YW-571 is an instrument used to test continuous optical signal power, optical fiber link loss and optical fiber line on and off. It can be used for optical cable construction and maintenance, optical fiber communication, optical fiber sensing and optical fiber CATV, etc..

 

YW-571 can test 8 kinds of wavelengths, and supports simultaneous display of linear and non-linear indicators, which can meet the testing needs of users in different occasions. The instrument also has a 650nm wavelength laser, which supports constant red light and flashing, which can be used to quickly detect fiber connectivity and fiber failure points.

 

YW-571 has wavelength memory function. When the instrument is turned on, it will automatically display the wavelength that was set when it was turned off last time. This function can reduce the operation of repeatedly setting the wavelength to a certain extent, and provide users with convenience, especially when it is often necessary to test a specific wavelength. In addition to testing optical power, YW-571 can also be used to calibrate network cables. As long as the cables are inserted into the RJ45 ports of the host and accessories, you can judge whether the cable has short circuit, open circuit, or disorder according to the LED indicator. YW-571 is small, easy to carry.
