In the actual production and application process, there are many failures due to the quality of the cable is not high caused by the Shenzhen LightS company recommends that users choose high-quality network cable. The high quality of the transmission of the network cable can lead to many failures. Such as:
1. Transmission speed drop:
The quality of twisted pair is one of the key factors in determining data transmission. Some cable manufacturers in the ultra-five UTP cable is wrapped in three or four types of UTP used in the pair, the counterfeiting method for the average user is difficult to identify. This so-called "five-class UTP" can not achieve the standard data transfer rate, up to 10Mbps or 16Mbps.
2. susceptible to signal interference
In order to reduce the interference of the signal, twisted pair cable in each pair of two insulated copper wire is twisted together from each other, and the same cable in the different pairs of different twist (that is, twisted coil how much). At the same time, the standard pair of twisted pair cable pairs are counterclockwise to twist around. But some non-regular manufacturers of cable production there are many problems:
① In order to simplify the manufacturing process, all pairs of cables in the cable twist the same density;
② The twist density of the two insulated wires in the wire pair is not
