DCONNECT TC-300 OTDR Fiber Tester

The DCONNECT TC-300 combines OTDR testing, optical power measurement, visual fault location, and optical light source functions in one professional fiber optic tester. It supports 1310nm, 1550nm, 1625nm, and 1650nm single-mode wavelengths and 850nm and 1300nm multimode testing, with dynamic range up to 42dB. The single-mode testing distance can reach up to 240km, while multimode testing supports distances up to 80km. Advanced measurement performance includes 0.05m minimum sampling resolution, 256,000 sampling points, ≤0.05dB/dB linearity, 0.001dB loss resolution, and 0.01m distance resolution. The integrated OPM supports Type A -10dBm to -70dBm and Type B +23dBm to -50dBm, while the 10mW CW VFL and optical laser source support additional fiber testing functions. The 5.6-inch TFT-LCD touchscreen, event map, 8GB internal memory, 32GB SD card support, dual batteries, and optional 400× fiber inspection make the TC-300 suitable for professional fiber optic network testing and maintenance.
