Japanese Patent JP3119246
Kind Code:
B2
Abstract:
An optical transmitter in which a light-emitter diode and a drive circuit for driving the light-emitter diode at the time of ordinary operation are mixed to be mounted, and which is capable of selecting the light emitting diode. A light emitting diode and a light emitting diode drive integrated circuit are mixed to be mounted on the inside of a package of the optical transmitter. An anode side of the light-emitting diode is connected to the power supply terminal for light-emitting diode to be applied constant voltage. Further, a cathode side of the light-emitting diode is connected to the terminal for constant current source. When the work for selection of the light emitting diode is implemented, current is supplied to the light-emitting diode from these positions. Consequently, the operation for the selection of the light-emitting diode becomes possible with the condition that the light-emitting diode drive integrated circuit is mixed to be mounted.
