Uses: The horizontal twisted pair cable for digital communication is mainly used for the wiring between telecom lead-outs and floor distributor comprehensive system, as well as the wiring between the user telecom lead-outs and floor distributor comprehensive system. In order to meet the different reuqirements of users, this cable define into STP and UTP. STP cable will be free from outside interference and reduce error, STP cable general used in hospitals, Telecommunications, airport and ect.The standard wiring length is 90m and using the T568A or T568B installed method.
