Скачать или смотреть 2.2 Fiber Optic Basics| Explained - Attenuation, Dispersion & Non-Linear Effects|

In this video, we break down the key factors that affect the performance of optical fiber communication systems — from signal loss to distortion.

You'll learn:
🔹 What is attenuation and how it impacts signal strength
🔹 The different types of dispersion (modal & chromatic) and their effects on data transmission
🔹 Common non-linear effects in fibers like SPM, XPM, Four-Wave Mixing, and Raman/Brillouin scattering


If you're working with DWDM systems, long-haul networks, or just getting into fiber optics, this video will help you understand the physical layer challenges of modern communication.
