| Minimum standard of LED display screen system for network cable | ||||
In the practical cases of the company, it is concluded that the network cable also has an impact on the use of LED full-color screen
Many failures are caused by the poor quality of network cable, so chuangkaiguang advocates that users choose high-quality network cable. The poor transmission quality of network cable will lead to many failures. For example:
1. The transmission speed decreases
The quality of twisted pair is one of the key factors to determine the data transmission of LED full color screen. Some cable manufacturers in the super five UTP cable wrapped in the 3 or 4 types of UTP used in the wire pair, this method of counterfeiting is difficult for ordinary users to distinguish. This so-called "five types of UTP" can not reach the standard data transmission rate, the maximum is 10Mbps or 16mbps.
2. Easily disturbed by signals
In order to reduce the disturbance of LED full-color screen signal, each pair of twisted pair cable is made of two insulated copper wires twisted with each other, and different pairs in the same cable have different degree of twist (that is, the number of twisted coils). Together, the twisted pair in the standard twisted pair cable is twisted anticlockwise. However, there are many problems in the cables produced by some informal manufacturers
① In order to simplify the manufacturing technology, the twist density of all pairs in the cable is the same;
② Twisting density of two insulated conductors in a pair
