Q&A
Question
1. I don't know the exact split ratio, can you provide me the right PM coupler according to the insertion loss?
Answer1, Yes, we can provide you the right PM coupler with your insertion loss.
2. I don't want to choose the slow axis as my working axis, can I choose the fast axis as my working axis for my project?
Answer2, It's OK for us to make the special PM coupler.
3. Is it the same value for the actual insertion loss and the insertion loss on the test report?
Answer3, No, the insertion loss on our test report exclude the 3dB width band.
For other question about our PM coupler, you can contact our sales directly.
