What's the difference between the network cable with RJ45 connectors and the ordinary network cable?

Product Network Cable manufacturers are produced by signal attenuation interference detection, environmental protection detection, transmission speed, and a variety of industrial standards to measure, in addition to not professional production of network cable manufacturers, are generally very good.In fact, the network cable within 10 meters, whether finished or handmade, will not affect the normal access to the Internet for home users, because the local network card is generally 100M, the network cable transmission rate is generally greater than 100M, but our actual application is less than 20M, so even some attenuation will not affect the data transmission.The difference is that the network cable produced by professional cable manufacturers is easy to lose packets.

The quality of the network cable on the market is uneven, mainly on the performance of online material: (the following material from good to bad)

1. This kind of pure copper wire is a good wire. Under the same circumstances, the resistance of copper is the second smallest, so it can be made of high-quality wire.And suitable for POE power supply, small resistance can avoid the loss of electricity in the transmission process.
2. The quality of the aluminum wire is inferior to the copper wire, but the short distance use is not a big problem, so the home or small office terminal ----- switch line can choose this kind of line.This type of wire is only suitable for short distance POE power supply because the resistance is higher than copper wire.
In addition, many small partners must have found that there are two common network cables on the market now, one with a crystal head itself, and one needs to connect the crystal head by hand

Today, the network cable manufacturer tells you the profession is a statement, take the crystal head
We call as the network jumper referred to as the jumper, the latter is the general network cable that we often say, so
A. Why don't ordinary network cable come with crystal head (RJ45)
B. What is the difference between the two environments?
The two different process wire, there is a big difference:
Appearance: The jumper connection is T-568B, this logo is also shown on the jumper appearance
Wire core: the wire core of the network jumper is generally 7 cores and 8 strands, that is, the jumper has 8 cores, and each core wire is composed of 7 strands of fine core wire, while each core wire of the general network cable is single strand (single core conductor).
Network transmission signals are electrical signals, which are generally transmitted through the surface of conductors. According to this principle, the transmission capacity of jumpers is stronger than that of ordinary network cables. Meanwhile, the anti-interference ability of jumpers will also be improved.
