Multi-Service Convergence in Large Parks: One All-Optical Network for Surveillance, Broadcasting, Access Control and Office Services

As industrial parks, manufacturing campuses and corporate headquarters advance digital transformation, they need to support a growing variety of services on-site. Office PCs, Wi-Fi, video surveillance, access control systems, IP broadcasting, conference systems and IoT devices all demand stable network connectivity.

However, under the traditional park construction model, separate networks are deployed for different services: one dedicated security network for surveillance, one office network for staff, plus independent deployment for access control and broadcasting. As parks expand, wiring becomes increasingly tangled and the number of devices surges. This leads to redundant investment, while complicating later O&M, capacity expansion and cross-system service linkage.

For large-scale parks, the core of future network construction is no longer adding more independent networks. Instead, operators can deploy a unified all-optical network to realize converged multi-service bearing, while ensuring stable operation and isolation between different services.

I. Hidden Costs of Multiple Parallel Networks

Redundant construction investment
Separate cabling is required for each system: PoE cables for surveillance, control cables for access control and audio cables for broadcasting. Four systems require four separate construction teams, and cabling alone accounts for a large proportion of the project budget.

Exponentially increased O&M complexity
Each system comes with its own management portal, account credentials and troubleshooting workflows. When a network fault occurs, engineers first need to identify which system has failed before contacting the corresponding vendor. More equipment means more fault points and blurred responsibility boundaries.

Difficult cross-service linkage
Fire alarm and broadcasting run on separate systems, so emergency broadcasts cannot be triggered automatically. Door intercom and front-desk phones operate independently, so the front desk may not receive notifications when visitors ring the doorbell. Without a unified communication foundation, cross-system linkage can only rely on manual coordination.

II. One All-Optical Network to Carry All Services

AINOPOL’s solution leverages a single fiber network to carry all services, with slicing isolation to ensure different services run on independent logical channels.

One unified physical network
The all-optical network adopts a two-tier architecture of OLT plus passive optical splitters. A single fiber runs from the machine room to end points, and optical terminals provide data, voice, video and control interfaces. Surveillance cameras, broadcast speakers, access controllers, office PCs, IP phones and wireless APs can all connect to this unified optical network. Tasks that previously required four separate cable sets can now be fulfilled with one fiber infrastructure.

Logical isolation for independent services
PON hard slicing and VLAN logical isolation divide independent security domains for surveillance, broadcasting, access control, office and voice services. Different service domains are isolated by default; cross-domain access is only permitted after policy approval. Bulk file downloads in office areas will not consume bandwidth for surveillance video backhaul, and visitor terminals cannot access the access control network. One physical network delivers multiple independent logical networks without mutual interference.

Foundation for cross-system linkage
When all systems run on the same network, service linkage becomes straightforward. Built on the SIP protocol, AINOPOL’s converged communication platform integrates IP phones, IP broadcasting, video intercom and access control terminals into one unified scheduling system. When a fire alarm is triggered, the system can automatically activate evacuation broadcasts, unlock emergency exit doors and pop up relevant surveillance screens. This capability of one-time orchestration for multi-system linkage was nearly impossible to achieve under the old multi-network model.

Simplified O&M
One network managed via one unified platform for centralized management of all devices. The EAAS cloud platform supports automatic topology discovery, real-time fault alerts and one-click remote repair. Device status is visualized on a single dashboard, and fault location is shortened to minutes. Instead of assigning dedicated staff to manage separate systems, one operator can oversee the entire all-optical network.

The converged all-optical network reduces construction complexity through unified architecture, guarantees stable operation via service isolation, and improves O&M efficiency with intelligent management.

For large industrial parks, manufacturing campuses and corporate headquarters, the value of all-optical networks goes far beyond replacing traditional cabling. It serves as the infrastructure supporting continuous expansion of digital park services in the future.

From office work and security monitoring to access control, broadcasting and future IoT access, converged, secure and scalable all-optical networks are becoming the new standard for large park network construction.

FAQ

Q: Will surveillance, broadcasting, access control and office services interfere with each other when running on one network?
A: No. Hard slicing and VLAN logical isolation divide independent security domains for each service type. Service domains are isolated by default, and cross-domain access requires policy approval. Heavy office traffic will not occupy surveillance backhaul bandwidth, and visitor terminals cannot reach the access control network.

Q: If multi-service convergence is adopted, will a network failure take down all systems?
A: No. The all-optical network replaces active switches with passive optical splitters, drastically reducing fault points. Failure of a single ONU only affects one endpoint and will not bring down the whole network. The core OLT supports dual hot standby and Type B/C dual-homing protection, achieving automatic failover within 50ms for link faults.

Q: How many types of services can one optical network support?
A: It can simultaneously carry office internet access, video surveillance, IP voice, public broadcasting, access control, information release, wireless access and IoT devices. With VLAN and slicing isolation, different services run independently on the logical layer without mutual interference.
