1: What tests are conducted before product shipment?
A: Before shipment, tests are conducted to confirm transmission/reflection insertion loss, isolation, ripple, PDL, return loss, directivity, center wavelength, end-face quality, appearance, and packaging reliability. This product is designed to address power budget and crosstalk issues in FTTH network upgrades and is suitable for access network projects with high requirements for low loss, high isolation, and batch consistency.
2: What are the warranty policy and after-sales support?
A: This product is ISO9001 and RoHS certified. If non-human-caused quality problems occur within the warranty period, we can provide parameter retesting, root cause analysis, repair, or replacement support. It is recommended to confirm complete specifications before placing an order, including transmission band, 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.
