[0022] like Figure 1-4 As shown, the utility model provides an optical network central office device for switching between single-wavelength, dual-wavelength and multi-wavelength. The optical network central office device for switching between single-wavelength, dual-wavelength and multi-wavelength includes:

[0023] The OLT is set at the central office to process and control the traffic of the entire network, the player is set at the user end and has the function of sending signals and receiving data, the ONU is set at the user end to provide network access services for users, and the optical transmission medium ODN is used to physically connect the ONU and OLT;

[0024] The player at the user end can manipulate the data sent by the OLT. The OLT can adjust the content and quality of the data stream based on the feedback information collected by the ONU. The video playback of the signal transmission supports two-way planning. Through two-way planning, it can respond to user requests in a timely manner and improve the quality of video playback.

[0025] The OLT device arranged at the central office includes a box 1, on which a power board 6, a main control board 5 and a plurality of service boards 4 are installed. The main control board 5 is the core part of the OLT device. The main control board 5 can receive and process data from each service board 4, and then send the data. The service board 4 is mainly responsible for processing the user's service data. It can classify and process different types of service data, convert them into optical signals and transmit them to the user-end device ONU through optical fiber. The power board 6 is provided with a power interface 7 for connecting a power line. The power board 6, the main control board 5 and the service board 4 are all plugged into the slot of the box 1 side by side. A plurality of slots are provided with air ducts 10 for convenient air circulation. The air ducts 10 are arranged in the box 1. The air ducts 10 are connected with the air inlet 8 and the air outlet 2 provided on the box 1. The air outlet 2 is arranged at the top of the box 1, and the air inlet 8 is arranged at the bottom of the box 1. The density of hot air is less than that of cold air, so the hot air will rise. The air outlet 2 is arranged at the top to accelerate heat dissipation. The air outlet 2 and the air inlet 8 are both equipped with a filter 3 for preventing dust from entering the box 1. A fan 9 is installed in the air outlet 2. The fan 9 is installed at the top of the chassis. It can extract the hot air inside the chassis faster and form a negative pressure inside the chassis. In this case, the cold air from the outside will enter the chassis through the bottom air inlet 8, thereby realizing the replacement of the air inside the chassis. The fan 9 is installed inside the box 1, and the filter 3 is arranged outside the box 1. The fan 9 can clean the dust on the filter 3. The entire exhaust device increases the exhaust speed of the hot air inside the box 1, improves the heat dissipation efficiency, and prevents the device from overheating when there are too many data flows.

[0026] Working principle: The user sends a video playback request to the OLT through a player (such as a computer). After receiving the request, the OLT converts the request into a corresponding data stream and sends it to the ONU through the ODN. After receiving the data stream, the ONU decodes it and outputs it to the user's video player to play the video. At the same time, the ONU also collects user feedback information, such as playback progress, pause / play instructions, etc., and transmits this information back to the OLT through the ODN. After receiving the feedback information, the OLT adjusts the content and quality of the data stream according to the feedback information to optimize the user's viewing experience and achieve two-way planning.

[0027] With the popularization of optical networks, the number and frequency of data transmission have greatly increased. Excessive data flow may cause OLT equipment to overheat. When processing a large amount of data flow, the power consumption of the equipment will increase, which may cause the temperature of the equipment to rise. If the equipment is in an overheated state for a long time, it may affect the performance of the equipment, and even cause damage or failure of the equipment. Therefore, it is necessary to install a heat dissipation device. The fan 9 is installed on the top of the box 1 by suction heat dissipation. When the fan 9 is turned on, the hot air inside the chassis can be drawn out faster, so that negative pressure is formed in the chassis. The cold air from the outside will enter the chassis through the bottom air inlet 8, and the hot air will be discharged from the box 1, thereby replacing the air inside the chassis and completing the heat dissipation.
