An optical fiber cable includes a cable jacket, a plurality of buffer tubes arranged on the inside of the cable jacket, a plurality of optical fibers arranged on the inside of each buffer tube, and a fire-retardant material having intrinsic tire-retarding properties. The fire-retardant material may be a filling material disposed between the cable jacket and the buffer tubes.

Optical fiber cable and method of forming an optical fiber cable

A micromodule cable having optical transmission elements arranged in a helically wound manner around a longitudinal axis by at least 360&#xb0; in a longitudinal direction where the lay length is 100 times of the diameter of the optical cable. The cable is stable across a wide temperature range.

Optical cable

An optical transmission element comprises a core section including a plurality of optical fibers where each one of the optical fibers is in contact with at least two other optical fibers. The optical transmission element also has a sheath section including a sheath layer surrounding the core section such that the sheath layer is in contact with the optical fibers.

Optical transmission element

An optical cable comprises a tight-buffered optical cable and a protective sleeve which surrounds the tight-buffered optical cable. An intermediate layer surrounds the protective sleeve has tension-resistant elements. Furthermore, the optical cable contains a cable sheath which surrounds the intermediate layer, and a transitional area facing its inner surface. In this transitional area, the material of the cable sheath is mixed with the tension-resistant elements of the intermediate layer.

Optical cable and method for producing an optical cable

An optical cable comprises a plurality of elongate members wherein at least one of the elongate members include at least one optical fiber surrounded by buffer tube. The buffer tube is made of a soft material having a tension at break of less than 7.5 MPa. The elongate members are disposed around a central element. A binder is wrapped around the plurality of elongate members. An outer jacket surrounds the plurality of elongate members.

Optical cable with stranded micromodules

An apparatus and a method for forming a sheath over an elongate member comprises an extruder that has an output to supply a melt material having a temperature. A heat exchanger connected downstream the output of the extruder removes heat from the melt material in a controlled manner. An elongate member, which may be a cable core, is supplied to a crosshead that is connected downstream the heat exchanger to surround the elongate member with a sheath of the melt material.

Apparatus for forming a sheath over an elongate member, extruder system and method of manufacturing a fiber optic cable

An optical cable comprises a swelling yarn, around which several optical transmission elements in the form of micromodules are arranged. A micromodule comprises a bundle of optic fibers, which are surrounded by a sleeve made from a material of plastic. Further swelling yarns are arranged around the optical transmission elements. The optical transmission elements and the swelling yarns are surrounded by a sleeve of paper. The paper sleeve is surrounded by a cable jacket made from a material of plastic. When an optic fiber is exposed, the cable jacket is pulled off, whereupon the paper sleeve tears off and can consequently be easily removed.
