Optical communication apparatus and control method thereof

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