50G PON: A Rigid Requirement for Digital Transformation

At present, the development momentum of global fiber access is booming and it is widely used in important scenarios such as homes, campuses, cities and manufacturing. In the field of fiber access, passive optical network (PON) is the preferred dominant technology, which can achieve low latency and sustainability and meet the growing bandwidth demand. PON solutions are designed to support bandwidth upgrades while protecting the original investment, thereby achieving coexistence with earlier technologies. Today, 10G PON is being widely deployed, and its main upgrade direction in the future is 50G PON. 50G PON combines all the advantages of PON and provides future-oriented fiber access technology for communication service providers (CSPs) and smart city, campus and enterprise IT managers.

The important role of 50G PON in homes, campuses and enterprises

Home

PON is the preferred technology for fiber to the home (FTTH). As bandwidth consumption continues to grow, CSPs are committed to providing homes with higher-speed PON solutions and whole-house FTTR (fiber to the room). Although the global 10G PON upgrade is in full swing, it is inevitable to continue to evolve to 50G PON in the future. 50G PON will meet various bandwidth requirements in the future, such as:

The demand for home broadband is growing. By 2028, 44% of global consumer broadband subscriptions are expected to reach 1 Gbps or higher, compared to only 6% in 2021. Similarly, average broadband speeds will increase from 163 Mbps in 2021 to nearly 1.1 Gbps in 2028.

Smart home services are developing rapidly, and many services such as professional monitoring, video cloud storage, and smart care for the elderly require reliable, low-latency broadband.

The number of home networked devices is growing, and their functions are constantly enriched. High-quality extended reality (XR) requires 1 Gbps bandwidth and less than 3ms latency to ensure a high-quality experience.

Many residential users can work from home, and many small and micro enterprises also support home operations. Adequate bandwidth and low latency are essential for cloud applications and high-quality video conferencing, and home networks must support multiple users and multiple activities at the same time. 50G PON can meet future home connectivity needs and use FTTR to ensure sufficient bandwidth supply throughout the home.

Campuses and enterprises

Campuses and enterprises of all types and sizes rely on low-latency broadband connections and cloud-based applications. Virtualization and artificial intelligence (AI) are enhancing employees' digital and video collaboration capabilities. Various campus and enterprise environments also put forward requirements for 50G PON, such as:

Education campuses are evolving into smart campuses with digital classrooms and laboratories. Educators are using augmented reality (AR)/virtual reality (VR) applications to simulate learning and real life, which also accelerates the arrival of the metaverse. The metaverse supports collaboration between students in the same school, students in school and remote access students, or students across regions and schools. This new immersive education technology requires large bandwidth and low latency. Therefore, 50G PON will become the only choice for smart education campuses.

Manufacturing campuses require advanced digital operations to improve output, operating profits and quality while reducing resource waste and energy consumption. This type of environment, known as Industry 4.0, requires an all-optical network to quickly move and manage data between machines, factory floors, control rooms, edge and cloud. 50G PON makes this possible.

The organizational structure of the medical campus is relatively complex, including professional equipment, software, employees and patients, across many facilities. The portability and exchangeability of digital data are the basis for improving medical health, and data security is also critical. The use of advanced digital imaging technology has significantly improved medical standards. However, medical image sharing and cloud storage require high bandwidth. This also drives the demand for 50G PON in medical parks.

Smart cities require a variety of technical support such as AI, machine learning, and computer vision to achieve the coordinated operation and real-time adjustment of urban services, assets and systems, thereby providing a better and safer environment for work, life and entertainment. Smart cities can bring many benefits, including cleaner air, better traffic management, more efficient government services, and lower crime rates. High bandwidth, low latency and reliable connectivity are the most basic requirements for realizing smart city applications, which also cannot be separated from the support of 50G PON.

50G PON and Sustainable Development

Sustainability is a common goal for CSPs and IT executives around the world. PON is a sustainable broadband technology based on fiber and point-to-multipoint connections that supports multi-user and multi-application services over a single fiber strand. Higher-speed PON technologies, such as 10G PON, are increasing bandwidth while reducing the power consumed per gigabit of bandwidth. This means that higher bandwidth can be provided with reduced power consumption. This is critical as bandwidth demand and the number of connected users, campuses, enterprises, and devices continue to grow. 50G PON is such a sustainable fiber broadband technology for the future.

Recommendations

Currently, 50G PON solutions are rapidly coming to market. CSPs and IT executives should actively review 50G PON solutions and start lab pilots from 2024. At the same time, carefully evaluate their respective use cases to accommodate a wide range of customer types and applications, covering homes as well as various campus and enterprise scenarios such as smart cities.

PON has been well-proven in supporting multi-user and multi-application access, and it is also a sustainable and easy-to-upgrade technology. Based on PON technology, 50G PON will continue to develop to achieve ubiquitous fiber optic connections.
