The Optical Time Domain Reflectometer (OTDR) is a multifunctional optical measurement instrument designed for fiber optic construction, maintenance, and troubleshooting. It integrates multiple essential tools — OTDR, event map, optical power meter (OPM), visual fault locator (VFL), light source (LS), optical loss tester, and RJ45 cable tracker — into one compact, easy-to-use device.
With its high-performance CPU, 4.3-inch touch screen, and dual-wavelength support, this OTDR delivers fast, accurate, and reliable test results for fiber network professionals.

All-in-One Functionality: OTDR, OPM, VFL, LS, optical loss test, RJ45 cable tracker & sequence test.
High Precision: Small event blind zone (1.5m) and excellent short-fiber performance.
Fast & Smooth Operation: Powered by a high-speed processor for responsive performance.
Dual-Wavelength Support: 1310/1550nm or optional 1625/1650nm for advanced fiber analysis.
Full-Screen Curve Display: 4.3” color TFT LCD (800×480) with multi-touch interface.
Large Storage Capacity: 8GB memory for over 20,000 SOR-format test curves.
Lightweight & Portable: Compact design (≤0.5kg), perfect for field engineers.
Wide Application: Ideal for FTTH, telecom, LAN/WAN installation, and optical cable testing.
