Abstract: This disclosure provides systems, methods, and apparatus for an energy efficient communication system. The communication system can include a transmitter, a receiver and a communication link for communicating data between the transmitter and the receiver. In some implementations, the receiver determines a signal quality parameter (SQP) value of the received data, and communicates the SQP value to the transmitter. In some implementations, the transmitter adjusts one or more operational parameters of the transmitter to reduce power based on the received SQP value being less than a threshold value. In some implementations, the receiver also adjusts one or more operational parameters of the receiver based on the SQP value being less than a threshold value. In some implementations, the receiver can communicate the SQP value to the transmitter over out-of-band communication links.

Abstract: An optical communication apparatus includes a variable resistor unit, a measurement unit, and a control unit. The variable resistor unit is arranged at a pre-stage of an electrical/optical conversion unit, which converts an electrical signal obtained by converting an input packet to an optical signal having a waveform corresponding to a potential difference between a positive phase component and a negative phase component of the electrical signal by using the potential difference. The variable resistor unit provides a resistor that varies a midpoint of potential of the positive phase component or the negative phase component. The measurement unit measures a ratio of a presence period, which is a period where the input packet is present, to a sum of the presence period and a non-presence period. The control unit controls a value of the resistor provided to the positive phase component or the negative phase component based on the ratio.
