H720 High-end OTDR

Evaluating ultra-long-haul fiber spans requiring immense optical margin used to demand heavy bench-top equipment. Equipping our regional auditing teams with the H720-S5 (1310/1550nm, 45/43dB dynamic range) has transformed our field validation workflow. The instrument easily punches through high-loss spans over 120 km while maintaining low noise floors. Its onboard GPS and BeiDou positioning automatically geotag every trace, while IoT and Wi-Fi connectivity instantly upload test files directly to our central cloud platform and mobile Android App. This seamless cloud synchronization has cut our post-processing report turnaround time by over 60%.

In complex FTTx topologies with cascaded splitters, standard OTDR trace interpretation can be time-consuming for field crews. The H720’s Intelligent Optical Network Map (iONM) solves this by translating raw backscatter curves into clear, icon-based graphical link representations for rapid fault identification. The multi-tasking operating system allows technicians to run automated OTDR sweeps in the background while simultaneously performing fiber end-face connector inspections using the optional digital microscope probe or taking optical power measurements. It is a true flagship platform that bridges the gap between field operation and lab-grade diagnostics.

Procuring the H720-SM2 quad-wavelength model (850/1300/1310/1550nm) provided our enterprise teams with a single instrument capable of certifying both multimode datacenter backbones and single-mode metro links. Beyond its core OTDR performance, the integrated auxiliary toolset—including a built-in camera for documenting physical cabinet conditions, laser range measurement for site dimensioning, RJ45 cable tracking, and a visual fault locator—means our field technicians carry far less gear. The ruggedized chassis, dual Bluetooth/Wi-Fi remote assistant features, and long battery runtime make this the most complete all-in-one fiber test equipment available today.
