The FTBx-730D is an advanced Optical Time Domain Reflectometer (OTDR) specifically engineered for PON (Passive Optical Network) FTTx and MDU testing. With the capability to perform in-service testing at 1650 nm and the option to integrate a GPON/XGS-PON power meter, this device stands out for its versatility and precision. It features impressively short dead zones — an event dead zone of just 0.5 meters and an attenuation dead zone of 2.2 meters, allowing for accurate measurements in challenging network environments. Supporting high port count PON splitters of up to 1×128, the FTBx-730D is optimized for future-ready network architectures. Designed for excellent durability, it includes a convenient swap-out connector that can be replaced to maintain peak performance over time without incurring significant service costs. Additionally, its iOLM readiness facilitates one-touch multiple acquisitions, presenting clear go/no-go results in an intuitive visual format. With a dynamic range of up to 42 dB, this OTDR can effectively handle distances of up to 132 kilometers for point-to-point applications, making it an essential tool for professionals in the fiber optics industry.
