Frequently Asked Questions (FAQ)

Q: What is the difference between Type 1 and Type 2 pinout configurations?

A: Type 1 follows the standard telecom butterfly pin configuration, commonly used for DWDM transmitters and high-speed optical communication applications. It provides dedicated connections for laser bias, RF modulation, TEC, thermistor, and monitor photodiode signals to ensure compatibility with telecom laser driver circuits.

Type 2 is optimized for pump laser applications, with a simplified electrical interface and a different TEC arrangement for high-power pump operation and thermal management.

Both configurations use the same 14-pin butterfly mechanical package, but their electrical pin assignments are different. They are mechanically compatible but require different PCB layouts and driver designs.

Q: Why is a built-in optical isolator important for DWDM and sensing applications?

A:In DWDM transmission and fiber sensing systems, optical reflections from connectors, fiber interfaces, and optical components may couple back into the laser cavity. This optical feedback can lead to mode instability, wavelength fluctuation, increased noise, and degraded system performance.

A built-in optical isolator with≥30 dB isolation suppresses these back-reflections, improving wavelength stability, reducing feedback-induced noise, and ensuring reliable operation in applications such as coherent detection, fiber sensing, and low-noise optical transmission.

Q: Can I get a custom wavelength outside the standard C+L band list?

A: Yes. We support customized wavelengths based on specific application requirements. For DWDM laser products, customized wavelengths are available within our qualified wavelength range (for example, 1527–1611 nm, depending on chip availability).

Other wavelength bands, including O-band (1260–1360 nm) and S-band (1460–1530 nm), can also be considered for specific applications.

Custom wavelength feasibility depends on laser chip availability, grating design, and production schedule. Please contact us with your target wavelength and application details for evaluation.
