Huawei’s FTTO Solution Accelerates Digital Transformation of Tatai Hydropower Plant in Cambodia

1. Origins

The Tatai hydroelectric power station is located on the Tatai River, 261 km from Phnom Penh, the capital of Cambodia. The station has won the “Excellent Power Generation Enterprise Award” from Electric Du Cambodia (EDC) for many consecutive years. In 2018, the Koh Kong provincial government awarded the “Award for Outstanding Social Contribution” to the resort. By 2021, the station has provided a total of over 7 billion kWh of feed energy and maintained safe production for over 2,600 days.

2. Challenges

With the development of the digital economy, the Royal Government of Cambodia (RGC) has officially unveiled the Policy Framework for Digital Economy and Society in Cambodia 2021-2035, and formulated 139 specific measures to build a digital infrastructure. Hydroelectricity production is closely linked to social development. Therefore, it is imperative to gradually improve the digital infrastructure. As a pioneer in hydropower generation, Tatai Hydropower Plant sees digital innovation on campuses as one of the main tasks of digital transformation. Currently, progress in building Cambodia’s digital economy infrastructure is slow due to lack of information and communications technology (ICT) personnel. In addition, Tatai Hydropower Plant faces the following digital transformation challenges:

  1. Insufficient network bandwidth and poor user experience: In traditional solutions, switches are cascaded and copper cables are used for transmission, resulting in slow and unstable network speed. The speed can only reach 16 Mbit/s at a distance of 100 m. Also, 90% of copper cables cannot be upgraded to gigabit cables.
  2. Difficult deployment of new services and complex construction: Several services coexist on campus, such as telephone, Internet access and HD TV. However, service systems are built separately with complex wiring. As a result, new services cannot be deployed quickly, multiple networks and devices are stacked, and network scalability is poor.

3. Customer requirements

To cope with the previous challenges, the Tatai Hydroelectric Power Station needs a future-oriented high-speed and stable network that can carry multiple services (including Internet access, emergency calls and video backhaul ). In addition, the entire network must be green and energy efficient to support the sustainable development of the hydroelectric plant.

4. Huawei FTTO all-optical campus solution

Huawei offers the innovative FTTO solution to address network challenges and meet the requirements of Tatai Hydropower Station.

This solution combines the simplified architecture of Passive Optical LAN (POL) and the advantages of IP technologies to meet campus challenges. In addition, it brings the following main advantages to the station:

  1. High-speed, stable and future-oriented network: Gigabit access is provided for terminals, ensuring high-speed and stable network access anytime and anywhere in the hydropower plant. Moreover, the FTTO solution supports smooth evolution from GPON to 10G PON and 50G PON without changing platforms. As a result, the high bandwidth requirements of massive digital applications such as information transport and emergency calls can be met in the future.
  2. Converged bearing and simplified O&M: The FTTO solution extends fiber to bedrooms to deliver HD TV services in dorms and broadband network services in offices. With this solution, multiple services are transported over a single fiber. The entire network is managed in a unified way. ONUs are plug-and-play and can be replaced immediately after a fault has occurred. This effectively improves the maintenance efficiency of the hydropower plant network and enables one person to manage a campus, thereby reducing operation and maintenance costs by 70%.
  3. Simplified Architecture and Power Saving: Passive optical splitters are used to replace active switches, simplifying the network architecture from three layers to two layers. There is no need to build ELV equipment rooms, obtain electricity, run cables, or install ancillary devices such as air conditioners and disaster prevention devices. As a result, the power consumption is 60% lower than that of traditional networks.

5. Voice of the customer

According to Wang Jiaji, Director of Information Technology Department of Tatai Hydropower Station, Huawei’s FTTO solution not only provides ultimate network experience of office and life services for Tatai Hydropower Station, but also brand a decisive step forward in the station’s digital transformation. . An industry-leading all-optical campus network without copper cables is deployed in the station. Multiple types of services are carried over a single fiber, simplifying O&M and deployment while saving energy. It also facilitates the sustainable development of the station.
