The fibers are positioned in a loose tube made of a high modulus plastic. The tubes are filled with a water-resistant filling gel. A layer of aramid yarn is applied around the cable core as additional strength member. Then, the cable is completed with a black PE outer sheath. The optical fiber is made of high pure silica and germanium doped silica. UV curable acrylate material is applied over fiber cladding as optical fiber primary protective coating. The detailed data of optical fiber performance are shown in the following table.

l Non-mental design can prevent the cable from radio interference and magnetic wave interference。
l Specially designed compact structure is good at preventing loose tubes from shrinking.
l Aramid yarn ensures good performance of tensile strength.
l Loose tube filling compound ensure good moisture resistance performance.
l Good flexibility
l High dense fiber packed, small diameter and light weight; it's the better option for lowing installation process.
