50G PON
Analysis: Broadcom’s end-to-end 50G PON Edge AI portfolio with WiFi 8 support
Broadcom has announced the BCM68850, a 50G ITU-T PON home gateway system-on-chip (SoC) that integrates a neural processing unit (NPU) and provides native support for emerging Wi-Fi 8 (IEEE 802.11bn) capabilities. The device extends the evolution of broadband access silicon toward higher-capacity passive optical network (PON) standards while maintaining alignment with next-generation in-home wireless technologies. Broadcom is currently sampling the BCM68850 and BCM55050 to its early access customers and partners. Please contact your local Broadcom sales representative for samples and pricing.
The integration of NPU functionality within the gateway reflects an architectural trend toward distributing compute resources closer to the network edge. This enables localized processing of AI-driven workloads within customer premises equipment (CPE), which can reduce upstream bandwidth demand and improve responsiveness for latency-sensitive applications.
Migration to 50G PON, as defined within ongoing ITU-T standardization efforts (e.g., Higher Speed PON), provides increased access capacity and improved latency characteristics relative to earlier generations such as XGS-PON. These enhancements support more deterministic service delivery, particularly in environments where traffic patterns are becoming increasingly burst-oriented and driven by compute-intensive applications.

In residential networks, traffic is expected to increasingly consist of short-duration, high-throughput bursts associated with edge processing, real-time analytics, and interactive services. A 50G PON gateway can accommodate these patterns by transmitting high-density payloads over sub-millisecond intervals, after which shared channel resources are rapidly released for other users. This behavior contributes to improved utilization efficiency on shared fiber infrastructure.
Low-latency and low-jitter performance are important for emerging application classes, including distributed AI inference, synchronized edge workloads, and multi-stream ultra-high-definition media. These requirements extend across both the access network and the in-home wireless domain, reinforcing the need for coordinated evolution of PON and Wi-Fi technologies.
From a deployment perspective, introduction of 50G-capable CPE provides operators with additional capacity headroom and supports alignment with future service requirements. Coupled with advancements in IEEE 802.11bn, this approach enables continued scaling of residential broadband performance while maintaining consistency across access and local network segments.

HKT is first to deploy 50G PON technology in Hong Kong
HKT [1.] has become the first telecommunication service provider in Hong Kong to adopt the latest 50G PON technology, as the telco prepares to ramp up the delivery of applications that require ultra-high-speed broadband Internet connections for both home and commercial customers.
Note 1. HKT Limited is a company incorporated in the Cayman Islands with limited liability.
50G fiber based broadband offers a significant step up in speed, with a specification download speed of up to 50Gbps. Paired with the latest Wi-Fi 7 technology, the remarkable increase in bandwidth supports smooth simultaneous multi-device connectivity of all kinds for users both at home and in a commercial setting. Latency also improves by a substantial 27% on average compared to that of a 10G fiber network. [The above latency is only applicable to designated servers. Network latency in other areas will vary depending on the operational load of individual servers as well as network traffic.]
Bruce Lam, CEO, Consumer, HKT, said, “NETVIGATOR has always been at the forefront of the market. We are delighted to become the first telecommunication service provider in Hong Kong to adopt 50G PON technology.

Ooredoo Qatar is first operator in the world to deploy 50G PON
Ooredoo Qatar announced that it has become the first operator in the world to deploy 50G PON (Passive Optical Network) connectivity, the 50 Gbps-capable fiber-based access connection for consumers. According to Ooredoo, the 50G PON technology, which has been adopted as an ITU standard, delivers fiber-based access connections with speeds of up to 50 Gbps on a single connection.
The 50G-PON system capitalizes on fundamental advances in the optical transceiver components working in conjunction with enhanced error correction and coding. It also introduces key innovations in activation procedures, contention-based operation, and expanded cryptographic features. With these improved capabilities, the 50G-PON system is ready to meet the new, and demanding, requirements of emerging services.
This new technology enables consumers to use high-bandwidth latency-sensitive applications such as 8k-interactive video applications, online collaboration and coordination solutions, 3D cloud design, high-graphic/high-quality AI applications, etc.
Dell’Oro Group believes total 50G-PON equipment revenue will increase from less than $3M in 2023 to $1.5B in 2027. Much more significant growth is expected after 2027, as operators begin to evolve their 10Gbps PON networks to next-generation technologies.
Sheikh Ali Bin Jabor Al Thani, Chief Executive Officer, Ooredoo Qatar, said: “We’re proud to be the first operator globally capable of deploying such powerful technology, which aligns perfectly with our overarching aim of upgrading our customers’ worlds. We have long had a strategic commitment to partnering with global leaders in technology and innovation, enabling us to leverage both our expertise and experience and our partners’ capabilities. This latest launch is an excellent example of the benefits we, and our customers, enjoy as a result of such partnerships. We look forward to further enhancing our offering as technology develops ever further in the years to come.”
Ooredoo’s 50G PON technology can meet the bandwidth requirements of both consumers and enterprises. Initial deployment will be for B2B customers and areas that require high-speed connectivity, with roll-out to consumers – for 8k content and AR/VR gaming, as an example – to follow.
ITU-T standards for 50G PON:
In April 2021, the ITU-T reached a major mile-stone, consenting the first three Recommendations defining a 50G PON system:
- General Requirements (G.9804.1): The legacy features linked to deployed fiber infra-structure are complemented by support for new services requiring high capacity, efficiency, low latency, and security. Coexistence with, and migration from, the installed PON systems are essential.
- Common Transmission Convergence Layer (ComTC) specification (G.9804.2): This is defined in a line rate agnostic way and thus applicable to future single-wavelength time-division multiplexing (TDM) and multi-wavelength time-and-wavelength-divi-sion multiplexing (TWDM) PON systems.
- The single-wavelength 50G-PON PMD (G.9804.3) specification is the first in the HS-PON PMD family.
