Fibers are positioned in a loose tube that is made of high-modulus plastic and filled with tube filling compound. The water blocking tape is applied around the central tube. Then the tubes are armored with a corrugated steel tape (CST) logitudinally. Two parallel steel wires are embeded in LSZH jacket.
 

                                  G.657 A1 BENDING INSENSITIVE SINGLE-MODE OPTICAL FIBER
 
Bending-loss insensitive single-mode optical fiber bears the entire characteristics of non-dispersion shifted single-mode optical fiber and superior bending performance, which is applicable to transmission over entire wavelength from 1260 nm to 1625 nm. Under the condition of long wave band, the bending radius could be as small as 10mm.
 

Fibres are housed in a loose tube that is made of high-modulus plastic and filled with tube gel. The tubes are armored with a corrugated steel tape (CST) logitudinally. Between the steel tape and the loose tube water-blocking material is applied to keep the cable compact and water-tight. Two parallel steel wires are embeded in the LSZH 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, filled with water blocking compound. 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 filled with water blocking compound. Then the steel tape (CST) is longitudinally armored over the cable core and covered with a thin PE inner jacket. After the steel tape is armored over the inner jacket, the cable is completed with a LSZH outer jacket.

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.
