If you have upgraded your broadband to the ultimate 10Gbps speed grade and now wonder, “What’s next?” here’s some news that will pique your interest: 50Gbps broadband is coming.
Indeed, Broadcom today announces its BCM68850 system-on-chip (SoC) as a complete 50G-PON solution for the home.
Broadcom BCM68850: 50Gbps broadband meets Edge AI, and Wi-Fi 8
Broadcom says the BCM68850 is the industry’s first 50G-PON Customer Premises Equipment (CPE ) gateway SoC to feature an integrated Neural Processing Unit (NPU) and native Wi-Fi 8 compatibility.
As a result, here is what consumers can expect from it:
- High-Performance Application Engine: A dedicated CPU for third-party and operator applications leveraging industry-available middleware.
- Integrated Neural Engine: A dedicated NPU that accelerates Edge AI inference, reducing cloud latency and enhancing data privacy by keeping sensitive information on premises.
- Symmetric 50G Performance: Delivers full 50G throughput to meet the insatiable appetite for reliable, multi-gigabit bandwidth.
- Wi-Fi 8 Ready: Native compatibility with Wi-Fi 8 standards to ensure the highest reliability and real-world consistency at the broadband edge.
- Intelligent Self-Healing: Enables operators to implement real-time anomaly
detection and predictive bandwidth optimization, reducing operating expense or operational expenditure (OpEx) and improving average revenue per user (ARPU). - Advanced Security: Incorporates enhanced security algorithms, including Post Quantum Cryptography (PQC).
In other words, apart from delivering the latest broadband speed, a BCM68850-based gateway (or router) also comes with integrated Edge AI and the upcoming Wi-Fi 8 standard—it has everything a home would ever need in terms of bandwidth and high-end features.
An exciting upcoming 50G landscape
It’s important to note that prior to this, Broadcom had already announced two other chips relating to the 50G-PON ecosystem in late 2024: the BCM55050 for standalone ONTs and the BCM68660 Optical Line Terminal (OLT) for Internet providers.
Today’s BCM68850 chip is the third to complete the chip maker’s end-to-end 50G offering, bringing 50 Gbps Internet that much closer to a reality.
If you’re thinking that you don’t need 50Gbps broadband, you’re not wrong, given 10Gbps is more than fast enough for any application, and most devices are limited by their Gigabit port or Gig+ Wi-Fi’s real-world speed.
Tip
Gig+, or Gig Plus, denotes a speed grade between 1Gbps and 2Gbps. So, it’s 1.5Gbps, give or take a couple of hundred megabits per second, and it’s not speedy enough to qualify as Multi-Gig Ethernet or multi-Gigabit. Intel coined the term to describe its Wi-Fi 6E client chips, the AX210 and AX211, in terms of their real-world speeds.
Gig+ primarily applies to sustained Wi-Fi 6 or Wi-Fi 7 speeds via a 2×2 at 160MHz connection, or to broadband internet speeds.
However, the higher bandwdith means more devices within a network can connect at their top speed. Specifically, a 50 Gbps gateway technically allows up to 50 devices to connect at full Gigabit each simultaneously.
What’s more significant, though, is the fact that the new bandwidth will improve the quality of Internet traffic in ways we haven’t been aware of. No matter how small the amount of data that needs to be transmitted, the process takes time. And sometimes the quality of the experience depends on the ability to transmit data instantaneously.
Per Broadcom’s phrasing, as home networks evolve in the age of AI, with highly active applications, Internet traffic will generally consist of increasingly large, instantaneous micro-bursts of data—sudden, rapid “payloads” that swamp network links or devices in milliseconds. Broadcom says a Fiber-optic gateway based on its new 50G-PON BCM68850 SoC can process and transmit these high-density payloads in a fraction of a millisecond, instantly freeing the channel for the next payload.
For example, 2 MB of data requires over 13,000 microseconds to transmit over G-PON, or 1,600 microseconds via a 10G-PON. With 50G-PON, only 320 microseconds are needed.
In other words, this ultra-fast “burst and release” capability guarantees near-zero-jitter performance essential for latency-critical applications, forming the infrastructure for the near future when AI-related real-world applications and true interaction become commonplace.
To recap, with existing applications, more bandwidth and faster connection speeds never hurt. 50G-PON is also capable of reducing latency to a new level and opening up new types of applications most consumers haven’t heard of before.
Availability
Broadcom says it’s currently sampling the BCM68850 CPE and BCM55050 ONT chips to its early access customers and partners. It’s estimated that 50Gbps-capable ONTs and gateways will become available to consumers by late 2027 or early 2028, which is also when the first Wi-Fi 8 hardware is expected to materialize.
