01 Project Background

With the continuous expansion of the business scale of the Three Gorges New Materials Smart Factory, the demand for intelligent office is increasing day by day. Application scenarios such as high-definition video conferencing, big data transmission, and multi device interconnection have put forward higher requirements for network performance. However, traditional office networks are no longer sufficient to meet the needs of enterprise development. To this end, Three Gorges New Materials has set the goal of building an office solution based on all-optical networks, achieving network performance upgrades, efficient business integration, and safe and reliable operation, providing solid network support for the intelligent transformation of enterprises.

02 Traditional office network pain points

Complex wiring and difficult operation and maintenance

Traditional office networks use copper cable wiring, and with the increasing number of devices, network cables and telephone lines interweave into a "spider web", and weak electrical equipment is disorganized. Every time a new device is added, the wiring needs to be re planned, which is not only tedious to construct, but also requires operation and maintenance personnel to troubleshoot a large number of cables one by one, which is time-consuming, labor-intensive, and extremely inefficient.

Bandwidth bottleneck, poor user experience

In scenarios such as full staff meetings and centralized data processing, the problem of insufficient bandwidth in traditional networks is exposed. High definition video conferences often experience lag and slow file transfers. When departments conduct big data simulation calculations, network delays can even cause task interruptions, seriously affecting work efficiency. The average annual loss of office efficiency exceeds 15%.

Insufficient expansion and high cost

When enterprises build new office areas or add equipment, the drawbacks of poor scalability of traditional networks become prominent. Upgrading a network often requires replacing core switches and rewiring a large number of cables, which not only incurs high renovation costs but also affects normal office operations and slows down business progress.

03 All Optical Office Network Construction Plan

Minimalist network architecture, fiber to desktop

Adopting a "core access" flat PON all-optical network architecture, the core layer deploys OLT fiber servers, and the access layer achieves "fiber to building, fiber to workstation" through POE ONU and optical AP (wireless access point). Compared to traditional solutions, the wiring volume is reduced by 60%, and the space occupation of weak current rooms is reduced by 75%. A single fiber optic cable can carry various signal transmissions such as data, voice, and monitoring, greatly simplifying the network structure and reducing the difficulty of operation and maintenance.

Multi business integration, efficient collaboration

All optical networks support the integration of multiple services such as monitoring, data, and voice. High definition monitoring images, office data, voice calls and other different types of services are stably transmitted through the same fiber optic network, avoiding resource waste and management difficulties caused by multi service segmentation in traditional networks, and achieving efficient collaboration of services.

Elastic expansion, oriented towards the future

The passive optical distribution architecture of PON networks endows the system with strong scalability, allowing enterprises to smoothly upgrade from GPON to 10GPON or even higher specifications according to business development needs without the need for rewiring. According to the current business growth forecast of Three Gorges New Materials, this architecture can meet the bandwidth demand for the next 8 years and is expected to save over 1.2 million yuan in subsequent network renovation costs.

Intelligent visitor authentication, secure and controllable

Build a multi-dimensional WiFi authentication system for visitors. Ordinary visitors can only access the Internet by scanning WeChat codes to obtain temporary permissions; Partners can access designated shared folders after approval; Important customers can access product development documents encrypted after authorization. The system detects the security status of visitor devices in real-time, intercepts devices with viruses, and monitors visitor traffic to ensure comprehensive network security for the enterprise.

04 Network Topology

05 Product Recommendations

The all-optical office network of the Three Gorges New Materials Smart Factory adopts a typical two-level optical PON network architecture. Deploy a high-performance fiber optic server at the core layer as the aggregation and distribution center for network data, connecting key equipment such as enterprise core servers and databases.

At the access layer, optical AP devices are connected to ONUs through optical fibers to achieve Wi Fi 6 wireless network coverage in the office area; At the same time, fiber optic cables are directly laid to various workstations, providing high-speed and stable network access for wired internet devices. The telephone system is connected to the network through an IP voice gateway, achieving seamless integration with the all-optical network.

This topology structure not only ensures high bandwidth and low latency transmission of the network, but also has good redundancy, ensuring that the network can still operate normally in the event of some device failures.

06 Value Presentation

Three Gorges New Materials relies on all-optical networks to build a solid security defense line. Multi dimensional visitor authentication improves access efficiency by 80%, core data transmission is fully encrypted, and network upgrades accelerate core business by four times. Its strong scalability will anchor the development of the next decade, lay a solid foundation for the implementation of industrial Internet and other cutting-edge technologies, and become a benchmark case for the digital transformation of the industry.
