FTTH Optical OTDR Tester

OTDR (Optical Time Domain Reflectometer) is an intelligent optical fiber communication tester. This tester is easy to use and portable, which has a 3.5-inch color LCD touching screen. It also possesses events intelligent analysis and more user—friendly operation.

It is an ideal test instrument for the fiber testing and troubleshooting. It can test the length of optical fiber and optical fiber cable attenuation coefficient. It can exactly display the loss distribution curve of the optical fiber and cable as well as the loss between two points and the joint loss. It also can test the distance between two points and the position of joint, fault point as well as breaking point. This tester has VFL (Vision Fault Locating) system. So it becomes convenient to test the fault location of jumper wire.


1.More accurate and better repeatability

2.List Max 8 results of each test

3.Easy to identify the faults location

4.Built-in visual fault locator with optional output power

5.Optional interchangeable connector

6.More than 10 hours long battery life


1.Testing the fiber length and locate the faults

2.Locates the distance between two connection points

3.Installation, maintenance and fault location of FTTX and Access Network
