There are many types of ONUs (Optical Network Units), which are mainly classified according to their application scenarios and functions in optical fiber access networks (FTTH, FTTB, FTTC, etc.). The following are some common types of ONUs:

Ordinary family ONU:

It is used to convert optical fiber signals into electrical signals and connect them to computers, routers, TVs and other devices in the home. In the FTTH (Fiber to the Home) network, this type of ONU mainly serves residential households.

Multi-Service ONU:

It has the function of supporting multiple services, including data, voice, video, etc. This kind of ONU can usually meet the needs of different applications and is suitable for comprehensive service transmission scenarios.

EPON ONU:

Used in EPON (Ethernet Passive Optical Network) networks, it is an optical fiber access solution based on Ethernet technology. EPON ONU is suitable for providing high-speed broadband Internet access services.

GPON ONU:

Used in GPON (Gigabit Passive Optical Network) network, it is a high-speed, high-bandwidth optical fiber access technology. GPON ONU is suitable for providing higher-speed optical fiber access services and supporting a variety of services.

CATV ONU:

Used in CATV (Cable Television) network to support cable TV signal transmission. This kind of ONU can transmit TV signals in the optical fiber network and provide multimedia services.

OLT terminal ONU:

As the terminal equipment of OLT (Optical Line Terminal), it is connected to the user end and is responsible for photoelectric conversion with user equipment. This ONU is located at the terminal of the optical fiber network and communicates with the central OLT.

Wireless ONU:

With wireless communication capabilities, fiber optic network connections can be extended to wireless terminal devices, such as smartphones, tablets, etc., through Wi-Fi or other wireless technologies.

Commercial ONU:

ONUs for business users usually support larger bandwidth and more business requirements, and are suitable for office buildings, commercial areas and other places.

Each type of ONU has specific application scenarios and functional characteristics. Choosing the appropriate type of ONU depends on the specific network design, user needs and deployment environment.
