Product Description body { font-family: Arial, sans-serif; line-height: 1.6; } h2 { color: #333; } ul { list-style-type: disc; margin-left: 20px; } Product Features Transmitter Testing Function: Includes capabilities such as cable continuity testing, cable scan, port flashing, cable length measurement, PoE testing, and QC testing for crystal heads. Also features Optical Power Meter (OPM) and Visual Fault Location (VFL) functions. PoE Test: Automatically identifies midspan, endspan, and power by 8 cores. It also distinguishes between standard and nonstandard devices. Optical Power Meter: Offers wavelength switching for 850/1300/1310/1490/1550/1625nm, with units available in dBm, dB, mW, µW, and nW. Also includes a REF switch. Visual Fault Location Function: Detects and locates fiber breaks, poor connections, fiber bends, or cracks. Receiver Function: Features sensitivity adjustment, 300m no-load shielded network cable support, NCV detection, and a lighting function for better visibility. Non-contact Voltage Detecting: The receiver can detect AC voltage in household electrical wiring. Illumination Function: Equipped with a lamp for auxiliary lighting during operation. Battery Operated: Both the transmitter and receiver include a 1500mAh polymer battery, eliminating the need to change batteries. Features Type-C charging with charging and low battery indicators. Other Settings: Includes adjustable backlight brightness and time, auto-off settings, and flashing red light options under VFL function. Wide Applications: Suitable for network line engineering and maintenance in telecommunication, computer, and other metal conductor tasks.
