1. The integrated optical power meter, red light source, and LED flashlight (only the MT-7618 model is equipped with the red light source) can complete fiber power detection, breakpoint location, and on-site lighting, meeting various fiber construction requirements.
2. 8-wavelength measurement, wide compatibility: supports 8 commonly used fiber wavelengths (850/980/1300/1310/1490/1550/1625/1650nm)
3. Equipped with a 2.5mm universal interface, compatible with ST/SC/FC connectors, suitable for most fiber link testing scenarios
4. Large-capacity data storage, with wavelength memory: can store 500 sets of measurement data, supports circular coverage, and can be browsed and viewed; the wavelength memory function automatically restores the last shutdown set wavelength upon startup, eliminating the need for repetitive settings
5. Supports user self-calibration and relative value measurement: comes with an offset self-calibration function, adjustable within ±5dB range, flexible measurement
6. Supports relative value measurement, meeting comparison test requirements, with stable measurement accuracy
7. Soft rubber anti-slip cover + ABS body, can withstand a 1-meter drop
8. Large screen with backlight, clear reading even in dim environments, automatically shuts down after 10 minutes of inactivity to save power
