With the nationwide expansion of the "Xueliang Project" (Sharp Eyes), accelerated smart city construction, and explosive growth in public security digital transformation, city-scale surveillance and video private networks are undergoing a comprehensive upgrade from SD to HD, and from passive monitoring to AI-driven intelligent analysis. JH Optoelectronic serves safe city, smart policing, and public security sectors with industrial-grade optical communication solutions spanning the entire public security video private network — including 10G/25G industrial-grade SFP+ optical modules, CWDM/DWDM WDM modules, fiber transceivers, and optical terminal core components. Our products meet the stringent requirements of traffic checkpoints, traffic management, face recognition, and long-range surveillance for high bandwidth, low latency, and high reliability. The full product line supports -40°C to 85°C industrial operating temperature range
▲ Public Security Central Management Platform → Video Private Network Core Switch → Front-end Access Switch → Public Security Monitoring / Face Capture Terminals (10G SFP+ 1310nm Industrial Solution)
Deployed at the municipal Public Security Bureau command center and cloud data center, core switches form a dual-star redundant topology. JH's 10G/25G SFP28 LR/SR modules deliver high-speed interconnection between core layer devices, with 40G/100G QSFP28 uplink modules connecting to metro backbone networks. VSS/VPC virtualized stacking enables cross-device link aggregation and seamless failover, ensuring 7×24 uninterrupted operation of the command dispatch platform.
District/county bureau and police station aggregation nodes responsible for aggregating and forwarding all frontend camera video streams within their jurisdiction. 10G CWDM/DWDM multiplexing carries multiple HD video streams on a single fiber, saving over 80% of fiber resources. JH's 10G SFP+ CWDM series (18 wavelengths) supports multiplexing eighteen 10G signals on one fiber — perfectly matched to large-scale video access scenarios.
The edge network layer closest to cameras and sensors, including roadside access switches, PoE switches, and fiber media converters. JH's JH-10G-LR-10 industrial SFP+ module is purpose-built for harsh outdoor environments with -40°C to 85°C operating temperature range, 1310nm wavelength over 10km transmission distance — meeting long-term stable operational requirements for traffic checkpoints, red-light enforcement, face capture, and other outdoor equipment.
Vehicle capture and license plate recognition systems at urban arterials and highway entrances requiring 24/7 stable operation. 10G industrial modules ensure real-time backhaul of each 1080P/4K HD stream. Edge computing gateways enable local plate recognition and violation detection, offloading backend storage and analysis.
Face capture cameras deployed at transit hubs, malls, schools, hospitals, and other key areas transmit face images in real-time via the video private network to backend AI analysis engines for blacklist matching and trajectory tracking. 10G bandwidth ensures millisecond-level multi-channel 4K face image backhaul, supporting concurrent face searches at thousand-person scale.
A city brain traffic subsystem integrating traffic flow monitoring, adaptive signal control, congestion warning, and emergency green wave coordination. Roadside sensing devices connect to the traffic network via industrial optical modules, uploading vehicle count data to the cloud every second. AI algorithms dynamically optimize signal timing, improving road throughput by 15%-30%.
Long-focal-length PTZ cameras and thermal imagers deployed at commanding heights for panoramic or border-line continuous surveillance. In long-distance scenarios, 10G ER/ZR modules support 40km-80km repeaterless backhaul. Combined with auto-zoom tracking and fire/smoke detection AI, building a "see clearly, see far, see comprehensively" three-dimensional defense system.
Integrated surveillance and access control solution for educational institutions and healthcare facilities. Campus coverage spans teaching buildings, dormitories, cafeterias, and playgrounds; hospital coverage includes lobbies, OR corridors, pharmacies, and warehouses with 7×24 recording. POL architecture reduces cabling costs — a single optical network carries surveillance, Wi-Fi, and telephony services.
River/lake/reservoir hydraulic monitoring, water quality sensing, and illegal sand dredging alerting; industrial park perimeter defense, hazardous material warehouse surveillance, and fire safety linkage. Underwater cameras connect to shore-side switches via waterproof optical modules; perimeter IR beam sensors and vibration fiber optic cables interface through industrial optical terminals — achieving integrated land-water-air security protection.
Full product line supports -40°C to 85°C operating temperature range, adapted to extreme cold in Northeast China, scorching heat in South China, and high-altitude hypoxic environments.
10G/25G industrial modules provide wire-speed forwarding with per-port throughput of 10Gbps/25Gbps and end-to-end transmission latency below 1ms, satisfying real-time HD video backhaul and AI inference analysis timing requirements. Supports IEEE 1588v2 Precision Time Protocol for nanosecond-level clock synchronization across multiple video streams.
Supports OLP optical line protection 1+1/1:N switchover — upon primary link failure, automatic backup route switching within 50ms with zero dropped frames or stuttering. OPM power monitoring provides real-time attenuation alerts for predictive maintenance before unexpected outages occur.
Modules fully interoperable with mainstream video surveillance vendors including Huawei, Hikvision, Dahua Technology, Uniview, and Kedacom across switches, NVRs, codecs, and optical terminals. Standard SFP+/SFP28 form-factor plug-and-play without custom development, significantly shortening project delivery timelines and integration debugging time.
Full-range industrial certification — operates stably from extreme cold Northeast to tropical heat, ideal for outdoor pole-mounted deployment
10G SFP+ LR/SR/ER/ZR full distance coverage — single port carries sixty-four 1080P or sixteen 4K video streams
18-wavelength CWDM scheme — one fiber replaces eighteen independent fibers, saving over 80% of conduit resources
End-to-end transmission below 1 millisecond with IEEE 1588v2 precision timing sync for frame-perfect video synchronization
OLP 1+1 optical line protection with 50ms failover — zero-interruption video surveillance experience during link failures
