Abstract : Fiber excess length is an important design factor in a loose tube cable, essential to the cable's optical and mechanical performance. It has been found that fiber excess length can change dramatically in the manufacturing process. One such change occurs at the point of winding the tube onto a bobbin under tension. There exists a difference between the excess length of an unstressed tube and that of a stressed (wound) tube. In this study, the effects of stress relaxation, temperature and bending on the manufactured tube are examined both theoretically and experimentally in the lab and in the field. (Author)
