Product Description

Description
F-SST(Optical fiber composite stainless steel loose tube) is one kind of seamless tube, which is made of stainless steel, after laser longitudinal welding and jelly filling in the middle. With marvelous performance of longitudinal water resistance, the tube is perfect to maintain good protection of optical fiber. It is especially designed for harsh environments, and can be used for various applications, underwater, fire resistant, and anti-rodent facilities etc. It is suitable for the direct use or basis use or basic optical units of fiber cable.

Characteristics
Fire monitoring
Oil well exploration
Oil pipe monitoring and communication
Optical unit for multipurpose optical cable

Construction
Small size and low weight
Good mechanical performance, withstanding the tensile force and force and super pressure
Waterproof, moisture-proof, anti-rodents,no rusty
Resistance to acid, alkali, salt corrsion
Non-toxic, flame retardant, fire and explosion proof
Outstanding high and low temperature performances
With excellent fire resistance, it can keep communication in the fire(800ºC) more than 2 hours with normal optical fiber
