Title:
TRANSMISSION INTERFACE AND TRANSMISSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/203058
Kind Code:
A1
Abstract:
This transmission interface (10) having a plurality of transmitters (101_1 to 101-N), wherein the transmitters are provided with: a power supply terminal (151) shared by the plurality of transmitters, to which a ground voltage is inputted; a bias terminal (152) to which a bias voltage is inputted; signal terminals (153_1 to 153_N) to which a signal voltage is inputted; a power supply change-inverted bias unit (111) to which a ground voltage and a bias voltage are applied, and which outputs the ground voltage making its change 180 degrees out of phase; a modulation unit (13) to which the output of the power supply change-inverted bias unit and a signal voltage are applied, and which outputs the opposite-phase ground voltage making its change in phase; and a laser diode (14) to which the ground voltage and the output of the modulation unit are applied. The present invention is thereby made possible to provide a transmission interface that suppresses a change of the voltage applied to the laser diode.
