Optical Fiber

rahulkhanna

Hello, e14 community, 

I'm about to dive into a challenging yet thrilling project. I'm planning to build a custom OTDR (Optical Time-Domain Reflectometer) for optical fiber testing and diagnostics.

I recognize that this is a complex endeavour that requires the collective knowledge and expertise of experienced individuals like you.

I'm here to seek guidance, advice, and insights from those who have walked this path before. Whether you have experience in optical engineering, fiber optics, signal processing, or related fields, your experience could be invaluable to me.

I'm eager to discuss various aspects of this project, from selecting the right components and designing the system architecture to addressing the technical challenges and optimizing performance. Together, we can explore different approaches, share best practices, and troubleshoot any hurdles that may arise during the development process.

If you've worked on similar projects or have a passion for optical technology, I'd love to connect with you. Let's collaborate, exchange ideas, and contribute to the advancement of optical fiber technology through this exciting project.

I look forward to engaging in meaningful discussions with all of you.

  • Welcome to e14.  I personally can't advise you Fibre.  Perhaps someone else can though.

  • This is a complex, time consuming, and probably very expensive project to take on.  I would suggest starting with a look at whatever documentation you can find from the major OTDR manufacturers (EXFO, Fujikura and Viavi to name a few I"m familiar with). This will give you plenty of info on the basics of OTDR operation and the building blocks you'll need.

    However, the first step is to narrow down the scope by defining the use case for your OTDR. What types fiber will you be testing, and how long are the spans you want to test? For example you would need a specialized OTDR to test the short lengths of fiber typical in aeronautic or marine applications and a different OTDR for the very long links in the cross-country networks used by communications carriers.
