FAQ
1: Can I purchase samples for verification first? What is the MOQ?
A: Yes. The product page shows an MOQ of 1 piece, suitable for engineers to conduct sample testing, link verification, polarization axis confirmation, and system compatibility assessment. After sample confirmation, small-batch trial production or mass production can proceed according to project requirements.
2: How are lead times and discounts confirmed for bulk orders?
A: Bulk lead times depend on the number of channels, wavelength scheme, packaging structure, connectors, fiber length, and testing requirements. The page shows a monthly supply capacity of 100,000 pieces; for bulk orders, annual projects, or long-term supply needs, we can provide tiered pricing and project lead time assessments based on quantity, delivery batches, and customization complexity.
