New AFI420S Fiber Optic Optical Fiber Identifier + 1mw Visual Fault Locator

Description

This Fiber Identifier AFI400 widely used in optical cable construction and maintenance. The use of macro bending technology To do non-destructive testing. can measure the signal direction and power, to avoid misoperation resulting in interrupted lines. Macro bending measurement, macro bends are the use of fiber-optic bending leak out when the weak optical signal, optical signal to detect the direction and intensity. Does not damage optical fiber, without interrupting communications, and direct detection of 25mm bare fiber, 0.9mm and 2.5mm fiber casing tight jumper. Tone identification, Optical Fiber Identifier can detect optical signals in the tone signal a fixed load, 270Hz, 1KHz and 2KHz, to identify a specific optical fiber, can quickly find the necessary fiber. Low battery monitoring function, when battery power is insufficient to issue instructions to remind users to change batteries.
