Structure: 

Fillers and loose tubes which contained optical fiber ribbons and was filled with jelly are SZ stranded concentrically around the non-metallic strength member form a cable core, on which is wrapped outside by water blocking tape, then applied a layer of aramid yarn and PE outer sheath. 

Features: 
1. High tensile strength, largest span reached to over 1000m. 
2. Non-metallic material, good performance of insulation. 
3. Special type of sheath material, good ability for tracking resistant, can be laid together with 500KV high voltage power transmission cables. 
4. Amorued with aramid, the anti-impact and anti-bullet properties keep a high standard. 
5. Light weight, no excessive requirement to the supporting tower. 
6. Easy to install and maintain. 
7. Low attenuation, low dispersion, stable control of excess length makes the optical cable perfect mechanical and environmental properties. 

Applications: 
High voltage, long span conditions in Power Transmission System or mazy terrain such as river spanning, mountains linking in Telecom System. 

Installation method: Self-support aerial 

Operating temperature range: -40 ~ +70° C 

Packing: Wooden drum or steel-wooden drum
