Frequently Asked Questions

What is a fiber array?

A fiber array is a precision assembly that aligns multiple optical fibers in a fixed configuration, typically using a V-groove substrate, for efficient coupling to photonic devices.

Can you customize fiber arrays?

Yes. MEISU specializes in custom fiber arrays with varying fiber counts, angles (e.g., 45°, 90°), coatings, and packaging to meet specific application needs.

Do you support high-temperature applications?

Yes. We offer HT fiber arrays rated up to 260°C and collimators up to 1000°C for extreme environments.

What is the lead time for custom designs?

Prototypes typically take 4–6 weeks. Mass production timelines depend on complexity and volume. Contact us for details.
