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:
Can be connected to the computer real-time display of output power,
wavelength and other key parameters.
Volume and weight:
It is usually a 1U/2U chassis, which is easy to place in the
laboratory or on the production line. Specific size and weight vary
from product to product, but generally moderate volume, easy to
handle and operate.
