The FTBx-730D is an advanced Optical Time-Domain Reflectometer (OTDR) specifically designed for in-service testing of Passive Optical Networks (PON) in FTTx and MDU applications. With the capability to test at 1650 nm and an impressive dynamic range of up to 42 dB, this tool effectively covers distances of up to 132 km in point-to-point configurations. Its short dead zones enhance the precision of testing, featuring an event dead zone of just 0.5 m and a PON dead zone of 30 m, ensuring accurate measurements even in complex network environments. This model also boasts a unique Swap-Out connector system, which allows for easy replacement to maintain peak performance without incurring excessive service costs. Designed to support high-port-count PON splitters (up to 1×128), it is ideal for demanding installations. Additionally, the FTBx-730D is iOLM-ready, enabling one-touch multiple acquisitions that yield clear, visual go/no-go results, streamlining the testing process for technicians. Compatibility with various EXFO products enhances its versatility, making it a valuable asset for professionals working in optical network management.
