High-Definition Video Transmission Demands: With the proliferation of 4K/8K surveillance cameras, bandwidth requirements per video stream have surged from 2Mbps to over 20Mbps. Traditional switch networks struggle to handle the concurrent transmission of hundreds of HD video streams across the hospital.
Sudden High-Bandwidth Impacts: Medical data volumes such as CT/MRI images and pathology slides are exploding (a single case can generate 300+ CT images), competing with surveillance video for network resources, resulting in video lag and slow image loading.
Limited Scalability: Hospital departments are frequently reconfigured (such as ICU bed expansions). Adding new surveillance points requires rewiring and additional switches, with lengthy construction periods that disrupt normal medical services.
High Maintenance Costs: Traditional networks have numerous active devices with scattered failure points. Local technical expertise is often scarce, making fault diagnosis time-consuming and labor-intensive.
Huawei's Optical Campus Solution, based on 50G PON technology, provides a new paradigm of "fiber direct to the point, simplified architecture, and intelligent operations" for Latin American hospital surveillance systems, helping healthcare institutions build efficient, reliable, and evolvable smart security systems.
Huawei's all-optical network adopts a two-tier flat architecture using OLT (Optical Line Terminal) + ONU (Optical Network Unit), replacing the traditional multi-level switch cascade model. The core OLT equipment is deployed in the central computer room, connecting to ONU terminals throughout the hospital campus via passive optical splitters, with fiber running directly to surveillance points in wards, consultation rooms, corridors, and more. This architecture offers the following core advantages:
50G PON Technology: Provides symmetrical bandwidth of 10Gbps per wave, with future smooth upgrade to 50Gbps, meeting bandwidth demands for 4K/8K surveillance video, AI-powered analysis, and real-time medical image transmission.
Low Latency Guarantee: 50G PON matches local storage speeds, reducing latency by up to 10 times, ensuring critical surveillance feeds (such as ICUs and operating rooms) are free from lag and packet loss.
Passive Optical Network: Eliminates the need for active devices between the OLT and ONU, significantly reducing potential failure points. Supports Type B/C protection mechanisms, automatically switching trunk fiber or OLT ports in case of failure, ensuring 7×24 hour uninterrupted surveillance system operation.
Fiber Interference Immunity: Optical fiber is immune to electromagnetic interference, making it suitable for complex hospital environments (such as near MRI rooms or high-voltage substations). Transmission distances can reach over 20 kilometers, covering large hospital campuses.
Network Segmentation and Isolation: VLAN or VPN technologies strictly isolate the surveillance network from medical data networks and office networks, preventing lateral attack propagation.
