72-core optical cable is a communication cable with a transmission speed like light. The 72-core optical cable has wide bandwidth, fast transmission speed, good confidentiality, anti-electromagnetic field interference, good insulation, long life and good chemical stability.
The commonly used models of 72-core optical cables are mainly divided into two specifications: GYXTW center tube type (armored) and GYXTY center tube type (unarmored).
The structure of GYXTW 72-core optical cable is to insert 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 wrapped longitudinally with a layer of double-sided plastic-coated steel tape (PSP). 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. Place it on both sides. Two parallel steel wires are then extruded with polyethylene sheath to form a cable.
The structure of GYXTY 72-core optical cable is to insert 250μm optical fiber into a loose tube made of high modulus material, and the loose tube is filled with waterproof compound.
A water-blocking layer is attached to the outside of the loose tube, two parallel steel wires are placed on both sides, and a polyethylene sheath is extruded to form a cable.
The loose tube material itself has good hydrolysis resistance and high strength. The tube is filled with special grease to provide critical sealing protection for the optical fiber. The PE sheath has good anti-ultraviolet radiation properties. The central strengthening core of a single steel wire contributes to the parallel and tensile properties of the optical cable. It is resistant to stretching, abrasion, impact, and flattening, and can be repeatedly bent, twisted, bent, and twisted (the bending angle does not exceed 90°). etc., has good mechanical properties and temperature characteristics. Double-sided corrugated steel strip (PSP) improves the moisture resistance of the optical cable. The 72-core optical cable has fast transmission speed, long distance, good confidentiality, anti-electromagnetic field interference, good insulation, and chemical resistance. Good stability, long life and low loss have good characteristics and economic benefits.
Suitable for long-distance communication and inter-office communication. Laying method: overhead. Applicable temperature range: -40℃-+60℃. Obtained UL certification.
The more commonly used 72-core optical cable models are GYTA layer-stranded optical cable, GYXTW center tube armored optical cable, GYTA53 double-sheathed layer-stranded optical cable, and GYTS armored layer-stranded optical cable
