OFI-201 Optical Fiber Identifier is an essential installation and maintenance instrument. By inserting the fiber into its adapter to avoid the opening of the fiber at the splice point for identification and thus avoids the interruptiion of the service. In the presence of traffic, the intermittently audible tone is activated. This optical fiber identifier also allows relative core power display and identification of the 270 Hz, 1k Hz, and 2k Hz frequencies. When they are used to detect the frequency, the continuously audible tone is activated. There are four adapter heads available: Φ0.25, Φ0.9, Φ2.0, Φ3.0. This optical fiber is powered by a 9V alkaline battery.
