C/L/CL/O Band Adjustable Light Source Module Built-In Chassis
U8712M Tunable Laser Mini Module offer superior performance
for the testing of DWDM components, AWG & PLC components,
optical amplifiers, and other general purpose fiber optic test and
measurement applications. It’s specifically designed for fast sweep
fiber grating sensor testing.
U8712M Mini module can be connected to a PC with a USB
cable. They are highly accurate, powerful, compact-sized,
fast-starting, and affordable tunable laser source systems which
provide C band 1 or 2 Laser output options. Module control software
is also included on purchase. The module can also be integrated
into any requested prodUts system with RS232 interface controls and
an output triggered BNC port.
Principle of adjustable light source:
Mainly through the control of current and voltage, frequency size
of the output to achieve LED dimming function. Specifically, the
adjustable light source works by adding a wavelength selection
optical device (frequency selector) to the laser cavity, so that
only the selected wavelength can form resonance and emit laser
light. The selection of wavelength can be achieved by adjusting the
parameters of the frequency selector, such as adjusting the length
of the FP-cavity, the Angle of the grating, etc. According to the
design principle of the frequency selector, the wavelength of some
tunable lasers can be continuously scanned (also known as scanning
laser), and some can only set the wavelength at a single point,
known as the cutting wave light source.
