Multimode Optical Fiber Insensitive to Bending Losses

摘要

A method of selecting a multimode optical fiber includes determining a first modal bandwidth value BW for each of a plurality of multimode optical fibers in a straight position and determining a second modal bandwidth value bBW for each of a plurality of multimode optical fibers in a bent position. Typically, the method includes selecting the multimode optical fibers for which the second modal bandwidth value bBW is greater than a threshold bandwidth A. The threshold bandwidth A may be (i) a function of the multimode optical fiber's first modal bandwidth value BW and a bending-loss value BL and (ii) greater than the multimode optical fiber's first modal bandwidth value BW.
