The CableMaster FO is a fiber optic power meter capable of measuring seven different wavelengths. Power can be measured in decibel-milliwatts (dBm), decibels (dB) or milliwatts (mW). This optical power meter includes a visual fault locator for port and polarity detection and an attenuation meter for seven signal wavelengths in dB. To determine signal strength, the device’s power meter provides measurements in dBm and mW. It also features a flashlight to assist in dark wiring cabinets and includes a copper RJ45 patch cord tester for checking wiremaps. Designed as a pocket-sized tool, it is portable across the jobsite and features a USB-rechargeable battery capable of up to 80 hours of operation.
