QIIRUN OTDR Fiber Optic Tester SM 1310/1550nm 32/30dB, Optical Time Domain Reflectometer with 0.8m Dead Zone 160km Range, 7-inch Touchscreen, OPM VFL OLS Event Map, Multifunctional Test Kit

Brand: QIIRUN

Color: Blue

Features:

• 32dB High Dynamic Range & 0.8m Dead Zone – With 32dB/30dB dynamic range at 1310/1550nm, this professional-grade single mode OTDR detects signals along fiber runs up to 160km with 128,000 sampling points for high-resolution fault location. The 0.8m event dead zone (half the 1.5m of standard OTDRs) means you can detect splices and connectors very close to the launch point—critical for high-density data center cabling, GPON/EPON access networks, and carrier-grade backbone fiber.
• Multifunctional All-in-One Fiber Test Platform – Integrates OTDR + Optical Power Meter (OPM, -70~+10dBm, 6 calibration wavelengths) + Visual Fault Locator (VFL, 10km / 650nm) + Optical Light Source (OLS, 1310/1550nm) + Event Map in a single handheld unit. Eliminate the need to carry multiple instruments for construction, commissioning, and maintenance workflows. FC / SC / ST / LC adapters included for universal connector compatibility.
• 7-inch Capacitive Touchscreen & One-Touch Auto Testing – The large 7-inch touch display gives engineers a clear full-resolution view of OTDR traces—ideal for field analysis without squinting at a 4-inch screen. Event Map delivers automatic one-key testing with Pass/Fail judgment, dual-wavelength 1310nm & 1550nm simultaneous measurement, and multi-curve comparison for splice loss and ORL analysis. SOR-format files are PC-compatible for offline analysis, report generation, and printing.
• 160km Long-Range Test with 128,000 Sampling Points – Supports test ranges from 500m to 160km with 14 pulse widths (3ns to 20μs), suitable for short-haul FTTH/FTTX cables as well as long-haul trunk fiber. With 128,000 sampling points and 0.001dB loss resolution, every splice, bend, and connector shows up on the trace. Built-in 8G storage saves up to 80,000 curves. Operates at -10°C to +50°C—fully field-ready in both winter construction and summer outdoor environments.
• 8–10 Hour Field Battery & Professional-Grade Build – The large 7.4V / 6.6Ah lithium battery delivers 8–10 hours of continuous operation, covering a full day of site work on a single charge. The rugged 230×185×70mm housing weighs just 1.5kg for easy carry. Package includes: OTDR unit, SC/FC/ST/LC adapters, USB data cable, AC charger, 8G storage, carry case, user manual, and calibration certificate. Ideal for fiber ISPs, telecom contractors, enterprise network teams, and cable plant engineers.
