1: What tests are conducted before product shipment?
A: Before shipment, tests are conducted to confirm the center wavelength, passband/reflection band insertion loss, isolation, ripple, PDL, return loss, directivity, endface quality, appearance, and packaging reliability. This product is based on TFF thin-film filtering technology and an all-fiber structure, suitable for FTTx and DWDM projects with high requirements for stability, low loss, and batch consistency.
2: What are the warranty policy and after-sales support?
A: This product is ISO9001 and RoHS certified. If the product has non-human-caused quality problems within the warranty period, we can provide parameter retesting, root cause analysis, repair, or replacement support. It is recommended to confirm the complete specifications before placing an order, including wavelength combination, passband/reflection band, fiber type, connector, package size, optical power, and application environment; the specific warranty period, RMA process, and scope of responsibility are subject to the formal quotation or purchase contract.
