NOYAFA NF-981 OTDR Fiber Optic Tester, Multi-Function Optical Time Domain Reflectometer

The NOYAFA NF-981 OTDR Fiber Optic Tester is a professional multi-function fiber testing tool designed for accurate and efficient optical fiber network analysis. Equipped with OTDR, Optical Power Meter (OPM), Visual Fault Locator (VFL), Wire Mapping, and Length Measurement functions, it is ideal for network engineers and technicians handling fiber optic troubleshooting and maintenance.

Key Features:

• 🔹OTDR Function – Supports single-mode fiber testing at 1310nm/1550nm with a dynamic range of 24dB/22dB, covering test distances from 10m to 60km.
• 🔹Intelligent Optical Link Analysis – Generates detailed test reports on reflective events, fiber end, and faults.
• 🔹Optical Power Meter (OPM) – Measures optical power from -50dBm to +26dBm with six wavelength calibration (850/1300/1310/1490/1550/1577/1625nm).
• 🔹Visual Fault Locator (VFL) – Built-in 10mW red light source for quick and precise fault detection.
• 🔹Wire Mapping & Length Test – Detects short circuits, open circuits, and crossed wires in LAN cables and measures cable lengths up to 600m.
• 🔹Rechargeable Battery – 4000mAh lithium battery supports over 11 hours of standby and 6 hours of continuous testing, with Micro USB 5V/2A charging.
• 🔹LED Lamp – Built-in illumination for dim working environments.

Important Notes:

• 1️⃣This OTDR cannot test live fibers; doing so may damage the instrument.
• 2️⃣ Not suitable for splitter testing (requires a 42dB+ dynamic range).
• 3️⃣ For accurate test results, always clean fiber connectors with alcohol cotton before testing.
• 4️⃣ The NOYAFA NF-981 OTDR Fiber Tester is factory-tested to ensure quality and reliability. Please ensure you have professional experience before purchasing.

• Fiber Optic Tester: The 8-in-1 fiber optic tester is built in OTDR, OPM, Visual Fault Locator, Optical Light Source, Event Map (IOLM), RJ45 Sequence Test, Loss Tester and Smart Systerm Set. It is can quickly and accurately detect the location and type of fiber optic cable fault points.

• OTDR Tester: Note: don't use this function with lamp. Test Wavelength 1310/1550nm,Test Range 10m~60km. Dynamic Range 24dB/22dB (Note: Can't test spliter) Connector FC/APC (Interchangeable SC、ST) or connector FC/PC (Interchangeable SC、ST). This OTDR supports real time measuring function,can store it as SOR format file. Report include event information, link length, link loss, average loss. This OTDR meets the growing demands of modern fiber optic systems

• Optical Power Meter: FC/APC (Interchangeable SC、ST) or FC/PC (Interchangeable SC、ST) and other interfaces are universal. Support the test of different wavelengths of the red light source (650nm±20nm) and optical power/light source (850nm, 1300nm,1310nm, 1490nm, 1550nm, 1625nm); Optical fiber fault detection, optical fiber breakpoint location, optical transmitter power measurement (dBm and W), optical fiber line loss test

• Event Map & Light Source: The event map function is one-click automatic test, which displays the length of the optical fiber link under test, event point type, breakpoint location and other information in a graphical form. The stable light source is used for telecommunications, CATV, and LAN optical cable parameter testing.

• Cable Length Test: The RJ45 cable tester can quickly measure the length of the cable with a range of 200m. Please connect the remote module for RJ45 line sequence measurement during the test.
