Optical Fiber Identifier/Live Fiber Identifier/Dark Fiber Identifier with VFL

Optical Fiber Identifier/Live Fiber Identifier/Dark Fiber Identifier with VFL Product Description  AFL-400 Optical Fiber Identifier Description   Optical Fiber Identifier can quickly identify the direction of transmitted fiber and display the relative core power without interrupting the current service. The fiber identifier recognizes modulation like, 270Hz,1KHz and 2KHz with continuous audible tone. There are four adapter heads available: Ø0.25, Ø0.9, Ø2.0 and Ø3.0. This OFI is powered by 2 pcs very normal AA batteries.   Features Easy-to-use with “ONE KEY” operation; Efficiently identifies the fiber transmission direction and frequency tone (270Hz, 1KHz, 2KHz) with audible warning; Displays the relative core power;  Easy-to-replace adaptors;  Durable metal housing and quality construction; Lower power indication. It's easy to carry and loss adaptors can be avoided with new adaptors box.   Specifications

--- 1).the electrodes are aging,you need to change new ones
--- 2).the electrodes are not installed very well,you need to re-install and fix the electrodes well.
--- 3).discharging current is not good,you need to do discharging experiment to make the current get the right point

7.splicing machine shows loss is not large,but it's larger when testing use a OTDR,what causes?how solve?
--- 1).the electrodes are aging,you need to change new ones
--- 2).discharging current is not good,you need to do discharging experiment to make the current get the right point
--- 3).Optical fiber end face is bad,there is something wrong with the cutting blades.You need to adjust the fiber cleaver & cutting blades to make sure end face is better
--- 4).There has dust in V groove,you need to clean V groove,microscope,electrodes etc
