Multi-Channel DFB High-Power Light Source Wavelength Can Be Customized

The four-channel DFB high-power light source is a high-performance fiber laser device that combines the excellent characteristics of DFB (Distributed feedback) lasers with a multi-channel design to provide stable, reliable and high-power laser output.

DFB lasers are famous for their high coherence, single frequency, single longitudinal mode output characteristics, and are widely used in optical fiber communication, sensing, measurement and other fields. The four-channel DFB high-power light source refers to the ability to output four different wavelengths of DFB laser at the same time, and each channel has a high output power.

Technical characteristics

High power output:
The light source can provide a high output power to meet a variety of applications requiring high power laser. The specific output power depends on the design and manufacturing level of the device, but usually a higher value can be achieved.

Multi-wavelength selection:
Four independent wavelength channels are available covering common communication and sensing wavelengths such as 850nm, 980nm, 1270nm to 1610nm (specific wavelength ranges may vary by product). Users can choose the appropriate wavelength combination according to the actual needs.

High stability:
High precision automatic power control (APC) and automatic temperature control (ATC) technologies ensure short - and long-term stability of light source output. This stability is essential for precision measurement and long-term monitoring.

Intelligent control:
