Description

The FTBx-735D is the OTDR of choice for field technicians who need a high-resolution tool for metro network testing and splitter characterization in PON FTTx/MDU applications. It is optimized for the rollout and troubleshooting of metro/core and FTTx networks.

The FTBx-735D OTDR is designed to support high port-count splitters (up to 1x128) and point-to-point (P2P) testing up to 144 km, thanks to its dynamic range of up to 45 dB. Its advanced features, including live fiber testing and short dead zones, make it ideal for precise fault location.

The FTBx-735D advantage

Accurately characterize high port-count PON splitters and metro links with dynamic range up to 45 dB for up to 144 km point-to-point (P2P).
Identify faults closer to splitters with short event and attenuation dead zones.
Simplify in-service troubleshooting with a single port, optional in-line 1490/1550 nm PON power meter, and user-friendly graphical interface.
