Indoor cable heat shrinkable tube is fiber heat shrinkable tubes do
The heat shrinkable tube is composed of a transparent heat shrinkable tube, a hot melt pipe and a stainless steel needle (or ceramic rod / quartz rod).
The transparent outer layer facilitates the detection of optical fiber joint connection is correct, the fiber can safe and easy to assemble, the contraction can keep the optical transmission characteristics of optical fiber, optical fiber joint to provide strength and protection, to avoid damage to the fiber during the installation process.
Not exactly, because the model includes not only include optical fiber, cable and other wire, it is called the wire tube.
