Bend-insensitive multimode fibers (BI-MMF), first introduced in 2009, were developed to mitigate link failures when optical cables undergo small diameter bends, particularly in jumper and module applications in data centers. These are technically complex optical fibers in which the multimode core, or “waveguide,” of the fiber has been altered to improve macro-bend performance. Making changes to the waveguide impacts
many other fiber properties that must be optimized.|Bend-insensitive multimode fibers (BI-MMF), first introduced in 2009, were developed to mitigate link failures when optical cables undergo small diameter bends, particularly in jumper and module applications in data centers.
