Abstract: Embodiments of the present invention generally relate to the field of fiber optic communication, and more specifically, to optical time domain reflectometer apparatuses used for testing the integrity of a communication channel. Due to its high bandwidth, low dispersion, low attenuation, and immunity to electromagnetic interference among other advantages single-mode and multimode optical fibers are the standard transmission media used for intermediate and long reach high-speed communication applications in data centers, enterprise networks, metropolitan area networks (MANs), and long haul systems. Optical channels often contain other passive elements such as optical connectors, adapters, patch cords, splitters, combiners, and filters.

Abstract: A multi-channel, multi-port 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 guides of the first array.

Abstract: A method for compensating for both material or chromatic dispersion and modal dispersion effects in a multimode fiber transmission system is provided. The method includes, but is not limited to measuring a fiber-coupled spatial spectral distribution of the multimode fiber laser transmitter connected with a reference multimode fiber optical cable and determining the amount of chromatic dispersion and modal dispersion present in the reference multimode fiber optic cable. The method also includes, but is not limited to, designing an improved multimode fiber optic cable which compensates for at least a portion of the chromatic dispersion and modal dispersion present in the reference multimode fiber optic cable resulting from the transmitter's fiber-coupled spatial spectral distribution.
