PON Optical Power Meter This PON optical power meter is an essential tool for the installation, operation, and maintenance of fiber optic networks. It features a color LCD screen capable of measuring and displaying voice, data, and video signals simultaneously on the PON architecture. It also tests the 1310nm uplink and 1490nm & 1550nm downlink signals in the PON system. The device supports ten data storage entries. Save the current power value with a long press on V/LOAD, or view saved values with a short press on the same button. Features: Ideal for fiber optic network installation, operation, and maintenance. LCD screen displays simultaneous measurements for voice, data, and video signals on the PON architecture. Tests 1310nm uplink and 1490nm & 1550nm downlink signals simultaneously. Removal port for weak light remediation; release port checks optical modem connectivity. USB port supports charging; rear bracket aids desktop placement. Ten data storage capacity, with easy save and view functionality via V/LOAD button. Self-calibrate with a manual mode by pressing EEF+SEL simultaneously. Timer shutdown function: hold the power button for 2s during startup to activate, with indicators for automatic shutdown.
