Powering Scale Up and Scale Out with 224G SerDes for UALink and Ultra Ethernet
At the recent ECOC 2025 conference in Copenhagen, Cadence showcased its key role in enabling the future of AI infrastructure with live silicon demonstrations of several essential IP technologies for emerging 800G and 1.6T networks. Powered by Cadence's 224G SerDes IP, Cadence's Ultra Accelerator Link (UALink 1.0) scale-up and Ultra Ethernet scale-out networking solutions deliver the performance, flexibility, and interoperability needed for next-generation AI factories and hyperscale data centers.
O-RAN Fronthaul Security using MACsec
With 5G being deployed for time-sensitive applications, security is becoming an important consideration. At the same time, Open Radio Access Networks (RAN) are gaining more interest from mobile carriers and governments. Yet, Open RAN networks have serious security challenges, especially in the RAN fronthaul where there are strict timing requirements. This paper proposes MACsec as an efficient data link layer security solution that can assist in meeting these challenges.
Seize the Ethernet TSN Opportunity
The following sections will take a look at the major Ethernet performance issues and how the extensions address those shortcomings. This will be followed by an overview of the applications of TSN for 5G, industrial automation, automotive invehicle communications and avionics. The paper will conclude with a description of Ethernet TSN solutions offered by Comcores.
Part 2: Opening the 5G Radio Interface
Carriers are now deploying 5G across the globe driven by the need to keep up with relentless mobile data growth. 5G New Radio (NR) operates at higher frequencies to increase bandwidth, but at the expense of range. There will therefore be a need for a much larger number of 5G RUs to provide the same coverage. The availability of cost-effective, reliable and open 5G radio units is therefore critical.
Accelerating 5G virtual RAN deployment
This whitepaper provides an overview of the O-RAN Alliance and the value provided by O-RAN to the carrier industry along with a brief introduction to Comcores, our O-RAN solutions and our role in the O-RAN eco-system.
