Detailed Product Description * Live fiber identification. * Core power measurement * 270 Hz, 1000 Hz, and 2000 Hz * optical fiber identifier 800-1700nm Optical Fiber Identifier The 3C-OFI-001 optical Fiber Identifier are rugged, handheld, easy-to-use installation and maintenance instruments that identify optical fibers by detecting the optical signals being transmitted through a singlemode fiber. By utilizing local detection technology (non-destructive macro-bend detection), they eliminate the need to open the fiber at the splice point for identification. This, in turn, eliminates the probability of interrupting service . Highlights @Operates from 800-1700 nm. @Compatible with most AT&T and Corning optical fiber. @Uses non-destructive, macro-bending technology. @Detection sensitivity of -40 dBm. @Bi-directional traffic indication. Applications @Live fiber identification. @Core power measurement and display on a 2-digit LED display . @270 Hz, 1000 Hz, and 2000 Hz modulated tones detection. @Relative zero power reading . @Power loss through a splice or a connector measurement .
