FAQ
1. Do you provide technical support for EDFA optical path design or polarization-maintaining link isolation assessment?
Absolutely. Our international R&D and engineering team has extensive technical expertise in polarization-maintaining optical communication and special wavelength division multiplexing (WDM). Whether it's complex wavelength isolation assessment, cascaded attenuation calculation of the end-to-end polarization extinction ratio (PER), or optical power budget optimization schemes, we can provide you with expert-level remote technical consultation via video conference or email.
2. What is the RMA (Return/Exchange) process if abnormal parameters are found during precision testing upon receipt?
We understand that core filtering components have a veto power over the signal-to-noise ratio of your fiber optic system, therefore we implement a transparent and extremely fast RMA response mechanism. If you find any extinction ratio deviation, insufficient isolation, or insertion loss abnormalities during testing, simply submit the test spectrum or data, and our senior engineers will conduct an online technical assessment within 24 hours. Once it is confirmed that the defect is due to a manufacturing defect, we will immediately initiate an expedited sampling, replacement, or return process to resolutely protect your project schedule and procurement rights.
