• "2-in-1 Multifunctional Design": This fiber optic tester integrates an Optical Power Meter (OPM) and a Visual Fault Locator (VFL) in one device, eliminating the need for separate tools. It supports 10 optional wavelengths (850nm/980nm/1270nm/1300nm/1310nm/1490nm/1550nm/1577nm/1625nm/1650nm) with a measurement range of -50~+26dBm and ±0.2dB accuracy, ideal for professional fiber network testing.
• "Universal Interface Compatibility": Equipped with a universal FC/SC/ST interface, this OPM+VFL tester works seamlessly with most standard fiber optic connectors. For 1.25mm LC interface testing, simply use an optional FC-LC adapter (sold separately), making it suitable for various fiber cable installation and maintenance scenarios.
• "High Precision & Reliable Performance": Featuring self-calibration function and stable LED red light source, this optical power meter delivers precise, consistent measurements. The shockproof and durable ABS housing ensures long-term use in harsh field environments, with backlight support for clear reading in low-light conditions.
• "User-Friendly Operation & Large Data Storage": The intuitive 6-button control panel and large LCD backlight display make operation simple for both beginners and technicians. It can store up to 1000 sets of test data for easy viewing and analysis, with an auto 10-minute shutdown function to save battery life.
• "Portable & Long-Lasting Power Supply": Powered by 2x AAA (No.7) dry batteries(Battery not Included), this fiber tester offers ultra-long battery life for all-day field work. Its compact, ergonomic design is easy to carry in a tool bag, perfect for FTTH construction, fiber optic cable troubleshooting, and telecom network maintenance.
