Fiber Optic Reflectometer (OTDR) with OPM, VFL, OLS & Event Map — Ethernet Cable Tester, 24/22dB Optical Fiber Tester, Accurate Measurement Data

Multi-function fiber optic tester combining an event map OTDR, optical power meter (OPM), visual fault locator (VFL), stable light source (LS) and loss test capabilities for clear, reliable diagnostics. Event map / one-key automatic test: Performs a one-key automatic scan that produces a graphical event diagram showing total link length, event types, and fault/breakpoint positions for straightforward interpretation. Optical Power Meter (OPM): Measures optical signal power and insertion loss for a variety of equipment and optoelectronic devices. (F1: Switch wavelength, F2: Set reference power, F3: Set reference power to zero, F4: Enter oscilloscope mode) VFL — Visual Fault Locator: Emits visible red light at 650nm into the fiber so leak points are visible, enabling fast and accurate localization of fiber faults. LS — Stable Light Source: The stable light source uses the same wavelength as the OTDR and is suitable for parameter checks in telecommunications, CATV and LAN optical cabling; useful for testing insertion loss, isolation and return loss of light sources and for checking detector wavelength response. Loss testing: 1310nm/1550nm light source and power meter readouts are shown simultaneously for convenient loss measurements, including insertion loss, isolation and return loss of passive optical components.
