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 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.

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.
