Description

Technical Field

[0001] The present invention relates to the technical field of building optical networks, and in particular to a building optical network system based on silicon photons and optoelectronics. Background Art

[0002] The building optical network system mainly includes optical line terminal (OLT), passive optical network (PON) or optical distribution network (ODN), optical network unit (ONU), etc. Optical fiber is used to replace traditional copper cables, and passive optical splitters are used to replace active aggregation and access switches to achieve efficient and stable network transmission. It can carry multiple services such as video, data, and voice, and realize unified carrying of multiple scenarios and full services.

[0003] Traditional optical network systems often use discrete optoelectronic devices, which have limited performance in the generation, modulation, reception and demodulation of optical signals, and cannot meet the needs of modern buildings for high-speed data transmission. Traditional optical network systems have bottlenecks in terminal device access, and the connection between Ethernet terminal devices and optical fiber networks is often not efficient enough, affecting the overall network performance. Many existing optical network systems lack effective management and monitoring mechanisms, making it difficult to detect and handle network failures in a timely manner, affecting the stability and reliability of the network. In high-load scenarios, traditional optical network systems are often unable to effectively allocate bandwidth resources, resulting in network congestion and performance degradation. Summary of the invention

[0004] The object of the present invention is to provide a building optical network system based on silicon photonics and optoelectronics to solve the problems raised in the above background technology.

[0010] The management layer monitors and manages the building optical network system;

[0011] The panel-type optical terminal obtains real-time load data of the terminal device through the transmission layer and determines the high-load terminal device and the low-load terminal device. The high-load terminal device and the low-load terminal device are divided into multiple sub-areas, each sub-area contains a number of optical switch nodes, and the high-load area and the low-load area are determined by comparing the load average of each sub-area with the set threshold. The panel-type optical terminal allocates bandwidth to the high-load area and the low-load area through the SDN controller.

[0012] Furthermore, the panel-type optical terminal has bidirectional 128-bit AES encrypted data transmission to ensure the security of data transmission and effectively prevent data leakage. It also supports 802.3X flow control protocol and 4 port VAN mode settings to ensure that the data flow between the transmitting and receiving nodes is stably controlled to prevent data packet loss.

[0013] Furthermore, the panel-type optical terminal sets the bandwidth demand priority of the terminal device based on the QoS rule, giving high priority to key terminal devices to ensure that they can still obtain sufficient bandwidth when the network is congested, thereby ensuring business continuity and stability.

[0014] Furthermore, the panel-type optical terminal assigns different weights to different terminal devices based on weighted fair queues to achieve personalized bandwidth allocation. By assigning weights to different terminal devices, more sophisticated bandwidth management is achieved to avoid resource waste. According to the needs and application scenarios of different terminal devices, bandwidth allocation can be flexibly adjusted to improve experience.

[0015] Furthermore, the panel-type optical terminal includes an optical module, an Ethernet PHY chip, an AP module, a wireless aggregator, a data encryption module, and a VLAN controller model.

[0016] Furthermore, the panel-type optical terminal has a memory module, which records the transmission performance, network delay, and data throughput of the optical signal;
