The meaning of 12-core optical cable. The 12-core optical cable is a communication cable with the same transmission speed as light. The 12-core optical cable has wide bandwidth, fast transmission speed, good confidentiality, anti-electromagnetic interference, good insulation, long life and good chemical stability.

12-core fiber optic cable commonly used models. The commonly used models of 12-core optical cables are mainly divided into two types: GYXTW central tube type (armored) and GYXTY central tube type (non-armoured).

1. The structure of GYXTW 12-core optical cable is to put 250μm optical fiber into a loose tube made of high modulus material, and the loose tube is filled with waterproof compound. The loose tube is longitudinally wrapped with a layer of double-sided plastic-coated steel tape (PSP), and a water-blocking material is added between the steel tape and the loose tube to ensure the compactness and longitudinal water-blocking of the optical cable. Vinyl sheathed cable.

2. The structure of GYXTY 12-core optical cable is to put 250μm optical fiber into a loose tube made of high-modulus material, and the loose tube is filled with waterproof compound. A layer of water blocking layer is attached to the outside of the loose tube, and two parallel steel wires are placed on both sides to extrude a polyethylene sheath into a cable.
