The Remote Fiber Test System (RFTS) comprises the RTU-4000 platform with the RTU-4100 OTDR optical test module. The RFTS monitors optical fiber infrastructures in Core, Metro, Access and FTTx/PON networks, improving workflow and reducing Mean Time to Repair (MTTR). Centrally and remotely managed OTDR unit for auditing, troubleshooting and monitoring FTTx fibers. Smaller, denser and scalable: combine modular and external switch (local or remote) to OTDR and scale up to 1024 ports per test head within 3U rack height Scalable EMS supporting over 1,000 remote. The AQ7277B delivers precise, high-resolution reflection analysis for fiber-optic network monitoring and troubleshooting. Designed for demanding applications in telecommunications operations, maintenance, and aerospace remote sensing, this remote OTDR enables Remote Fiber Test Systems (RFTS). Automate optical network monitoring with the modular rack-mounted, automated OTDR test unit that offers a wide range of OTDR modules to make traditional OTDR traces as well as DTS and DTSS (Distributed Temperature and Strain) measurements. RFTS can operate as standalone device or as part of a centralized monitoring system. Remotely managed OTDR instrument provides capability to continuously monitor. Visualize network issues and discover improvements with the ONMSi RFTS portfolio that scales from one fiber to cover the entire fiber network! The award-winning ONMSi Remote Fiber Test and Monitoring platform helps transform fiber network performance by making all issues visible: The flexible ONMSi. EXFO's remote fiber testing and monitoring (RFTM) solution provides increased visibility over critical fiber routes by connecting them to fixed and centralized OTDR-based test equipment—from the initial deployment phase to maintenance and field repairs.
