The All-Optical Reception Hall Built for Island Enterprises, Rising Along the East China Sea

Above the East China Sea, the waves of the Zhoushan Archipelago roll on day and night. On the island home to Zhoushan Yatai Ship Repair & Construction Engineering Co., Ltd., a 300,000-ton dry dock and a 150,000-ton dry dock stand side by side, where giant vessels take shape through sectional assembly inside the docks.

Between the dry docks and the wharf rises an on-site reception hotel built for visiting guests. It provides accommodation, catering and business negotiation services for partners, ship owners and staff. Serving as a reception hub beyond the production zone, it functions as the enterprise’s business calling card.

I. Building the Hotel on the Island: Three Core Construction Challenges

As a new-build project, Yatai Reception Hotel was free from legacy infrastructure constraints, yet it had clear performance benchmarks. During solution discussions, the project owner laid out detailed requirements for network and services. These three demands stemmed directly from real-world reception scenarios.

Full-featured services with integrated user experience

The owner specified that guest rooms must support three basic services: on-demand TV, in-room telephone service, and stable internet access for guests’ mobile phones and laptops. Furthermore, intelligent functions should be seamlessly integrated. Guests can control lights, curtains and air conditioners via the room control panel. TV on-demand, housekeeping calls and telephone answering are consolidated on one unified interface, so guests do not need to switch among multiple devices and systems. Beyond complete functions, a smooth, effortless experience is the real priority for this high-end reception venue.

Seamless connectivity while moving across premises

The owner required zero disconnection or reconnection as guests move from lobby check-in, through elevators and corridors to guest rooms. Video calls should remain frame-stable, remote work uninterrupted, and meeting screen projection available without repeated login. Reception services hinge on ease and composure, and subtle flaws in user experience are most noticeable in these details — a point the owner emphasized greatly.

Compliant and traceable internet access for external visitors

Though the hotel is primarily for internal receptions, most visitors are external guests. The owner mandated real-name authentication and log retention for internet access, as required by the Cybersecurity Law and Ministry of Public Security Decree No.176. Boundary protection was also required at the network egress to establish a trusted security barrier separating guest internet traffic from the enterprise internal network.

II. All-Optical Deployment: Delivering the Tailored Island Solution

Upon awarding of the project, the AINOPOL (Zhihui Guangxun) team visited the island for on-site surveys and held face-to-face discussions with the project owner. The team carefully worked through three core requirements: guest room functions, public-area wireless roaming and internet compliance for external visitors. A complete tailored solution was finalized for this island reception hotel:

1. Fiber-to-Room, Converged Services on One Network

Optical fibers run from the equipment room directly to every guest room. Instead of building separate networks for TV, telephone and internet services, all three types of traffic are carried on this unified all-optical network.

Made of glass, optical fiber is immune to electromagnetic interference and resistant to salt spray and high humidity on the island. It outperforms copper cables in transmission distance and bandwidth headroom. Once deployed, it leaves ample capacity for years of service upgrades for the hotel. No separate racks are required in the computer room for three independent systems, simplifying cable and device layout. New services can be added on the existing network later without building new infrastructure from scratch.

Leveraging this all-optical network, the integrated gateway ZH-H200(Ultra) installed in guest rooms connects with Jxun room control panels. Guests can operate TV on-demand and submit service requests directly via the panel. Telephone and TV services are interlinked, delivering an invisible yet seamless smart experience.

1. Composite Optical-Electrical Cables for Long Range, Seamless Roaming

Ceiling-mounted APs in public areas such as lobbies and corridors are powered and connected via composite optical-electrical cables. Within one single cable, optical fiber transmits data while copper cores supply power. One cable handles both network connectivity and power delivery, freeing remote access points from the need for nearby power outlets. Wiring stays neat and concealed above ceilings, with devices hidden from sight to balance aesthetic appearance and full wireless coverage.

With centralized AP orchestration, the network automatically performs handover in the background as guests move between the lobby, corridors and guest rooms. The transition is completely transparent to users with no disconnection or reconnection. From check-in to entering the guest room, one single network stays online continuously.

1. Real-Name Authentication + Log Retention + Firewall

through a Portal web authentication gateway in just a few simple steps without compromising usability. The backend ensures matched identity information for full traceability. Internet activity logs are fully retained and encrypted for tamper-proof storage and retrieval. In the event of security incidents or disputes, complete records can be exported anytime for traceability and evidence collection.

The Dream Gateway ZH-M1 firewall is deployed at the unified network egress to bidirectionally inspect and filter inbound and outbound traffic. It identifies and blocks external attacks, intrusions and virus propagation in real time, building a trusted security boundary separating guest internet and the enterprise internal network. Compliance and security capabilities are delivered natively together with the network architecture, making regulatory adherence a foundation of daily operation rather than a remedial afterthought.

Today, sailors returning from long voyages can plug in Ethernet cables or connect to Wi-Fi upon check-in. On-demand TV and direct-dial phones are readily available. With fiber reaching each room, all services are easily accessible. Video calls remain stable while guests walk from guest rooms to negotiation zones. Ship owners can adjust room settings via the in-room control panel. Within the front-desk system, the identity and access records of every network user are fully traceable. Ceilings in corridors and the lobby remain clean and uncluttered, preserving unobstructed sea views from every window.

For Yatai, the value of this network extends far beyond “internet access”. The triple-play converged architecture enables smooth service expansion alongside business growth. Neat wiring integrates the reception space with the corporate brand image. Seamless roaming and in-room automation eliminate the rough feel of temporary accommodation for visitors. The compliance framework allows the enterprise to host guests from all over with confidence. Much like the dry docks and wharves, this network forms part of Yatai’s reception capacity — the docks repair vessels, while the network serves people.

Tides wash over the tidal flats twice every day. Ships arrive and depart on their schedules. But this network laid inside the building knows no tides. It stands ready, waiting for the next vessel to berth and every guest aboard.
