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.
