At UBBF 2023, Huawei‘s Richard Jin’s keynote speech made waves as he proposed a three-phase network construction concept. Network development, he mooted, is driven by three elements: video demanding a 100Mbps network, experience needing a 100Gbps network, and intelligence mandating a 10Gbps network. Following this, Huawei presented its three-phase all-optical target network architecture that aims to enable F5.5G and takes significant steps towards an intelligent, interconnected world.

Jin proposed three distinct stages of implementation in his roughly chronological plan. He started by discussing the initial phase focused on video-driven broadband, magnifying the need for all-optical coverage for 100Mbps home broadband. With the constant augmentation of video resolution, there’s a necessity to strengthen bandwidth, upgrading it from 10 Mbps to 100 Mbps for a superior video interaction experience. This phase strives to replace the traditional copper lines with FTTH all-optical networks for better connectivity. Operators should prioritize deploying OTN to metro aggregation layers, effectively supporting a non-blocking bandwidth, thereby ensuring zero video lagging.

Shifting gears to the second stage, Jin shed light on the increasing demand for all-optical connections that extend 1Gbps to each room. With a rising surge for diversified digital applications, network users now require a more premium, immersive network experience. Providers should upgrade 10G PON to deliver the best of gigabit services, introducing fibre to every room (FTTR) to ensure complete network coverage while minimizing latency and roaming.

The third and last phase delves into intelligence and aims towards all-optical computing for 10Gbps. AI plays a crucial role here, accelerating content manufacturing and promoting the transformation of industries to an intelligent platform. This stage covers the need for an all-optical home bus that supports IoT device connectivity and integrates connection, sensing, computing, and storage capabilities for 10Gbps throughout different spaces in a house.

Under the larger umbrella of creating a three-phase all-optical target network, Huawei’s approach conservatively guarantees a smooth transition and, eventually, an upgrade from F5G to F5.5G. This phased move aims to change the content at 100Mbps, provide a distinct broadband experience with 1Gbps, and revolutionize society with a sweeping 10Gbps. Data-friendly and intelligent, the F5.5G-oriented three-phase all-optical target network architecture by Huawei can certainly be a game-changer in the telecommunications industry.
