Central Loose Tube Mining Optical Fiber Cable
Central Loose Tube Mining Optical Fiber Cable
The central loose tube cable, 200μm or 250μm, are positioned in a loose tube which is made of a high modulus plastic. The tubes are filled with a water-resistant filling compound. The tube is wrapped with a layer of PSP longitudinally. 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, over a thin inner PE sheath. The optic fiber cable is completed with a polyethylene (PE) outer sheath.
Features:
Good mechanical and temperature performance
High strength loose tube has good performance of water proof and high strength
Special tube filling compound ensure a critical protection of fiber
Crush resistance.
Two parallel steel wires ensure tensile strength
PSP enhancing moisture-proof and anti rodent
Good water resistance material prevent longitudinal seepage
Blue flame retardant PVC as second sheath to make the cable has good flame retardant performance.
