Optical Fiber Ranger OTDR Principle Tester Meter FTTx Network Fiber Optic FTTH Tool Kit Visual Fault Locator Applications: Testing the distance of the fiber and identify the faults location in the fiber link. Locates reflective and non-reflective breaks in the fiber network. Inspection of fiber repair and maintenance. 1. Before testing, ensure that the test connector and the interface clean OTDR (moistened with alcohol wipes to clean) and OTDR coupled with good test line can not be connected with the light emitting device (optical fiber can not light). 2. If you need to test the line with pigtail connection test (butt welding or ligated, flange coupling), should pay attention to the connection line attenuation can not be too large, otherwise affect the test. 3. The left side of the interface simple OTDR red light, the right to test the break interface; the interface connected to the right of the OTDR test, and then press the power button, then press the SCAN button, the screen display ||||||||| |||||| scroll bar, scroll completion can be measured readings. The first and second step is very important, if the test result screen is null, should pay attention to whether the steps 1 and 2 did not do. Wavelength: 1310/1550nm Fiber Type: 9/125um Connector Type: FC/PC Sensor Type: InGaAs Laser Peak Power: ≥60mW Maximum display distance: Reflection event： 60KM (≥1dB) Non-reflective event: 20KM(≥2.5dB) Unit of measurement: M Reflection time dead zone: 15M Distance Accuracy (Reflection Event): ±（2m+2*10-4distance） VFL: 650nm VFL power: ≥1mW Power Supply: 3pcs 1.5V AA alkaline batteries(Not include) Battery operating time: ≥5000 measurements Operating temperature: -5~40℃ Storage temperature: -10~60℃ Humidity: 0~85% Not condensing Weight(Without batter): 350g
