Technical specifications
Central Loose Tube Cable GYXTW, 2~12 fibers, jelly filled and fiber contained central loose tube, copolymer coated steel tape, two parallel steel wires 1.2mm, PE outer sheath, G652D SM fiber, detailed specification on your request.
Features
- Low dispersion and attenuation
- Proper design, precise control for fiber excess length and distinct stranding process render the cable excellent mechanical and environmental properties
- The armoring of corrugate steel tape make cable have nice properties of moisture resistance and crush resistance
- With small cable diameter, light cable weight, easily to lay
- Operating Temperature : -40~+60 ℃
Description
Single jelly compound filled loose tube containing up to 24fibers color code as per color coding scheme. surrounded by moisture barrier bonded to polyethylene incorporating two steel wire strength elements. This cable is suitable for outdoor duct, direct burial or aerial applications.
