Product description

The All-in-One Fiber Optic Identifier with Optical Power Meter and Red Light Source is an essential tool for fiber optic maintenance. It enables non-destructive fiber identification, precisely measures optical power loss(via built-in power meter), and verifies fiber continuity(using a 650nm red light source). Compatible with both single-mode and multi-mode fibers, it allows live fiber testing without service interruption by detecting modulated signals(1310/1550nm wavelengths with 270Hz/1KHz/2KHz tones)injected at the fiber end. This ensures accurate tracing and isolation of target fibers during installation, maintenance, or troubleshooting in complex optical networks.
