Abstract:
1. An optoelectronic transceiver with power voltage detection comprising: a light emitting device for transmitting an optical signal; a light detecting device for receiving an optical signal; a drive circuit for sending a transmission electrical signal to said light emitting device; an amplifier for amplifying a receiving electrical signal from said light emitting device; a signal processing circuit for processing the transmission and/or receiving electrical signal at the front stage of said drive circuit and/or amplifier; more than one different power supply for powering more than one circuit element in said optoelectronic transceiver; a power voltage supply timing detecting means for detecting the voltages of said more than one power supply and verifying that more than one predetermined power supply voltage are turned on; a first timer configured to output a first reset signal after a predetermined time period after the verification by said detecting means; a second timer configured to output a second reset signal after a predetermined time period after the verification by said detecting means; and a memory to output a storage information setting signal which sets a predetermined operation condition of said signal processing circuit, wherein said memory is configured to output said storage information setting signal subsequent to receiving said first reset signal, wherein said drive circuit transmits said transmission electrical signal to said light emitting device subsequent to receiving said second reset signal.
