FAQ
1. Do you provide technical support for 400G/800G optical path design or O-band dispersion evaluation?
Absolutely.
2. What is the RMA (Return and Exchange) process if abnormal parameters are found during precision testing upon arrival at the warehouse?
We understand that the yield rate of core optical interfaces has a veto power over your high-speed optical transceiver modules; therefore, we implement a transparent and extremely fast RMA response mechanism. If you discover any center wavelength drift, abnormal extinction ratio, or excessive insertion loss during testing, simply submit end-face microscope photos or test spectra, and our senior engineers will conduct an online technical assessment within 24 hours. Once confirmed as a factory quality defect, we will immediately initiate expedited sample replacement and return/exchange procedures to resolutely protect your mass production schedule and procurement rights.
