Introduction
In the rapidly evolving world of telecommunications, the demand for faster and more reliable internet connectivity continues to grow. Fiber-to-the-Home (FTTH) technology has emerged as the gold standard for high-speed data transmission, and at the heart of this infrastructure lies the Optical Network Unit (ONU). Among these, the Micro ONU stands out as a compact, efficient, and cost-effective solution, designed to meet the needs of modern networks.
This article explores the concept, features, benefits, and applications of Micro ONUs, highlighting their critical role in the future of broadband connectivity.
What is a Micro ONU?
A Micro ONU (Optical Network Unit) is a compact device that connects end users to the Optical Line Terminal (OLT) in an FTTH network. It serves as the interface between the fiber optic network and the user’s premises, converting optical signals into electrical signals for use by home or business devices.
