Usb Optical Power Meter Power Probe Multi Meter Small And Convenient
overview
The sampling period of U8721 high-speed optical power meter module of Guangzhou Youxi can reach uS level, which can collect and process data more quickly. The power meter module uses USB communication interface, can communicate with PC directly, through the configuration software to display data and set parameters.
The U8721 high speed optical power meter module can be used in high precision wavelength division multiplexing DWDM element, optical waveguide grating array AWG element, planar optical waveguide PLC element, WSS, OPM, DPSK, optical amplifier EDFA and other general optical fiber measurement applications. And the U8721 model has the A/B/C/D/H, and different models have different functions.
Laser signal input port. When connecting the fiber jumper to the optical power meter module, you need to use a connection adapter in the middle. The connection adapter must match the type of both the power meter interface connector and the optical fiber connector.Two typical connection adapters are listed for connecting optical fibers to the U8721 optical power meter.
