PON Single-Mode 1625nm OTDR with VFL & Optical Power Meter
The D-TECH PON Single-Mode 1625nm OTDR is a compact, cost-effective optical fiber testing instrument specifically designed for FTTH, GPON, EPON, and PON network maintenance. Operating at a dedicated 1625nm wavelength, it performs accurate online fiber testing without interrupting live network traffic, making it ideal for troubleshooting active optical networks.
The unit integrates an Optical Time Domain Reflectometer (OTDR), Visual Fault Locator (VFL), and Optical Power Meter (OPM) into one portable device. It quickly detects fiber breaks, bends, splice loss, connector reflections, and attenuation events while providing simple operation, lightweight portability, and long battery life for field engineers.

Applications
FTTH & GPON Networks
Designed for installation, maintenance, and troubleshooting of FTTH and PON optical networks.
Live Fiber Testing
Performs online testing at 1625nm without interrupting active communication services.
Fiber Maintenance
Quickly locates fiber breaks, macro bends, connector faults, and splice loss.
ISP & Telecom
Suitable for broadband providers, telecom operators, CATV systems, and enterprise fiber networks.
Testing Recommendation
Use the dedicated 1625nm wavelength for online testing of live PON networks without interrupting service. Clean all optical connectors before testing to ensure accurate OTDR traces and power measurements. Utilize the integrated VFL for quick visual fault identification and the built-in Optical Power Meter to verify signal levels before and after maintenance activities.
