No. | Test Items | Test Results | Remark |
1 | Electric eye diagram test | PASS | |
2 | DOM test | PASS | |
3 | Power consumption test | PASS | |
4 | BER Test | PASS | *Streaming for 24 hours with 1G-Bert BER tester |
Test environment:
At room temperature, the BER tester sends codes (rate 1.25G, code type prbs23), and the optical/electrical eye diagram of the module is tested on the oscilloscope;
The optical eye diagram waveform is as follows

Test environment:
At room temperature (18~25°C), power on the sample module on the test fixture and work on the self-loop for half an hour and then test after the temperature stabilizes;
Test Results:
Symbol | unit | Actual_value | DMI_value | Delta | Decision |
Temp. | ℃ | 53.3 | 52.7 | 0.6 | pass |
Vcc | V | 3.33 | 3.31 | 0.02 | pass |
Bias | mA | 23.6 | 23.33 | 0.27 | pass |
TxPower | dBm | -5.5 | -5.92 | 0.42 | pass |
RxPower | dBm | -15.1 | -14.52 | 0.58 | pass |
Test environment
Make the module work at the ambient temperature of 0/25/70°C; record the current and voltage values after the temperature is stable, and calculate the power consumption;
Test Results:
Case Temp. | Vcc (V) | Icc (mA) | Dissipation( W) | Decision |
