Learn about optical networking with Smartoptics

Welcome to this set of self-study tutorials on optical networking presented by Smartoptics.

Whether you are a newcomer to the communications field, or have already been procuring, using, or selling optical networking equipment for some time, we believe these short sessions of about 5-10 minutes each will help you feel comfortable with the terminology and principles of optical networking.

Each tutorial can be studied on its own, but if this is your introduction into the optical space we recommend starting from top down. This will take you from the fundamentals of optical transmission and wavelength multiplexing to things like how to calculate optical budgets and how to construct high-capacity networks carrying voice, video and data.

So, pick and choose your subjects and let’s get started!
