What is an ONU Router?
An Optical Network Unit (ONU) serves as a crucial bridge between the fiber optic network and end-user devices. Located at the customer premises, the ONU converts optical signals into electrical signals, facilitating internet connectivity. These devices are pivotal in Fiber to the Home (FTTH) deployments and play a significant role in high-speed data delivery.
Understanding the Functionality of ONU Routers
ONUs perform several key functions:
- Signal Conversion: They convert optical signals to electrical signals for devices like computers and routers.
- Connection Management: ONUs manage connections between multiple devices, ensuring efficient data flow.
- Quality of Service (QoS): They help maintain network performance by prioritizing certain types of traffic, enhancing user experience.
Types of ONU Routers
