Fiber Testing Using OTDRs
Welcome to the VDV Works Virtual Hands-On Tutorial on OTDRs - Optical Time Domain Reflectometers. These instruments are valuable tools for testing and troubleshooting fiber optic cable plants, but they can also give erroneous data if used improperly. This course is intended to help you learn how to use these instruments correctly.
This "Virtual Hands-On" tutorial is designed to teach you how to set up tests with OTDRs, take data and analyze the results. If you are not familiar with OTDRs, you should study our Understanding OTDRs tutorial first, as that will make this module much easier to understand. If you are new to fiber optics, start with our basic Lennie Lightwave tutorial.
This course for OTDRs was written in reference a PC-based OTDR. Specific instructions for setting up the OTDR and accessing menu commands within the software will be shown with this product, however all of the facts concerning how tosetup and use the OTDR, analyze a trace and adjust parameters for collecting data will work in any OTDR application.
VDV Works offers an OTDR Simulator that uses the same software used to create this program and incluses over 75 unique traces to show you how the OTDR parameters should be set and the effect of various analysis methods, plus about 40 traces of real world cables.  The OTDR Simulator is available as a self-study program or an instructional curriculum. Here are ordering details.
You can download a free demo of the OTDR simulator and use it to follow these tutorials. 
How a VDV Works Virtual Online Program works
Each page of a VDV Works Virtual Online Program has a navigation bar at the side of the page that shows you the steps in the program. You should follow the program in order to get the full benefit of the course, but you can easily link back to previous lessons for reference. In the future, use the navigation bar to find the section you want quickly. In the Cable U Virtual Online Programs, a process is broken into small steps appropriate to the program. Each page consists of photos and descriptions of the steps with links to other pages for additional information that is relevant. When you are through, take the quiz to see how well you did in the course and identify areas you should retake.
