Communication Telephone Cable (Outdoor)

Applications of large logarithmic communication cables: Mainly used for transmitting audio and analog signals at 150kHz and below, as well as digital signals at 2048kbit/s and below. Under certain conditions, they can also be used to transmit digital signals above 2048kbit/s. Introduction to HYV and HSYV indoor large logarithmic communication cables: Used for audio connections between program-controlled switch main distribution frames and exchange users, and can also be used for audio connections between other communication devices. They support low-rate data transmission, voice applications, digital telephony, fax, program-controlled switches, digital device connections, branches and trunks of integrated telecommunications systems, etc. Conductor diameters (mm): 0.40, 0.50, 0.60, 0.70, 0.80, 0.90.
