Optical fiber composite stainless steel loose tube

·Products 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 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.
