摘要： The present disclosure provides a COMBO optical module circuit, including a MCU control circuit, a first optical transmission circuit, and a second optical transmission circuit. The MCU control circuit includes three control units. A first control unit (U1) is configured to determine a transmission channel according to a signal level. A second control unit (U7) is configured to switch between a TX_SD_10G signal and a TX_SD_1G signal. A third control unit (U2) is configured to realize a slow start function of an optical module, and is further configured to supply power to the second optical transmission circuit circuit using PWR_1G control or the first optical transmission circuit circuit using PWR_10G control. The first control unit (U1) is further configured to control the first optical transmission circuit through a first serial clock port (SCL_10G) and a first serial data port (SDA_10G) in an inter integrated circuit (I2C) communication mode, or control the second optical transmission circuit through a second serial clock port (SCL_2.5G) and a second serial data port (SDA_2.5G) in the I2C communication mode, or control the second optical transmission circuit through a third serial clock port (SCL_1G) and a third serial data port (SDA_1G) in the I2C communication mode. The first optical transmission circuit is configured to receive and emit a first rate optical signal according to the control of the first control unit. The present disclosure reduces complexity of optical signal transmission.

摘要： An extinction ratio testing system (10) includes a microcontroller (102), an extinction ratio tester (104), and a thermostat (106). The microcontroller (102) controls the thermostat (106) to maintain an optical transceiver module (20) at a predetermined high temperature, and then the microcontroller (102) controls the extinction ratio tester (104) to test an extinction ratio of the optical transceiver module (20). If the extinction ratio is lower than a standard extinction ratio, the microcontroller (102) controls the optical transceiver module (20) to increase a laser operating current (212) of the optical transceiver module (20) to increase the extinction ratio.
