FTTH S310N Active Fiber Mini Tester — Multifunction Optical Power Meter, Stable Light Source & OTDR (Accurate Identification)

Compact multifunction tester FTTH S310N combines an optical power meter, visible and stable light sources, and an OTDR into one portable unit for fiber maintenance and identification. Power and environment: operates in a power supply mode with lithium electricity and a 4000MAH battery for extended field work; rated operating temperature range is -10 to +50 degrees. Optical power meter: includes a Standard Light Power Meter covering 800-1600nm. The probe-type meter measures power from -70 to +5dBm (broadcasting range -50 to +25dBm) with 5% measurement accuracy and a display resolution of 0.1dBm. It is designed for single-mode optical fiber interfaces such as SC. Visible red light source: provides a 650nm red output using an FP-LD emitting device at 5mW, with selectable modulation of 0HZ, 1HZ, and 2HZ; suitable for single-mode optical fiber interfaces like SC. Stable light source: offers wavelengths of 1550nm and 1610nm via an FP-LD emitter, outputting -10dBm and supporting modulation options 270HZ, 1K, and 2K; compatible with single-mode optical fiber interfaces. OTDR functionality: built-in OTDR operates at 1550nm and 1610nm with an avalanche APD detector diode. It delivers a satellite resolution of 0.6 meters, can locate events up to 50km, test attenuation up to 30km, and has a blind area of 10 meters. Multiple pulse width options are available and the device provides a scatterion depth of 20dB for thorough link diagnostics.
