China Pre-terminated Round Drop Cable Manufacturer, Supplier, Factory

The structure of uni-tube non-armored fiber optic cable is to put 250μm optical fiber into a loose tube made of high modulus material, and the loose tube is filled with waterproof compound. Water-blocking material is added to the loose tube to ensure the longitudinal water-blocking of the optical cable. Two parallel steel wires are placed on both sides and then a polyethylene sheath is extruded to form a cable.

The hybrid optical and electrical stranded loose tube cable GDTA53 is sheathed in a loose tube made of high modulus plastic and filled with fillers. The center of the optical cable is a metal reinforcement core. The tube and copper wire (required specifications) are twisted around the central reinforcement core to form a cable core. The cable core is filled with optical cable fillers and armored with laminated aluminum tape, then a PE inner sheath is extruded and armored with corrugated steel tape, and finally a PE outer sheath is extruded.

The structure of stranded loose tube armored fiber optic cable is to put 250μm optical fiber into a loose tube made of high modulus material, and the loose tube is filled with waterproof compound. The center of the cable core is a metal reinforcement core. For optical cables with certain cores, a layer of polyethylene (PE) needs to be extruded outside the metal reinforcement core. The loose tube (and filling rope) are twisted around the central reinforcement core to form a compact and round cable core, and the gaps in the cable core are filled with water-blocking fillers. A layer of polyethylene inner sheath is extruded outside the cable core, and a double-sided plastic-coated steel tape (PSP) is longitudinally wrapped and then extruded into a polyethylene sheath to form a cable.

The simplex fiber optic cable uses a single Φ900μm or Φ600μm tight-buffered optical fiber as the optical transmission medium, covered with a layer of aramid as a reinforcement, and extruded with a layer of polyvinyl chloride (PVC) or low-smoke zero-halogen material (LSZH, low-smoke, halogen-free, flame-retardant) sheath.

Uni-tube optical fibre composite overhead ground wire (OPGW) is an overhead hybrid cable containing optical fiber, which has multiple functions such as overhead ground wire and optical communication.

Single-mode optical fiber G.654.E has lower attenuation or larger optical fiber effective area, which can help the system meet the 3U (ultra-high speed, ultra-large capacity, and ultra-long distance) characteristics.
