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.
