OPGW Optical fiber composite overhead ground wire
OPGW is an optical fiber composite overhead ground wire, referred to as OPGW optical cable. The optical fiber unit is put into the overhead ground wire, and the optical cable and the ground wire are organically combined. On the premise of ensuring the original electrical and mechanical properties of the overhead ground wire, information such as audio, video and data can be transmitted.
ADSS All dielectric self-supporting optical fiber cable
ADSS optical cable adopts loose-jacketed stranded structure. Single-mode or multimode optical fiber is jacketed into a loose tube made of high-modulus plastic, and the tube is filled with water-repellent compound. Loose tube (filling rope) is twisted around the central nonmetallic reinforcement (FRP) to form a compact circular cable core, the gap in the cable core is filled with water-blocking filler, and the cable core is twisted with a layer of aramid fiber for reinforcement, and finally a polyethylene sheath or an electric trace-resistant outer sheath is extruded.
GYTA Loose layer stranded aluminum-plastic sheath optical cable
The optical fiber is set into a high modulus loose tube made of polyester material. The tube is filled with waterproof compounds inside. The optical fiber has excess length, so that the optical fiber is unstressed. In the center of the cable core, there is a metal reinforced core. Loose tube and the gasket for packing are stranded into a compact circular cable core around the central reinforced core. The gap inside the cable core is filled with water-blocking filler, plastic coated aluminum band-polyethylene adhesive sheath optical cable.
