystal head, transmission is not exhaustion, and the
lifespan is long
Advantage of Gold-plating cystal connector,More durable, longer service life, stronger interference, less
household electrical appliances, smaller network transmission loss
and faster network speed.
