  • Patent number: 9331781
    Abstract: A digital burst mode communication system operates at a fixed wavelength for transmission and reception of burst mode signals using a pair of transceivers and a single optical cable. The stray noise level in the system is significantly reduced by use of angled plate absorbers that receive scattered transmission burst signal from a 45 degree partially reflecting mirror. Use of transparent glass ferrule with or without a front surface anti-reflection coating instead of an opaque ceramic ferrule to support optical fiber at a selected location within the transreceiver reduces optical detector signal noise. Isolation of received burst signal from transmitted burst signal is increased to better than 30 dB. The system operates by sending only data bits across the single optical cable without scrambling or encoding preambles, significantly improving the efficiency of high speed communication.

    Abstract: An information handling system (IHS) selectively performs duty-cycled equalization of data transmission on a communication link between a sending component and a receiving component. A controller activates an equalizer associated with the communication link.

If power consumption and/or data throughput do not exceed respective specified threshold values, the controller maintains or applies continuous equalization.

  • Patent number: 9036994
    Abstract: The invention provides optical interconnects of data-processing cores of multicore chips by means of digital planar holographic microchips. The method comprises delivering “N” laser lights to “N” data-processing cores on the host chip, coding the obtained optical signals by modulating them with the core-generated data, and then delivering the modulated and coded optical signals to a holographic microchip formed on the same substrate of the host chip as the data-processing cores, splitting the modulated and coded optical signals into (N?1)N modulated optical copy signals, delivering the copy signals to all data-processing cores except the one that generates the copy signals, and decoding the data obtained from the output signals delivered to the processing cores by the receivers. The method is efficient in that it allows replacing electrical interconnects between the cores with optical interconnects and can be matched to current semiconductor production technology.
