Abstract: A test apparatus has at least one optical source, a high-speed photodetector, a microcontroller or processor, and electrical circuitry to power and drive the at least one optical source, photodetector, and microcontroller or processor and for measuring the frequency response of a multimode optical fiber under test. The test apparatus can utilize an optical pulse waveform with a light adapter to measure of the channel under test. It can also uses a correction method to de-embeed a chromatic bandwidth of the source from the encircled flux modal chromatic bandwidth. The correction method can use correction functions obtained for different type of VCSELs to estimate the optical channel bandwidth when used with VCSEL transceivers.

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.

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.
