The Mini OTDR with OPM, OLS, VFL & Ethernet Tester – FT-4200S is a versatile, user-friendly compact tool perfect for anyone working with fiber optic networks. Easy to transport and keep in your toolkit as its small enough to fit into a large pocket. Whether you’re a professional network engineer, a fiber installer, or simply a tech enthusiast, this all-in-one device makes fiber testing simple and efficient.

The FT-4200S combines multiple essential functions into one compact unit. It acts as an Optical Time Domain Reflectometer (OTDR) for identifying faults and measuring fiber lengths, an Event Map feature (similar to IOLM from Exfo), an Optical Power Meter (OPM) for checking signal strength, an Optical Light Source (OLS) for fiber testing, and a Visual Fault Locator (VFL) for pinpointing breaks and bends. Additionally, it includes an Ethernet tester, making it a comprehensive tool for both fiber optic and network testing.

Designed with a rugged exterior for durability, the FT-4200S is built to withstand the demands of fieldwork. Its intuitive interface ensures that even those new to fiber optic testing can operate it with ease, while its advanced features cater to the needs of experienced professionals. With the FT-4200S, you get precise measurements, fast diagnostics, and reliable results, all in a portable, easy-to-use package. Whether you’re maintaining a home network or managing large-scale fiber installations, this tool is a must-have for ensuring your connections are always at their best. You are additionally able to export your OTDR or event map results and from your PC you can print the .SOR file to a .PDF if needed. The FT-4200S includes an 8GB memory card that also has the software for your PC installed on it so you can export files when needed.

*Its important to note that this OTDR is not designed to operate with splitters.
