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.
