Photoelectric Composite Fiber Optic Cable

The structure of the Tanghu opto-electric hybrid cable is to insert a 250μm fiber into a loose tube made of high-modulus material, and the loose tube is filled with a waterproof compound. The center of the cable core is FRP or metal reinforcement (some structures require a layer of PE underlay on the reinforcement). The wire and the loose tube (and the filling rope) are twisted around the central reinforcing core into a compact and round core, and the gap in the core is filled with a water blocking filler. The double-coated plastic strip (PSP) is longitudinally extruded and extruded into a polyethylene or low-smoke halogen-free (LSZH) jacket.

Features

 Has good flexibility and mechanical properties.

Photoelectric integration, fully saving pipeline resources.

The cable section and the cable section maintain a relatively independent structure for easy introduction, extraction and connection during installation. · Consolidate multiple power lines, telephone lines, TV lines, network lines, monitoring lines, data lines, etc., saving costs.

Large operating temperature range.

Large construction temperature range.

The diameter of the cable and the bending radius are small, and the colleague-compatible optical signal transmission and power transmission can be freely installed in a small space
