Composite Optical Fiber Cable

Description
Composite optical fiber cable is made up of a cable section and the optical cable section. It is suitable for use as a transmission line of the broadband access network system. That is a new kind of access method which can solve the problems of broadband access, electricity using of equipment and signal transmission.

Standard
The structure of composite optical fiber cable is to combine the fiber optic whose radius is 250μm inside the loose tube which is made of high modulus materials. And the loose tube is filled with waterproof compound. In the center of the cable core is a FRP or a metal reinforcement which can be added with a PE cushion according to our clients' requirements. The wire and loose tube strand the central strength member to form a compact and round cable core. The waterproof fillers fill up the gap inside the cable core. The APL is longitudinally wrapped and sheathed with polyethylene or LSZH to form the cable.

Features Photoelectric mixing and the integration of optical cable and photoelectric save the pipeline resources effectively. The cable section and the optical cable section remain relatively independent structure which can be convenient for the lead-in, lead-out and connection while installing. Photoelectric mixing realizes the multi-network of power cable, telephone line, TV cable, network cable, monitoring cable, data cable and so on which saves on cost. The diameter and radius of the fiber optic cable is small so that it can be installed freely in small spaces. In the meantime, the composite optical fiber cable is compatible with optical signal transmission and power transmission. The range of the composite optical fiber cable's operating and constructing temperature is relatively large. The composite optical fiber cable has great mechanical behavior and temperature characteristic.
