Nubis Communications announced the launch of its Nitro Linear Redriver, a technology extending the reach of 200Gbps per Lane copper connections to four meters, breaking the copper reach barrier in AI scale-up networks and enabling a tenfold increase in xPU count across multiple racks. The Nubis Nitro family includes the N2004 and N2008 ICs that support four and eight 200Gbps SerDes lanes respectively.

Partnership with Amphenol Communications Solutions (ACS) : Nubis has partnered with ACS to deliver a family of Active Copper Cable products based on the Nitro Linear Redriver by demonstrating 4-meter reach of copper cables from ACS, featuring the Nitro Linear Redriver and industry-leading 200Gbps SerDes at recently held OFC event.
The Nitro Linear Redriver leverages Nubis expertise in linear high-speed analog electronics, originally developed for optical products, to achieve extremely low power, low latency, and extended reach for active copper interconnect solutions. This innovation is crucial for the continued scaling of AI and machine learning systems, which demand radical increases in connectivity between AI accelerators. Compared to alternatives, Nitro based solutions are 10x less power, 100x less latency and 10x less cost than DSP-based solutions, and 2x less power and 2x more reach than legacy analog equalizers, claims Nubis.
Power and Latency: Nitro-based solutions are 10x less power, 100x less latency, and 10x less cost than DSP-based solutions. They also offer 2x less power and 2x more reach than legacy analog equalizers.
Seamless Integration: The Nitro architecture interacts seamlessly with host SerDes, providing high operational simplicity and enabling end-users to maintain their established methodology for deploying passive copper cables while benefiting from the reach advantage of Nitro-based ACC cables.
“Copper cable limitations are one of the biggest issues that data center architects face at 200Gbps per lane SerDes rates,” commented Dylan Patel of SemiAnalysis. “Scaling the reach of copper to over 3 meters using an extremely low power, low latency linear redriver is a game changer for the industry.”
“We expect over 600 million lanes of 200Gbps SerDes to ship per year by 2029. This is by far the fastest growth and largest total number of any speed grade in the history of networking. There is a strong desire to maintain copper for this generation due to its low- power, low latency and high reliability, and Nubis’ Nitro linear redriver will go a long way to maintaining the viability of copper interconnects at 200Gbps per lane,” commented Alan Weckel, 650 Group.
Availability: Chip samples on an EVB and a reference design are available from Nubis now. Active copper cable samples from Amphenol Communications Solutions (ACS) are sampling to lead customers now.
