China GDTA53 Multi-mode Optical Fiber Manufacturer, Supplier, Factory

All dielectric self-supporting ADSS aerial fiber optic cable adopts loose tube layer stranding structure, and 250μm optical fiber is sheathed in loose tube made of high modulus material, and the loose tube is filled with waterproof compound. The loose tube (and filling rope) are twisted around the non-metallic center reinforcement core (FRP) to form a compact cable core, and the gap of the cable core is filled with water-blocking grease. The cable core is extruded with a polyethylene (PE) inner sheath, then covered with aramid for reinforcement, and finally extruded with a polyethylene (PE) outer sheath or an electric tracking (AT) outer sheath.

Waterproof fiber optic cable GJA uses single-core optical cable (φ900μm tight-buffered optical fiber, winding yarn as a reinforcing member) as a sub-unit, the center of the cable core is fiber reinforced plastic (FRP) as a non-metallic reinforcing member, the sub-units are twisted around the cable core, the cable core is covered with aluminum-polyethylene laminate, and the cable is covered with a polyethylene sheath.

The self-supporting fiber optic round drop cable is composed of a tight-buffered optical fiber, which is covered with high-strength aramid yarn, a metal reinforcement element is attached to the outside, and finally a layer of sheath material is squeezed on it.

The structure of figure 8 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 is a metal reinforcing core, and the loose tube (and filling rope) are twisted around the central reinforcing core to form a compact circular cable core. The cable core is longitudinally wrapped with a layer of plastic-coated aluminum tape (APL) and integrated with the steel wire strands into an 8-shaped polyethylene sheath.

MPO multi-fiber push-on fiber optic cable (MPO≥24f) uses 12 core units (Φ250μm colored optical fiber, aramid reinforcement elements), non-metallic central reinforcement core, the optical cable sub-units are twisted in the central reinforcement core to form a cable core, and a layer of polyvinyl chloride (PVC) or low smoke zero halogen material (LSZH, low smoke, halogen-free, flame retardant) sheath is extruded on the outside.

Hybrid optical and electrical stranded loose tube cable GDTA is housed in loose tubes made of high modulus plastic and filled with tube filling compound. At the center of the cable is a metal strength member. The tube and copper wire (required specification) are wrapped around the center strength member to form the cable core. The cable core is filled with cable filling compound and armored with laminated aluminum tape. A PE jacket is then extruded to form the outer jacket.
