Abstract: An apparatus having a plurality of multifiber connector interfaces, where some of these multifiber connector interfaces can connect to network equipment in a network using multifiber cables, has an internal mesh implemented in two tiers. The first is configured to rearrange and the second is configured to recombine individual fiber of the different fiber groups. The light path of each transmitter and receiver is matched in order to provide proper optical connections from transmitting to receiving fibers and complex arbitrary network topologies can be implemented with at least 1/N less point to point interconnections, where N=number of channels per multifiber connector interface.

Abstract: Apparatuses having a plurality of optical duplex and parallel connector adapters, such as MPO connectors and LC adapters, where some adapters connect to network equipment in a network and others to servers or processing units such as GPUs, incorporate internal photonic circuit with a mesh. The light path of each transmitter and receivers is matched in order to provide proper optical connections from transmitting to receiving fibers, wherein complex arbitrary network topologies can be implemented.

Abstract: Methods for estimating the Effective Modal Bandwidth (EMB) of laser optimized Multimode Fiber (MMF) at a specified wavelength, λS, based on the measured EMB at a first reference measurement wavelength, λM. In these methods the Differential Mode Delay (DMD) of a MMF is measured and the Effective Modal Bandwidth (EMB) is computed at a first measurement wavelength. By extracting signal features such as centroids, peak power, pulse widths, and skews, as described in this disclosure, the EMB can be estimated at a second specified wavelength with different degrees of accuracy. The first method estimates the EMB at the second specified wavelength based on measurements at the reference wavelength. The second method predicts if the EMB at the second specified wavelength is equal or greater than a specified bandwidth limit.

Abstract: An expanded beam connector has a MOST ferrule; a fiber to be retained within the MOST ferrule; and, a collimating lens abutting the fiber for expanding the optical beam of the fiber wherein the lens and fiber are in alignment to a common optic axis. In one embodiment, the collimating lens can have a conical cutout configured to aid in aligning the fiber to the common optic axis. In another embodiment, the collimating lens can have a semi-cylindrical tab protruding from the rear with a V-groove configured to interact with a flexible feature on the interior of the ferrule to align the fiber to the common optic axis.

Abstract: A method for evaluating the optical insertion loss of a mechanical splice joint of two optical fibers with a laser source includes, upon initiation by a user, automatically performing the steps of: checking for ambient light, estimating the level of noise by analyzing an area of a sensor that is not illuminated by external sources and setting a noise threshold, checking self-alignment by taking a foreground image of the joint with the laser source turned on and one with it turned off, subtracting the images to obtain a resultant image, setting all pixels with levels below the noise threshold to zero, selecting a region of interest of the joint, computing a centroid and a width of the resultant image based on the region of interest, estimating a tilt and if the tilt is above a certain threshold, compensating for the tilt, and processing the resultant image.

Abstract: A graded index multimode fiber and method of producing the graded index multimode fiber utilize a technique of reducing an index profile of the core of the multimode fiber below a standard parabolic index profile. This can be done by changing dopant concentrations in the fiber core over the radius of the fiber core. The result is a multimode fiber having differential mode delay characteristics that are intentionally not minimized. The index profile can be reduced below the standard parabolic index profile over the entire radius of the core, or only for radii above a specified radius.
