In modern network infrastructure, FTTH technology has become the mainstream solution for high-speed broadband access. As a key device in FTTH networks, the ONU is responsible for converting optical signals into electrical signals that can be used by users.

Fiber optic technology has revolutionized communication systems, enabling faster and more reliable data transmission over long distances. Fiber optics use light to transmit data through a glass or plastic strand, significantly improving bandwidth and reducing signal degradation compared to tradition
