Optical Power Meter with VFL FF-7209A 4-in-1

The FirstFiber FF-7209A is a 4-in-1 optical power meter that combines power measurement, a visual fault locator, an LED flashlight and a cable tester in a single device. One instrument covers tasks that would otherwise require several separate tools, so the technician carries just one unit to the field. The measurement section uses an InGaAs detector covering 800 to 1700 nm, with standard wavelengths at 850, 1310, 1490, 1550 and 1625 nm. The measurement range is -70 to +3 dBm with 5% uncertainty, displayed in both linear and logarithmic formats. The built-in fault locator emits a red 650 nm laser at over 5 mW to pinpoint fiber breaks. The LED flashlight illuminates work in dark conditions. The cable tester function verifies RJ45 connections, activated by a long press on the UNIT button for three seconds. The device accepts FC, SC and ST connectors. It runs on a 3.7 V / 700 mAh battery for up to 48 hours of continuous use, with automatic shutdown after 10 minutes of inactivity. Dimensions are 118 x 68 x 30 mm at 0.14 kg.
