Multimode optical fibers selection method for transmission system, involves selecting fibers, where modal bandwidth and value of bandwidth are function of predetermined bending loss

摘要

The method involves determining value of modal bandwidth (100) in a state where a multimode optical fiber is not subjected to bending. A determination is made (101) to find whether another value of the modal bandwidth in the state where the fiber undergoes curvatures. A set of fibers for which the latter value is greater than a bandwidth threshold is selected (102), where the modal bandwidth and the value of the bandwidth are function of predetermined bending loss. An independent claim is also included for a multimode optical fiber comprising a central core.
