Frequently Asked Questions

What is a DFB pigtailed laser diode?

A DFB (Distributed Feedback) pigtailed laser diode uses a diffraction grating within the semiconductor structure to achieve single longitudinal mode operation, making it ideal for high-speed, long-distance optical communication.

Do you offer custom wavelengths?

Yes, we provide OEM/ODM services and can customize laser diodes for specific wavelengths within the 1310nm to 1650nm range.

What is the difference between PIN and APD photodiodes?

PIN photodiodes are used for medium-light detection with no internal gain. APDs (Avalanche Photodiodes) provide internal gain through avalanche multiplication, making them suitable for low-light, long-haul applications.

Are your products compliant with international standards?

Yes, we strictly adhere to ISO9001 quality management standards, ensuring consistent quality and reliability across all our products.
