Optical Power Measurement-Can measure single-mode wavelengths like 1310, 1490, 1550, and 1625nm with measurement range from -60 to +8dBm. Fiber Interfaces-The optical power meter supports FC, ST, and SC universal interfaces. With a strong light source, it is easy to penetrate long-distance optical fiber. RJ45 Network Test-Automatically scan, and detect the order of the network cable. Visual Fault Locator - Where a fiber optic cable has a break or bending, connect it to NF-908L or 908S. Locate the breakpoint with the visible red light. LAN Cable Finder-The NF-908S upgrade digital signal scanner, can assist you in finding the correct LAN cable in a mess of cables Portable Equipment-The one-piece detachable design can be used flexibly and is easy to operate with one hand.
