Structure of GDTS optical fiber composite cable Optical fiber Gel: water proof compounds The buffer tuber: thermoplastic material Optical unit Central strength member: phosphatized steel wire, high-count fiber cable and extruded polyethylene Power feeder Water blocking material: water blocking filling compound Armored layer: steel-plastics tape The outer jacket: black polyethylene Description of GDTS optical Fiber Composite Cable

The structure of optical fiber composite cable is made by inserting 250m of optical fiber into a buffer tube made from high modulus polyester material. The buffer tuber is filled with filled with water proof compounds. The center of cable core is fiber reinforced plastics (FRP) or metallic strength core (metallic strength core with a layer of polyethylene). The electric wire and buffer tuber (and filling rope) is twisted around the central strength core to form a compact circular core, whose cracks are filled with water blocking materials. Extruded polyethylene or halogen-free sheath into cable after double plated plastic steel tape vertical wrapped.

Application of GDTS optical fiber composite cable

The optical fiber composite cable is suitable for short distance transmission and remote power supply for communication device.

Features
The diameter and bending radius of the optical fiber composite cable is small. So the optical fiber composite cable can also be installed freely in a small space and compatible with both optical signal transmission and electric power transmission. This product has great flexibility and machinery performance. This cable uses photoelectric integration and save pipeline resources fully. The part of power and optical cable remain relatively independent to make the installation easy when the introduction, extraction and connection. When we make the optical fiber composite cable, we integrate power lines, telephone lines, TV lines, network lines, monitoring lines, data lines, etc to save cost. This product has large range of operating temperature and construction temperature. Installation
