  • Fiber optic circuit breaker
    Patent number: 10439733
    Abstract: An optical circuit breaker includes a main optical transmission path including an optical coupler, a delay line and a protection device, and a parallel protection path configured to receive a tapped portion of a signal provided to the main optical transmission path and generate a reference signal based on the tapped portion. The protection device may be configured to be triggered to prevent an overpower condition from passing through the optical circuit breaker responsive to the reference signal exceeding a user selectable threshold. The delay line may be configured to have a longer delay than a time it takes for the protection device to be triggered via the parallel protection path.
    Type: Grant
    Filed: January 8, 2015
    Date of Patent: October 8, 2019
    Assignee: The Johns Hopkins University
    Inventors: Joseph E. Sluz, Michael L. Dennis, Eric J. Adles, Raymond M. Sova, Chun-Huei Bair, Darrell A. Zinn, Edward H. Darlington

  • Cueing system for universal optical receiver
    Patent number: 8971701
    Abstract: A universal optical receiver may include an optical channel monitor configured to acquire spectral data for an optical signal on at least one selected optical channel, a tunable local oscillator configured to be tuned to a center frequency of the optical signal on the at least one selected optical channel, a storage device configured to store data associated with the optical signal responsive to acquisition of the spectral data and tuning of the tunable local oscillator, and processing circuitry configured to execute an algorithm that employs a plurality of binary distinctions based on physical characteristics of the optical signal and employs at least one calculation of figure of merit associated with a series of parameter values of the optical signal to identify a format of the optical signal.
