OTN Insights | Sumble

What is OTN?

OTN (Optical Transport Network) is a next generation optical transport technology that provides an efficient and globally accepted way to transport various services over optical fiber. It provides a network hierarchy for efficient transport of Ethernet, storage, and video, and is commonly used in backbone networks and high-bandwidth applications to improve network performance, flexibility, and manageability.
