Abstract: Circuitry (50) of an optical line terminal (OLT) (15) can be controlled to be compatible with optical modules (55) of different optical protocols having different electrical connectivity requirements. In some embodiments, the OLT has a controller (63) that is configured to communicate with an optical module (55) plugged or otherwise mated with a socket (51) of the OLT in order to discover a module type of the optical module. Based on the detected module type, the controller is configured to control the electrical characteristics of the OLT circuitry so that it is compatible with the electrical and operational requirements of the optical module. Thus, the OLT is compatible for use with any of a plurality of optical module types.

Abstract: An optical fiber termination system includes a housing, a cable, and a catch. The housing defines a portion of a passageway and a surface surrounding the passageway. The passageway defines a central axis and the surface defines an interior of the housing. The cable is receivable through the portion of the passageway. The cable includes an optical fiber and defines a longitudinal axis. The catch is receivable in the housing and attachable to and extendable from the cable in a direction transverse to the longitudinal axis such that the catch limits movement of the cable in a direction away from the interior of the housing when the catch is received in the housing and the cable is received through the portion of the first passageway.

Abstract: A system and method for efficient data transfer in a computing system are described. A computing system includes multiple nodes that receive tasks to process. A bridge interconnect transfers data between two processing nodes without the aid of a system bus on the motherboard. One of the multiple bridge interconnects of the computing system is an optical bridge interconnect that transmits optical information across the optical bridge interconnect between two nodes. The receiving node uses photonic integrated circuits to translate the optical information into electrical information for processing by electrical integrated circuits. One or more nodes switch between using an optical bridge interconnect and a non-optical bridge interconnect based on one or more factors such as measured power consumption and measured data transmission error rates.

Abstract: SyCOmmstems and methods for performing matrix operations using a linear photonic processor are provided. The linear photonic processor is formed as an array of first amplitude modulators and second amplitude modulators, the first amplitude modulators configured to encode elements of a vector into first optical signals and the second amplitude modulators configured to encode a product between the vector elements and matrix elements into second optical signals. The linear photonic processor may be configured to perform matrix-vector and/or matrix-matrix operations.
