With the development of network communication technology, PON passive optical network is gradually entering people's field of vision. PON, or Passive Optical Network, is a transmission network based on optical fiber, consisting of OLT (Optical Line Terminal), ODN (Optical Distribution Network) and ONU. ONU is a terminal device that connects users and realizes data transmission through optical fiber. ONU usually follows the G-PON (Gigabit Passive Optical Network) or XG-PON standards defined by ITU-T, which stipulate the upstream and downstream rates, frame structure, signaling protocols, etc. in optical networks.

For example:
[0005] 1: Directly use the telecommunications fiber optic modem and place it next to the cabinet. It needs to be provided with factory power and the network cable is connected to the switch port of the local network. This will make the optical modem take up space and require a separate power supply. However, the cabinets of enterprises are often very clean and tidy, and it is impossible to introduce new power sockets.
[0006] 2: Use a fiber optic modem, insert it into the fiber optic port of the switch, and use the switch fiber optic port to draw power; however, since the size of the fiber optic modem is very small, and the power consumption of the fiber optic modem chip is very large, and the fiber optic port of the switch itself is designed for high density, so far, whether it is a fiber optic modem designed by a large manufacturer or a small manufacturer, there will be excessive power consumption and unstable work, and the size of the fiber optic port is very small, making the design more difficult.
[0007] 3: Optical modems used with routers and other products require separate power supplies. Sometimes insufficient interfaces can cause inconvenience and also increase costs and energy. Utility Model Content
