Optlise Kiu Määraja ST820B

ST820B Optical fiber identifier is an essential installation and maintenance instrument by inserting fiber into its adapter head, it can identify SM optical fibers without any damage by detecting the optical signals being transmitted through them so that avoid to opening the fiber at the splice point for identification and interrupting the service.
