Cable Structure:
The 250um bare fibers are positioned in a loose tube made of a high modulus plastic. The tubes are filled with a water-resistant filling compound. A Fiber Reinforced Plastic (FRP) locates in the center of the core as a non-metallic strength member. Tubes and fillers are stranded around the strength member into a compact and circular cable core. An Aluminum Polyethylene Laminate (APL) is applied around the cable core. Then the cable core is covered with a thin PE inner sheath, which is filled with jelly to protect it from water ingress. After a corrugated steel armor is applied, the cable is completed with a PE outer sheath.

Packing
The cable is supplied in lengths as specified in PI or as a requirement. Each length will be shipped on a separate non-returnable wooden drum. The minimum barrel diameter of the drum will not be less than 30 times the cable diameter.
The cable on each reel will be completely covered with a thermal wrap which is fastened to the cable by packaging straps. This wrap is reusable and provides excellent thermal and UV protection.
The cable ends will be sealed with plastic protection caps to prevent water penetration. The ends will be easily accessible for testing. A final inspection test report with attenuation performance data for each fiber is attached inside the drum.
