Description
● Optical Fiber Composite Stainless Steel Loose Tube Cable:
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 from oil well to military, 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.
● Features:
►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 corrosion;
►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 (800℃) more than 2 hours with normal optical fiber.
● Application:
►Fire monitoring;
►Oil well exploration;
►Oil pipe monitoring and communication;
►Optical unit for multipurpose optical cable.
