This visual fault locator series combines trusted fiber-optic principles with practical modern functionality. The 650 nm red laser provides clear and intuitive fault tracing in both single-mode and multi-mode fibers, while selectable continuous-wave and pulsed modes offer flexibility for field technicians. Its rugged, waterproof construction is built to withstand demanding environments, and the integrated LED lighting supports work in dark or confined spaces. A high-capacity rechargeable lithium battery ensures extended operating time, and the universal 2.5 mm interface makes the tool compatible with both UPC and APC connectors. This is a dependable, technician-focused instrument designed for everyday fiber installation, troubleshooting, and quality assurance.
