GRANDWAY FHO1500 OTDR for FTTH Last-Mile Testing
Initially, the GRANDWAY FHO1500 Last Mile Explorer is a professional OTDR for testing the last section of a fiber optic network. The technician uses the short dead zone to examine nearby events, connectors, and loss points with greater accuracy. This allows them to identify problems faster in FTTH installations and networks.
In addition, the FHO1500 offers an event dead zone of ≤1 m and an attenuation dead zone of ≤4 m. At the same time, the instrument has a dynamic range of 20 dB and operates at 1625 nm or 1650 nm. Therefore, the technician can analyze the last mile of the optical connection in greater detail.
However, a simple optical power measurement does not always show the exact point of a fault. For this reason, the OTDR analyzes the fiber path and helps the technician determine the distance of a problematic event. In this way, it reduces diagnosis time and helps organize connection restoration more effectively.
Last-Mile OTDR for Fault Detection
In addition, the GRANDWAY FHO1500 combines OTDR, VFL, Optical Power Meter, and stable light source functions. This allows the technician to perform different tests with one portable device.
At the same time, the Bluetooth connection allows the technician to transfer measurement files to their mobile phone. In addition, they can view the OTDR trace from a compatible mobile device. Therefore, they can manage results more easily during field work.
Then, to better understand events, losses, and reflections, read the guide
how to read an OTDR trace, events, losses, and reflectance.
This allows you to correctly interpret the information displayed by the measurement trace.
