Optical fiber composite low-voltage cable (OPLC) optical fiber cable and cable are integrated into one, "one cable simultaneous transmission" power flow and information flow, creatively compounding communication optical cable and power cable, realizing terminal power supply and information transmission Dual function. It is a cable that combines optical units in a low-voltage power cable and has power transmission and optical communication transmission capabilities. It is suitable for voltage ratings of rated voltages of 0.6/1.0kv and below.
Features and applications
● The cable part and the cable part are kept relatively independent structure, which is convenient for introduction, extraction and connection during installation;
● Photoelectric integrated transmission medium to avoid secondary wiring and save construction costs;
● Smart grid construction, fiber optic homes in urban residential quarters and buildings.
