Goilips Ultra-Long-Reach Smart City Surveillance Solution for Sharp Eyes Projects

Overview

The construction of Sharp Eyes projects and smart city security systems requires all-weather, no-blind-spot coverage across urban roads, inter-district boundaries, rural intersections, and remote border-defense areas.

With the widespread adoption of 4K/8K ultra-HD surveillance cameras, front-end video backhaul demands high bandwidth, long reach, and stable reliability. For tens or even hundreds of kilometers of backhaul, traditional solutions often require active relay boxes every 20km to 40km, including protective enclosures, switches, and power facilities.

This solution uses Goilips 1.25G/10G 80km-120km ZR ultra-long-reach high-power optical modules. With high-sensitivity receivers and EML/APD optical designs, it builds zero-relay point-to-point optical channels that remove dependency on intermediate active sites and provide cost-effective, low-maintenance backhaul for smart city surveillance.

Applications

Inter-District Highway Surveillance

For ultra-HD video and license-plate recognition data backhaul across suburban counties, highway border toll stations, and inter-district security checkpoints.

Rural and Border Video Surveillance

For village entrances, forest fire monitoring, coastal defense, and border-line video sensing networks where relay-site power is unavailable.

Sharp Eyes Project Backbone

For direct aggregation of distributed camera video streams from wide geographic areas to municipal or county public-security command centers dozens of kilometers away.

Deployment & Architecture

Remote 4K/8K cameras connect to industrial optical transceivers or access switches equipped with Goilips ZR modules. A single-mode fiber directly connects to the city or county command center without any intermediate active amplification or relay equipment.

Zero-Relay Architecture

Core Deployment：Removes intermediate active relay boxes, relay switches, and waterproof power-distribution facilities.

Advantage：Eliminates failures caused by relay-site power loss, high temperature, lightning, or aging, improving link MTBF by multiple times.

Anti-Dispersion and DDM Diagnostics

Core Deployment：Built-in dispersion-tolerance circuits, TEC wavelength locking, and real-time DDM monitoring for optical power and temperature.

Advantage：Suppresses dispersion penalty over 80km-120km links and helps operators locate optical faults hundreds of kilometers away.

Key Benefits

1

Lower Construction CapEx

Eliminates all intermediate active relay sites, avoiding land rental, dedicated power-line construction, and relay switch procurement, reducing total project cost by more than 40%.

2

Lower Operations and Maintenance OpEx

Zero intermediate active nodes mean no routine patrol or power maintenance for relay sites. Troubleshooting focuses on the two endpoints, improving maintenance efficiency by more than 70%.
