FF-960 Mini OTDR

Conducting live network audits without severing active subscriber sessions requires specialized optical filtering. The FF-960 ultra mini OTDR excels in this role by utilizing a 1550 nm working wavelength integrated with a high-efficiency wavelength isolator and optical filter. It performs accurate trace checks on live fibers with active running signals regardless of whether the fiber remains connected to the OLT. The internal optics withstand up to 10 dBm of reflected input power, safely preventing optical receiver damage during live-line dispatches. Demonstrating a measurement range up to 80 km, this ultra-compact instrument gives our field crews true reflectometry diagnostics in a lightweight 0.5 kg body.

Deploying test tools across subcontracted field teams requires an instrument that is both user-friendly and electrically robust. The FF-960 features a 3.5-inch high-resolution touch-sensitive display with multi-point touch support, allowing technicians to navigate traces and menus smoothly. At a reference price of $169, it represents an incredible value for last-mile maintenance fleets. We also appreciate the hardware upgrade implemented by FirstFiber Technologies, which incorporates overvoltage protection into the power management circuit to prevent charging chip failures when field teams charge via USB cables or power plugs.
