Fibers are positioned in a central loose tube made of high-modulus plastic and filled with tube gel. Then two parallel FRP are embeded. Finally a PE 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 non-metallic strength member （FRP) to form the cable core. Then the core is filled with water blocking yarns and longitudinally wrapped with water blocking tapes. The cable is completed with a PE outer jacket.

The fibers are positioned in a loose tube made of high modulus plastic and filled with gel. Tubes (and fillers) are stranded around the non-metallic strength member （FRP) to form the cable core. Then an aluminum tape (APL) is armored longitudinally around the cable core, which is filled with water blocking compound. Finally a PE jacket is extruded.
 

The The fibers are positioned in a loose tube made of high modulus plastic and filled with gel. Tubes (and fillers) are stranded around the non-metallic strength member to form the cable core. Then the core is filled with water-blocking compound and covered with a PE inner jacket. After the corrugated steel tape(CST) 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 to form a cable core. Then, a LSZH outer jacket is extruded.

Self-supporting drop optical cable includes central optical fiber(s) with 2 parallel FRPs as the strength members placed on both sides,and an additional strength member(steel wire). Finally a LSZH jacket is extruded outside.
