Optical Power Meter & Fiber Identifier for PON Network Testing — 1310nm/1490nm/1550nm, 0.1 DB Resolution

One Step Electric Fiber Optic Identifier Live with 0.1 DB resolution — a user-friendly tool engineered to speed up fiber testing and fault finding. This instrument reliably detects live optical signals in both single-mode (SM) and multimode (MM) fibers, making it suitable for telecom, data center and general networking work. The unit supports key PON test wavelengths (1310nm / 1490nm / 1550nm) while also covering a broad operational band from 850–1700nm for compatibility with a wide range of fiber types. Built-in Visual Fault Locator functionality provides clear visual indication of breaks or defects to simplify troubleshooting and reduce repair time. Compact and efficient, this detector delivers quick, accurate identification of fiber signals and faults to streamline installation, maintenance and verification tasks.
