The featured central office symmetrical cable is mainly used for audio connection between the main distributing frame of intra-office SPC exchange and PCB for SPC exchange subscribers. It can also be used for short-distance connection of internal communication equipment or short-distance connection between the communication equipment.
Several pairs of stranded wire are stranded unit by unit to become the cable with a certain pitch, it is finally cabled after different colored ribbons have been cabled unit by unit, and the non-hygroscopic polyester tape will be lapped out of the cable. For shielding effect, a single-side aluminum foil is lapped out of the cable core. The braided general screen made of multi stranded wires is installed out of the single-side aluminum foil. A rip cord is longitudinally put out of the polyester tape and it is finally covered with PVC external sheath.
