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. | ℃ | 41.5 | 42.4 | 0.9 | pass |
Vcc | V | 3.33 | 3.34 | 0.01 | pass |
