Design & Construction


ZTT fiber optic cable has a construction of optic fiber, loose tube or tight buffer or semi-tight buffer, strength members (FRP, Steel wire, Aramid yarns, Glass yarns, etc.), water blocking material (tube jelly, cable jelly, water blocking yarns, water blocking tape, etc.), armor (steel tape, aluminum tape, steel wire armor, FRP armor, etc.), cable sheath (PE, AT, LSZH, FRPE, PVC, Nylon, etc.). Meet with all kinds of operating environment.

Reference Standards

ZTT optical cable meet the international standards of IEC series (such as IEC 60794-1, IEC 60794-2, IEC 60794-3, IEC 60794-4, etc.), and can be supplied according to customers’ requirements of standards such as IEEE, EIA/TIA, BS EN, ANSI series, etc. ZTT also can produce optical cable with special requirements including rodent/termite protection, flame retardant, fire resistance, all-dry type, micro-bundle, invisible, low friction type, etc.

ZTT Cable was established in 1992 and issued stock in 2002. As the backbone of thispublic company, optical cable factory manufactures ZTT’s all kinds of optical cables.

ZTT ADSS (All Dielectric Self-Supporting) and ribbon optical cable in communication has been listed in the National Torch Plan and been regarded as national new product.


ZTT 1000m and shorter span ADSS is the first one to pass national-level appraisal and set 3 records (one hundred million aeolian vibration, one hundred thousand wave, 1,000-hour salt spray test of jacket). These records make ZTT's ADSS passed most tests in peer competitors.

ZTT pays close attention to researching and developing product quality. We cooperate with Shanghai Communications University, Nanjing University of Post and Telecommunications, and have spent 30 millions on the optical fiber technology research centre and have its own intellectual property.
