  • Why is it difficult to leave excess fiber length in loose-tube optical cables

    Why is it difficult to leave excess fiber length in loose-tube optical cables

    Depending on the cable structure, this excess length is 0. The overlength protects the fiber in the event of bending stress or tension on the cable. These miniaturized stranded loose tube cables, with increased fiber counts per cross-sectional areas, could be installed with less cost and disruption than a rip-and-replace solution. However. Translations are not retained in our system. Balancing EFL and tube shrinkage requires a controlled. The method to calculate the excess fiber length in a stranded loose tube fiber optic cable is very easy. Excess fiber length can be defined as the additional physical fiber length as compared to the linear physical length of the loose tube in which the fibers are contained. This tension applied on the fiber is taken by the glass part of the fiber mainly as the strain bearing capacity of silica is higher than the acrylic coating.
