PON Single-Mode 1625nm OTDR with VFL & OPM
The D-TECH PON Single-Mode 1625nm OTDR is a cost-effective and user-friendly testing device designed specifically for FTTH network environments. It focuses on a single 1625nm wavelength, allowing efficient and accurate fiber testing while reducing the complexity and cost associated with multi-wavelength OTDR systems.
This OTDR enables non-intrusive online testing without interrupting live optical signals, making it ideal for maintenance and troubleshooting in active fiber networks. With built-in VFL and Optical Power Meter (OPM), it provides a complete solution for fiber inspection, fault location, and signal verification.
