The Mini OTDR DE1201 is a compact, multifunctional Optical Time Domain Reflectometer designed for fast, precise testing and troubleshooting of single-mode G.652 fibre networks. With support for 1310nm and 1550nm wavelengths, this mini OTDR delivers a dynamic range of up to 26dB, ideal for FTTx, CATV, PON, and access network maintenance.

Equipped with a 4.3” multi-touch TFT display, the DE1201 features advanced testing modes including event and attenuation dead zone detection, real-time refresh, and multi-wavelength power measurement (OPM) with optional laser source output. It supports up to 128k sampling points, 0.001m resolution, and SOR file format exports for detailed fibre event mapping.

Additional features include:

• Event dead zone: ≤2.5m

• Attenuation dead zone: ≤8m

• Range: up to 100km

• Laser safety: Class 2

• Universal FC/SC/ST connectors

• Auto/manual testing modes

• Built-in OPM & stable light source

• Cable hunt & length detection (≤300m)

• 8GB internal storage with USB Type-C

With long battery life (12h+ test time), robust data handling, and ultra-light portability (≤0.5kg), the Attac DE1201 Mini OTDR is an essential field tool for fibre installers, network engineers, and telecom technicians.
