Network data communications cable is mainly installed between constructions or integrated wiring system in constructions to transfer voice.data. vedio and other information. The transmission frequency of the fifth type is 100MHz, sixth type is 200-400MHz and the seventh type is 600 MHz. Fifth .sixth and seventh types can be divided into 2 pairs.4pairs.8pairs and 25pairs. The 4 pairs cable is widely used and the usage percentage is over 90%. According to screening structure, it can be divided into: Non-shielded UTP and shielded STP.FTP.SUTP.SSTP. Our company is developing fifth type.sixth type and seventh type cable in accordance with national standards and international advanced standards.
