The FTBx-730D from EXFO America is a sophisticated OTDR designed specifically for PON FTTx and MDU applications, offering exceptional testing capabilities at a wavelength of 1650 nm. With support for high port count PON splitters of up to 1×128, this device is ideal for extensive fiber networks, ensuring reliability even in complex setups. Its impressive short dead zones—event dead zone of just 0.5 m and attenuation dead zone of 2.2 m—allow for precise measurements without interference from neighboring signals, while the PON dead zone of 30 m minimizes blind spots in testing. Engineered for optimal functionality, the FTBx-730D features a replaceable Swap-Out connector, which allows for continuous performance over time without incurring excessive service costs. Adding to its versatility, it is equipped with iOLM functionality for one-touch multiple acquisitions, resulting in clear and straightforward go/no-go results that streamline the testing process. With a dynamic range of up to 42 dB, this OTDR is capable of supporting extensive point-to-point connections up to 132 km, making it a vital tool for any professional in the fiber optic field.
