Abstract: A device and method of optical equalization using an optical modulator is provided. An electrical modulation signal is split into a first modulation signal and a second modulation signal. The second modulation signal is delayed relative to the first modulation signal. An amplitude of the second modulation signal is attenuated relative to the first modulation signal. The first modulation signal is applied to a first waveguide segment of the optical modulator. The second modulation signal that is delayed and attenuated relative to the first modulation signal is applied to a second waveguide segment of the optical modulator. Both the applied first and second modulation signals generate a feed-forward equalized optical signal that is recombined in the optical domain.

Abstract: A method for transmitting data between a first device and a second device over a communication link includes transmitting, by the first device, data of a first type using one or more first channels, receiving, by the second device, the data of the first type from the first device using the one or more first channels, generating, by the second device, data of a second type based on the data of the first type, and transmitting, by the second device, the generated data of the second type using one or more second channels. The data of the first type and the data of the second type are different. The one or more second channels are channels dedicated to transmit the data of the second type.

Abstract: Methods an systems for low-power transmission include biasing an emitter in a non-linear operating range of the emitter near a threshold current of the emitter. A data signal is distorted to add a precursor pulse to a rising edge of a data waveform to quickly bring the emitter into a linear operating range. The distorted data signal is transmitted at the emitter.

Abstract: Tuning parameters of individual wavelength channels transmitted over a multimode optical fiber is provided. Characteristics of the multimode optical fiber used for an optical data link within an optical signal transmission system are retrieved. A wavelength channel grid including each central wavelength in a plurality of central wavelengths that corresponds to each particular wavelength channel in a plurality of wavelength channels used to transmit data via optical signals over the multimode optical fiber is determined. A maximum allowable data rate is calculated for each wavelength channel based on the characteristics of the multimode optical fiber at defined channel wavelengths, optical signal transceiver specifications, and data transmission performance requirements for the optical signal transmission system. Operational parameters are assigned to each wavelength channel based on the calculated maximum allowable data rate for each wavelength channel to achieve the data transmission performance requirements for the optical signal transmission system.
