The Exfo AXS-100 is a handheld optical time-domain reflectometer designed for singlemode fiber testing and troubleshooting in access networks, FTTx, and PON architectures. Its dedicated 1625 nm port with wavelength filtering enables in-service testing without disrupting active network traffic. The instrument delivers intuitive one-button operation through proprietary FTTx software, producing immediate pass/fail results, macrobend detection, and fault location.
