Fibers are housed in a central tube made of high-modulus plastic and filled with tube gel. The tube is armored with aramid yarns and water blocking yarns. Then the corruagted steel tape (CST ) is enhanced around the tube. Finally a PE jacket is extruded.

The fibers are positioned in loose tubes that are made of high-modulus plastic and filled with tube gel. The tubes (and fillers) are stranded around a metallic central strength member to form a cable core, which filled with water blocking compound. Then the core is armored with corrugated steel tape( CST) . Finally, a LSZH outer jacket is extruded
 

The fibers are positioned in loose tubes that are made of high-modulus plastic and filled with tube gel. The tubes (and fillers) are stranded around a non-metallic central strength member to form a cable core. Then, a LSZH outer jacket is extruded.
 

The fibers are positioned in a loose tube made of high modulus plastic and filled with gel. Tubes (and fillers) are stranded around the metallic strength member to form the cable core. An Aluminum tape(APL) is applied around the core, which is filled with the water-blocking compound. Then the cable core is covered with a PE inner jacket. After the steel tape is longitudinally armored over the inner jacket, the cable is completed with a PE outer jacket.

The fibers are positioned in loose tubes that are made of high-modulus plastic and filled with tube gel. The tubes (and fillers) are stranded around a non-metallic central strength member(FRP) to form a cable core. The core is filled with water-blocking compound and armored with laminated Aluminium tape(APL) . Stranded steel wires are applied as the messenger. Finally, a figure-8 PE outer jacket is extruded.

Optical fibres are housed in loose tubes that are made of high-modulus plastic and filled with tube filling compound. The tubes (and fillers) are stranded around a non-metallic central strength member to form a cable core. The gap of core is filled with water-blocking yarns or longitudinally wrapped with water-blocking tape. Then a LSZH outer jacket is extruded.
