    Abstract: A transducer reliability testing and VCSEL failure prediction method are provided. The method includes applying a testing temperature and a constant current to a VCSEL for a testing time. The method monitors a forward voltage of the VCSEL and determines if a first change in forward voltage is above a first predetermined threshold over the testing time and if a second change in forward voltage is above a second predetermined threshold over a portion of the testing time. The method determines failure of the VCSEL if either of these predetermined thresholds are exceeded. The method determines passage of the VCSEL if the first change in the forward voltage and the second change in the forward voltage are both below the first predetermined threshold and the second predetermined threshold, respectively.

    Abstract: An electro-optic transceiver module, method of manufacturing, and method of transmitting signals are provided that allow multiple optical signals at different wavelengths (e.g., according to CWDM) to be combined for transmission via a number of optical fibers that is smaller than the number of electrical channels according to which the optical signals were generated. Thus, CWDM may be used in connection with lower-cost VCSEL technology (e.g., as opposed to higher-cost edge-emitting lasers) by providing for wavelength compensation at the VCSEL driver to offset any changes in wavelength that may have otherwise occurred at the VCSELs. In particular, a microcontroller of the electro-optic transceiver module correlates a monitored temperature of the VCSELs to an actual wavelength of the corresponding optical signals transmitted by the respective VCSELS and determined an adjustment in a current supplied by the VCSEL driver to each VCSEL to achieve more precise and consistent wavelengths at the VCSELs.

    Abstract: A reconfigurable and redundant electro-optical connector and corresponding method are provided. The connector may include a first plurality of transducers in communication with a first port and a second plurality of transducers in communication with a second port, the first port and the first transducers defining a first channel and the second port and the second transducers defining a second channel. The connector may include a selective combiner to combine the first optical signals and the second optical signals, and a controller in communication with each of the transducers. The controller may transmit at least a first portion of a first datalink on at least the first channel in a first configuration. The controller may redistribute the first portion of the first datalink onto at least the second channel in a second configuration.

    Abstract: A switching device includes a plurality of ports and a switching core, which is coupled to transfer data packets between ingress and egress ports. Switching logic maintains a descriptor queue containing respective descriptors corresponding to the data packets that have been received and queued by the ports, and responsively to the respective descriptors, instructs the switching core to transfer the queued data packets between the ports. Port logic, which is associated with each port, is configured, upon receipt of a data packet from the network at the port, to signal the switching logic to place a descriptor corresponding to the data packet in the descriptor queue and, upon identifying the data packet as meeting a predefined criterion, to convey a request to the switching logic, bypassing the descriptor queue, to instruct the switching core to transfer the data packet immediately to an egress port.

    Abstract: An apparatus includes multiple data sources and arbitration circuitry. The data sources are configured to send to a common destination data items and respective arbitration requests, such that the data items are sent to the destination regardless of receiving any indication that the data items were served to the destination in response to the respective arbitration requests. The arbitration circuitry is configured to receive and buffer the data items, to perform arbitration on the buffered data items responsively to the arbitration requests, and to serve the buffered data items to the destination in accordance with the arbitration.

    Abstract: An opto-mechanical coupler and corresponding method are provided. The coupler may include a first end and a second end configured to receive optical fibers and a top surface and bottomed surface defining a through hole extending between the top and bottom surfaces. The coupler may include a reflective surface that redirects the optical signals between a first direction and a second direction substantially perpendicular to the first direction. The coupler may position one or more optical fibers along a second direction such that an optical signal from the plurality of optoelectronic transceivers is directed into one or more optical fibers or an optical signal from the one or more optical fibers is directed into a plurality of the optoelectronic transceivers, with the coupler accommodating different diameters of optical fiber including POF, SMF, and/or MMF fiber.
