Overview
The VT-42PPM-3 is a specialized optical power meter for GPON, EPON, and GEPON networks, allowing simultaneous measurement of three wavelengths—1310 nm, 1490 nm, and 1550 nm—without service interruption. The device helps technicians quickly assess signal quality on PON networks, supporting on-site testing, maintenance, and troubleshooting.
Feature
- Simultaneous measurement of three PON wavelengths: 1310 nm, 1490 nm, and 1550 nm.
- Supports measurement on GPON, EPON, and GEPON networks.
- Simultaneous display of power for all three wavelengths on a single screen.
- Color LCD screen, clear and easy to read.
- PASS/WARNING/FAIL threshold evaluation function.
- Supports customizable threshold settings.
- Memory stores up to 900 measurement results.
- Connects to a computer via USB port for data management and export.
- Compact and lightweight design, convenient for field use.
- Suitable for installation, acceptance testing, maintenance, and troubleshooting of FTTH/PON networks.
