The fibers 250um are positioned in a loose tube made of a high modulus plastic. The tubes are filled with a water-resistant
filling compound.The tube is wrapped with a layer PSP .Between the PSP and the loose tube water-blocking material is applied to keep the cable compact and watertight. Two parallel steel wires are placed at the two sides of the steel tape.at last the cable is completed with a polyethylene (PE) sheath.
Characteristics:
1.Having good mechanical and temperature characteristics
2.The material loose tube having good hydrolysis resistance and high tensile strength
3.Inner of loose tube is filled with special ointment ,thus can give critical protection of optical fiber
4.Excellent crush resistance and flexibility
5.Two parallel steel wire ensure the tensile strength of optical cable
6.Small diameter 、light weight,make it install more easier
7.Standard:comply with YD/T 769-2010
