For digital communication, the horizontal cable should have the wiring between the communication terminal of the work area and the distribution frame between the transfer in the building's integrated wiring system, and the user's communication terminal to the distribution frame in the residential integrated wiring system Wiring, in order to meet the needs of different users, this cable is divided into shielded and unshielded. The shielded cable will not be affected by external interference and reduce bit errors. Shielded cables are generally used in hospitals, telecommunications, airports, etc place. The standard wiring length of this type of cable is 90m, and it is generally installed by T568A or T568B.
