Abstract
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.
