Fast Tunable Laser Source Module

Product Details


The GM82020 fast tunable laser source module is mainly used for the measurement and application of high-precision wavelength division multiplexing DWDM components, optical waveguide grating array AWG components, planar optical waveguide PLC components, optical amplifiers EDFA and other general fiber optics, and is especially suitable for the fast scanning test of fiber grating sensors. The GM82020 series of modules offer superior performance with a wavelength scanning speed of 30 nm/s (10pm step).


The GM82020 fast tunable laser module can be connected to a computer via a USB cable and communicates with the PC control software provided by UC Instruments to form a tunable laser source measurement system with high precision, high power, compact size, fast startup and low price. Our company can provide C-band and L-band GM82020 tunable laser light source modules for users to choose. At the same time, this series of modules can be specially customized and controlled through RS232 interface.

The BNC output trigger port is integrated into the customer's production system.
