Versatile Wavelength Range: Handheld Optical Power Meter supports 6 wavelengths (850nm, 1300nm, 1310nm, 1490nm, 1550nm, 1625nm) for comprehensive testing in communication engineering. This wide coverage reduces the need for multiple meters and enables testing across common fiber optic systems. Ergonomic Design: This Optical Power Meter features a universal interface compatible with FC, SC, and ST adapters, providing comfort and ease of use during long testing sessions. The universal interface minimizes adapter changes and helps maintain a stable grip during field work. MultiFunctional Capabilities: Handheld Power Meter offers relative power calculation, automatic range conversion, and battery power display for enhanced versatility and practicality. Users gain quick, reliable readings with less manual adjustment and can monitor remaining battery life at a glance. Quick and Accurate Measurements: The Optical Power Meter incorporates a sensitive chip for instant readings, allowing users to achieve accurate results without lengthy preheating times. This enables faster test cycles and more efficient workflow. Use scenarios Field installation and maintenance: During fiber network deployments or repairs, use the meter to verify signal levels across multiple standard wavelengths (850, 1300, 1310, 1490, 1550, 1625 nm). Confirm link integrity, detect drops, and validate power budgets without carrying multiple devices. RD and component testing: In the development or QA lab, quickly switch among the six wavelengths to characterize transceivers, optical switches, and passive components. Rely on immediate readings and auto range to streamline experimentation and data collection. Data center and campus fiber audits: For routine verification during rack mounting, patch panel testing, or troubleshooting, the meter provides dependable, on the spot measurements. Use relative power calculations and battery status to plan maintenance windows and ensure minimal downtime.
