Public Security Optical Transmission Private Network Solution

I. Project Background & Requirements Analysis  

With the advancement of the "Technology-Enhanced Policing" strategy and the comprehensive development of "Safe City" and "Smart Policing" initiatives, modern public security operations increasingly rely on communication networks. Critical services such as video surveillance, video conferencing, police telephony, and electronic licenses/traffic management form the neural network for police command, investigation, management, and services. These services impose stringent requirements on the carrier network:  

1. High Bandwidth & Stability: Large-scale access and real-time transmission of HD/UHD video surveillance require ultra-large bandwidth and high stability.  

2. Security & Reliability: Police information involves national security, requiring multiple physical/logical isolation and encryption mechanisms.  

3. Low Latency & Synchronization: Services like police telephony and command dispatch demand minimal transmission delays.  

4. Multi-Service Integration: A unified network capable of carrying video, voice, and data services efficiently.  

II. Solution Design  

FHOLINK's solution adopts an OTN+PTN integrated architecture to build an efficient, secure, and intelligent optical network:  

1. Hierarchical Network Architecture:  

   - Core Layer: High-capacity OTN equipment at provincial/municipal hubs for T-bit level transmission.  

   - Aggregation Layer: OTN/PTN fusion equipment at district/county nodes for traffic convergence.  

   - Access Layer: Multi-service PTN and industrial Ethernet switches for last-mile coverage.  

2. Service Bearer Scheme:  

   - Video Surveillance: GE/10GE optical interfaces with QoS and <50ms ring protection.  

   - Video Conferencing: E1/ETH dedicated lines for low-latency transmission.  

   - Police Telephony: TDM/VoIP carriers for secure voice communication.  

   - Data Services: Secure channels for electronic licenses/traffic management systems.  

III. Core Value & Advantages  

1. Carrier-Grade Reliability: Dual-node/dual-route design with <50ms failover.  

2. End-to-End Security: Fiber inherent security + VLAN/MAC/ACL/encryption technologies.  

3. Intelligent O&M: Unified NMS for topology management, fault alarm, and performance monitoring.  

4. Smooth Evolution: SDN-ready architecture for future 5G policing and IoT applications.  

IV. Summary  

FHOLINK's solution provides a solid communication foundation for modern policing, supporting current services while enabling future "Smart Policing" development. It is an ideal choice for public security agencies undergoing technological transformation.
