Why you need this meter Fast, accurate optical power readings reduce troubleshooting time and help you make reliable decisions on-site. Broad wavelength coverage supports the common signals used in telecom, PON, and data networks so one tool handles most maintenance tasks. Long runtime and built-in calibration features keep the instrument ready for extended field work without frequent intervention. Key functions and benefits Accurate, fast measurements: built-in sensitive chip delivers precise results with quick response for efficient testing. Ten-wavelength support: measures 850, 980, 1270, 1300, 1310, 1490, 1550, 1577, 1625, and 1650 nm to cover standard communication and maintenance needs. Relative power calculation and calibration: enables comparative loss checks and on-site calibration for consistent, repeatable results. Low battery consumption: continuous operation up to 120 hours so you can rely on the meter during long shifts or multi-day jobs. Stable performance: designed to provide dependable readings across common operating conditions encountered in network maintenance. Compatibility and performance Function: optical power measurement, relative power calculation, and calibration support essential testing workflows. Compatibility: wavelength set covers most fiber communication systems including typical LAN/WAN, FTTH/PON, and test/commissioning scenarios. Performance: emphasis on measurement accuracy, fast response time, and extended battery life to minimize downtime. Typical use scenarios Installation and acceptance testing: verify transmitter power and link loss across the wavelengths used by the network before handover. Routine maintenance and troubleshooting: quickly locate power drops or verify signal levels on live fiber runs in data centers or telecom closets. PON and service verification: check downstream/upstream wavelengths (including 1490 nm and 1550 nm) and validate optical power during commissioning and upgrades. Practical notes Use the relative power and calibration functions for baseline comparisons and to confirm connector or splice performance. The meter’s 10-wavelength range means fewer instrument changes when testing mixed systems or multi-service fibers. Expected continuous operating time is approximately 120 hours under normal battery conditions; plan charging intervals accordingly. Multifunctional optical power meter — accurate, fast, and engineered to handle the wavelength and runtime demands common to communication maintenance tasks.
