Patent ID: 8891074

Claim:
A method of selecting a multimode optical fiber, comprising: providing a plurality of multimode optical fibers; for each multimode optical fiber, determining a first modal bandwidth value BW for the multimode optical fiber as positioned (i) with a minimum bend radius of 100 millimeters or more and (ii) under a tension of less than 50 grams-force (gf); for each multimode optical fiber, determining a second modal bandwidth value bBW for the multimode optical fiber as positioned (i) with a minimum bend radius of less than 100 millimeters and/or (ii) under a tension of 50 grams-force (gf) or greater; and selecting a multimode optical fiber that has a second modal bandwidth value bBW that is greater than a bandwidth threshold A, wherein (i) the bandwidth threshold A is a function of the multimode optical fiber's first modal bandwidth value BW and a bending-loss value BL and (ii) the bandwidth threshold A is greater than the multimode optical fiber's first modal bandwidth value BW.
