Marvell samples Nova 1.6 Tbps PAM4 electro-optics platform

Marvell announced sampling of its Marvell Nova 1.6 Tbps PAM4 electro-optics platform.

Marvell's Nova is powered by a 200 Gbps/lambda optical DSP capable of enabling 1.6 Tbps pluggable modules in the OSFP-XD form factor.  

Key features of the Nova electro-optics platform include:
  • 200 Gbps per channel line side transmitter interface supporting a wide range of high-speed lasers
  • 200 Gbps per channel line-side receiver with companion Marvell 112-Gbaud TIAs, providing best-in-class linearity and low noise 
  • Integrated laser drivers, optimizing power dissipation
  • Latency-optimized FEC for 200 Gbps traffic

“As new AI and ML compute architectures drive increased bandwidth requirements, high-speed optics will continue to form the backbone of cloud data centers,” said Dr. Loi Nguyen, executive vice president, Optical and Copper Connectivity Group at Marvell. “Our next-generation electro-optics platform scales data interconnect transfer speeds to meet the needs of the most demanding AI workloads. We are thrilled to lead another breakthrough in electro-optics speed transition and expand Marvell’s market-leading PAM4 DSP portfolio with the availability of Nova.”

Marvell previews 51.2 Tbps Teralynx switch

Marvell Technology announced its Teralynx 10 Ultra-Low Latency Programmable 51.2 Tbps switch chip. It can be paired with the newly-annouced Nova PAM4 1.6 Tbps electro-optics platform for handling high-bandwidth workloads in artificial intelligence (AI)/machine learning (ML) and cloud data center networks. The new platform quadruples the bandwidth of Marvell's widely-deployed 12.8 Tbps networking solutions.

Key features of Teralynx 10 include:

  • Up to 512 SerDes lanes supporting 25 Gbps, 50 Gbps and 100 Gbps I/O speeds to support a wide range of switch systems and connectivity
  • Congestion-aware routing to minimize network bottlenecks and congestion
  • Permutable flex-forwarding to enable operators to program new packet forwarding protocols as networks evolve
  • Teralynx Flashlight telemetry with support for P4 in-band network telemetry

Marvell notes that its cloud-optimized Teralynx 10 and Nova networking platform ensures interoperability between switch and optics, thereby reducing the burden of validation and interoperability testing for customers and accelerating the deployment of these next-generation technologies. 

“Data center operators are challenged to meet the networking demands that applications such as artificial intelligence and machine learning are driving in the cloud,” said Nariman Yousefi, executive vice president, Automotive, Coherent DSP and Switch Group at Marvell. “To address this demand, leading operators are planning to upgrade directly from 12.8 Tbps to 51.2 Tbps. Utilizing the industry’s lowest latency programmable switch, Teralynx 10, with the industry’s first 1.6 Tbps optical platform, Nova, offers data center operators a cloud-optimized platform to scale and address the growing demands of AI/ML applications.”

Adtran carries 800G wavelength over 2,220km

Adtran completed a field trial of 800 Gbit/s single-carrier transport, achieving error-free transmission over a record distance of 2,220km in NYSERNet’s production network. 

The test route passed through 14 route-and-select flexgrid ROADMs comprising a total of 28 wavelength-selective switches. 

The trial used Adtran’s FSP 3000 open line system (OLS), which provided the necessary flexibility to configure the wider required bandwidth and perform testing. It also utilized Acacia’s CIM 8 transceiver technology, which increases baud rates up to 140Gbd to generate 800Gbit/s signals. 

“We’ve taken single-carrier 800Gbit/s data transmission further than ever before. And we’ve achieved it not in a lab but in a real-world network also carrying live traffic. What’s more, we succeeded without any optimization to the line system, maintaining the same amplifier settings used before the field trial. We’ve demonstrated that the highest capacity and reach can now be accomplished even over deployed fiber comprising a mix of standard G.652 and G.655 and including multiple network nodes and flexgrid ROADMs,” said Sorin Tibuleac, director of system architecture at Optical Networks, Adtran.
