4.1 Technical Features of TS-PON Technology

TS-PON (Time-Sensitive PON, Time-Sensitive Passive Optical Network) is an innovative communication technology that combines the strengths of Time-Sensitive Networking (TSN) and Passive Optical Network (PON). Its core mechanism employs a high-precision time synchronization system to assign fixed uplink time slots to each node, enabling time-division synchronous multiple access that fundamentally prevents data conflicts while ensuring reliable transmission with low latency. Key features of this technology include:

Ø  Ultra-low latency guarantee: Supports configuring fixed bandwidth channels for camera video streams, with an end-to-end latency ≤ 2 ms.

Ø  Long-range coverage: Supports up to 20 km of fiber-optic transmission, ideal for distributed monitoring scenarios such as campuses, roads, and industrial sites, enabling wide-area deployment without repeaters.

Ø  Flexible bandwidth allocation: Offers three modes—fixed bandwidth (CIR), guaranteed bandwidth (CIR+PIR), and best-effort bandwidth—which efficiently handle mixed traffic from video streams and various signal streams while ensuring bandwidth availability for critical services.

Ø  High bandwidth and seamless evolution: Currently supports up to 10 Gbps transmission rates, with future smooth upgrades to even higher bandwidths to meet growing business demands.

Ø  Enhanced anti-interference capability: The optical fiber medium inherently resists electromagnetic interference, ensuring stable and reliable signal transmission.

Ø  Excellent scalability: Featuring a point-to-multipoint architecture that supports flexible addition or removal of nodes, making network expansion and maintenance straightforward.

TS-PON achieves high-precision time synchronization through time-slicing technology, delivering a bandwidth-efficient, low-latency, and highly reliable access solution for latency-sensitive applications such as industrial control and smart monitoring systems.

4.2 Multi-service Access Capability

The system utilizes a QoS mechanism to prioritize the scheduling of various types of traffic, providing differentiated quality assurance for different services. The supported service categories are as follows:

In video services, node devices connect to standardized network cameras via Ethernet interfaces, enabling transparent video stream transmission and uplink aggregation to the central device's upstream port. The system also supports VLAN-based service isolation and priority identification, ensuring stable video transmission performance.

The serial data service features integrated serial port protocol conversion at the node end, capable of encapsulating traditional serial data into IP packets and routing them uniformly to central equipment via the PON transmission network. The central end forwards the data to the backend data center using TCP or UDP protocols. The system supports concurrent transmission of multiple serial channels, with each channel allowing independent configuration of communication parameters such as baud rate and data bits; external adapter devices are required for practical implementation.

For industrial control applications, particularly those requiring real-time data transmission in sectors like power generation, the TS-PON system enables dedicated allocation of high-priority transmission channels, significantly reducing data forwarding latency and meeting the industry's demands for low-latency, highly reliable command transmission.

4.3 Reliability and Maintenance

The optical link diagnosis function leverages the central ROOT management node to establish a comprehensive monitoring system, enabling round-the-clock real-time online monitoring of the operational status of all remote nodes across the network. It accurately collects key optical path parameters including real-time uplink/downlink transmission power values, actual fiber link transmission distances, and real-time bit error rates at each node. The system automatically performs intelligent analysis and comparison of collected data; upon detecting various fiber optic faults such as abnormal optical power fluctuations, excessive link loss, sudden bit error increases, or optical path interruptions, it immediately identifies the fault location and type without requiring operators to conduct segment-by-segment on-site investigations. This significantly reduces troubleshooting time, enables rapid fault localization and emergency response, thereby enhancing overall operational efficiency and fault resolution responsiveness of the optical transmission network.

The NODE node remote management function provides the entire network system with comprehensive centralized operation and maintenance control capabilities for remote nodes. Administrators can exercise unified remote management over all NODE-connected nodes across the network via a central management platform, significantly reducing on-site maintenance staffing requirements, streamlining daily operation procedures, lowering field operational costs, and achieving standardized, unified management of all network devices—thereby substantially enhancing overall network operation convenience and management efficiency.

The system features a 1+1 link hot backup capability, with each device equipped with dedicated independent A and B service transmission ports that natively support the 1+1 primary/secondary link redundancy mechanism. These ports can be connected to two mutually independent physical transmission links serving as the primary and backup paths respectively. The system enables millisecond-level automatic link switching, seamlessly transitioning to the backup port to continue transmitting business data without any service interruption or packet loss, thereby ensuring uninterrupted operation of critical services such as voice communications, Ethernet data, and IoT applications while completely eliminating the risk of network-wide service downtime caused by single-link failures.

The intelligent ring network protection function ensures full compatibility of the central ROOT core device with professional ring network protection mechanisms, supporting dual PON port redundant networking modes and uplink aggregation deployment configurations. It enables rapid self-healing and reconstruction of ring network links, guaranteeing stable communication between all nodes within the ring. This protection function is deployed through dedicated system software authorization, offering flexible deployment and strong adaptability. It comprehensively enhances the overall operational stability, resilience, and emergency communication reliability of the entire optical communication system at the network architecture level, fully meeting requirements for high-reliability applications such as emergency communications and private network transmission.
