摘要： An optical transmission apparatus is disclosed which comprises a light emitting element for outputting an optical output in order to transmit data, a current modulation circuit, a bias current generating circuit and a resistor circuit connected in parallel with the emitting element. The current modulation circuit supplies a binary modulated current to the emitting element in response to an input binary data to the transmitted, the bias current generating circuit provides a bias current to the emitting element and the resisor circuit, whereby said bias current is kept higher than a specified level.
