    摘要: A high-speed optical transmitter comprises multiple digital lanes that are provided to a bank of digital-to-analog converters. The analog signals are then used to Phase Shift Keyed (PSK) modulation using a Chirp Managed Laser (CML)-based transmitter, and potentially using dual polarization. A corresponding optical receiver receives the sequence of optical signals at a demodulator. For each polarization, the demodulator includes a corresponding demodulation channel that is configured to demodulate that polarization component of the optical signal into one or more signal components. Each of these signal components is converted into a corresponding digital signal using a corresponding analog-to-digital converter. In the case of higher-order PSK modulation (e.g., 8PSK or higher), for each polarization, the analog converter has a lower sampling rate than for QPSK modulation.

    摘要: An optical transmitter that determines and controls the extinction ratio of an optical signal by modulating the duty cycle of the optical signal. The transmitter obtains a signal from the monitor circuit that represents optical power emitted by the electro-optic transducer during normal conditions in which the duty cycle of the optical signal is between a bias high and bias low modulation condition. The transmitter also obtains a signal from the monitor circuit that represents optical power emitted during the bias high modulation condition in which the time at the optical high power level in the eye diagram is greater. Also, the transmitter obtains a signal that represents optical power emitted by the electro-optic transducer during the bias low modulation condition in which the time at the optical low power level in the eye diagram is greater. Based on these signals, the transmitter then derives the extinction ratio.

    摘要: An optoelectronic assembly includes an optoelectronic device, housed in a transistor outline (TO) package having a base and a signal lead traversing an aperture in the base, and a circuit interconnect coupled to the optoelectronic device and TO package. The circuit interconnect substantially comprises an insulator, and includes a data signal trace, a resistor, and a conductor. The data signal trace, on a first side of the insulator, transmits data signal current between the optoelectronic device and an external device. The resistor, also on the first side, transmits the data signal current between the optoelectronic device and the data signal trace. The resistor is electrically and mechanically connected to the signal lead and to data signal trace. The conductor, on a second side of the insulator, transmits a ground current between the TO package and the external device, and forms a current path substantially parallel to the data signal trace.

    摘要: This disclosure is generally concerned with optical transceivers. In one example, an optical transceiver implements electronic dispersion compensation in the receive path, as well as optical preemphasis on the transmitted signal in order to improve aspects of optical performance on multimode fiber links, relative to systems that do not implement transmitter preemphasis. Among other things, such optical transceivers can be used to achieve longer link lengths over a given fiber and/or to improve the percentage of fibers that can be used with a given performance electronic dispersion implementation.
