之前的邮件已经讨论过，如下。3dB modulation loss是包

Mail has been discussed before, as follows. 3dB modulation loss is to include not connected VEA VEA set to the optimum power loss. Never take VEA VEA = 0V to the power loss of about 1.2dB, so that if the test conditions are changed to VEA = 0V, the output power needs to be reduced 1dB. <br>Further, the range of industrial products TE is generally ± 1.5dB, but XGS- TX TO actually used is with the TEC, TE TO itself better, so QOSA the TE can be controlled within ± 1dB, and according to our experience debugging module is typically about ± 0.5dB. <br>at present, our debug module is in the light of this specification, also learned that other companies are also defined in this way, you can also share the results of your debugging module to us.

The previous e-mail has been discussed, as follows. 3dB modulation loss is the optimum power loss that includes no VEA to VEA tuning. The power loss from never-connected VEA to VEA-0V is approximately 1.2dB, so if the test condition changes to VEA-0V, the output power needs to be reduced by 1dB.<br>In addition, the industrial-grade product TE range is generally 1.5dB, but because XGS-TX actually uses THE TO is with TEC, TO itself TE is better, so QOSA TE can be controlled within the range of 1dB, according to our module debugging experience value is usually about .5dB.<br>At present, our module is in this light specifications for debugging, at the same time understand that other companies are also defined, you can also share your module debugging results to us.

The previous email has been discussed as follows. 3dB modulation loss includes the optimal power loss from not connecting to VEA to adjusting to VEA. The power loss from never connected VEA to VEA = 0V is about 1.2dB, so if the test condition is changed to VEA = 0V, the output power needs to be reduced by 1dB<br>In addition, the te range of industrial products is generally ± 1.5dB, but because xgs-tx actually uses to with TEC, the te of to itself is better, so the te of qosa can be controlled within ± 1dB, and the experience value of debugging according to our module is generally about ± 0.5dB<br>At present, our module is debugged under this light output specification. At the same time, we know that other companies also define it like this. You can also share your module debugging results with us.
