Abstract: A multi-channel, multi-port bi-directional optical tap coupler with an alignment base element, a pair of sub-assemblies located at opposite ends of the alignment base element, focusing elements located next to each sub-assembly, and an optical filter adjacent to, and in-between the focusing elements is described. The first sub-assembly has an array of waveguides with each waveguide having a radial offset and an azimuthal position with respect to a center axis of the array. The first array includes transmission waveguides and receiving waveguides and each receiving waveguide has a corresponding transmission wave guide that is separated by an azimuthal angle of 180 degrees. The second sub-assembly has a second array of waveguides including a wave guide having the same radial offset and the same azimuthal position for each of the transmission wave and receiving guides of the first array.

Abstract: Methods for designing improved multimode fiber optic cables are provided. In an embodiment, the method includes measuring a DMD waveform profile of a reference multimode fiber optic cable, where the reference multimode fiber optic cable has a reference refractive index profile. The method of this embodiment further includes designing an improved refractive index profile for the improved multimode fiber optic cable, where the improved refractive index profile comprises the reference refractive index profile modified by a quantity Δn(r), where r is a radius from the center of the core, where the quantity Δn(r) is negative over at least some radial window, and where the quantity Δn(r) follows a function such that the improved multimode fiber optic cable having the improved refractive index profile produces a DMD waveform profile having a shift to the left in radial pulse waveforms for increasing radii.
