Description:
The ADSS structure of the optical cables adopts loose tube twisted structure. 250 um optical fibers are inserted into loose tube made of high modulus polyester and filled with non-metallic reinforcing members (FRP) around the center of the cable to form a round core. The gap in the core is filled with water-blocking ointment, Two layers of aramid yarn are twisted to reinforce the yarn. The gap in the core is filled with water-blocking ointment, and the inner sheath of polyethylene (PE) outside the core is then two-way. Two layers of aramid yarn are twisted to reinforce the yarn. Finally, polyethylene (PE) sheath or AT sheath are extruded.
All Dielectric Self-Supporting Cable-Single Sheath (4-144F) is a non-metallic cable which supports its own weight without the use of lashing wires or messenger cables, typically installed in overhead applications along power distribution or transmission
The span length of the cable ranges from 100m to 1500m.

Features and Advantages
The cable diameter is small, the weight is light, the span can reach 1500M, and the additional load to the tower is low.
High tensile strength, over 90KN
Non-metallic structure, good insulation, lightning protection
The aramid yarn has excellent production technology, uniform force, excellent stress-strain performance, excellent gunshot resistance and best anti-electric corrosion performance
No blackout construction, power line failure does not affect the normal transmission of optical cable
Smooth shape, so that the cable has superior aerodynamic performance
All-dielectric optical cable structure is conducive to installation and maintenance: wide temperature range, small linear expansion coefficient, meet the requirements of harsh environment

ITU recommendation G.657 specifies two classes of single-mode bend insensitive fiber patch cables: G.657 A and G.657 B. Each category (A and B) is then divided into two sub-categories: G.657.A1, G.657.A2 and G.657.B1, G.657.B2. The minimum bend radius of G.657.A1 fibers is 10 mm, of the G.657.A2 and G.657.B1 fibers is 7.5 mm and of the G.657.B2 fibers is 5 mm. Among, ITU-T G.657.A1 and ITU-T G.657.A2 fibers are fully compliant with ITU-T G.652.D fibers.
