Optical Fiber Composite Low-voltage Cable (OPLC) integrates optical cable and cable, "one cable simultaneous interpretation" power flow and information flow, creatively combines communication optical cable and power cable, and realizes the dual functions of terminal power supply and information transmission. It is a kind of cable that combines the optical unit in a low-voltage power cable and has the ability of power transmission and optical communication transmission, and is suitable for voltage levels with rated voltage of 0.6/1.0kV and below.
Features and applications
●The cable part and the optical cable part maintain a relatively independent structure, which is convenient for the introduction, introduction and connection during installation;
●Photoelectric integrated transmission medium, avoiding secondary wiring, saving construction costs;
● Smart grid construction, fiber-to-the-home for urban residential quarters and buildings.
