    Publish time 2021-05-24 10:11    

 Product overview

  JW3220 is a new version 3.5-inch color screen version of high-precision optical power meter that developed by Shanghai Joinwit. In addition to providing superior dynamic range and linearity technical index, it is also equipped with rich menu function design, it covers the functions of threshold alarm configuration, real-time monitoring of maximum and minimum power change, frequency signal detection and visual fault locator. When used in conjunction with our light source, it has the function of automatically identifying the wavelength of the light source, which is very convenient for testing the link loss, and can store and upload the test data of the instrument. The instrument provides the standard communication interface protocol, which is convenient for the user to embed the system or secondary design and development. It is an ideal tool for the maintenance and communication teaching and research of optical fiber engineering.
