Credo and EFFECT Photonics to Jointly Develop Coherent Digital Signal Processor ICs for High-Speed Networks

Posted  by GoPhotonics


Credo, an innovator in providing secure, high-speed connectivity solutions, and EFFECT Photonics, a highly vertically integrated, independent optical systems company, announced plans to collaborate on the development of coherent Digital Signal Processor (DSP) merchant ICs, featuring industry-leading power dissipation and performance. The DSPs are expected to deliver the capacity and reach needed to meet the explosive demands for connectivity and bandwidth and enable cost-effective network upgrades over existing physical fiber infrastructure. These merchant silicon offerings have the added benefit of giving customers the flexibility to choose from a variety of transceiver suppliers.

The two companies will work together to develop new coherent DSP products featuring EFFECT Photonics’ coherent DSP technology and Forward Error Correction (FEC), combined with Credo’s high-speed SerDes, I/Os, Analog to Digital Converters (ADCs), and Digital to Analog Converters (DACs). Credo will manufacture and manage the sales and supply channels of the co-developed merchant ICs, and provide complete design services and customer support.

The first products will target 100G ZR and 100G ZR+ applications. The products will work within the popular QSFP28 optical module’s ultralow 5W power envelope and extend network reach well beyond 80km to support advanced application requirements. These products will target new buildouts and the imminent 10G upgrade cycle to 100G for service providers, 5G telecom and fixed-access operators.

Alan Weckel, Founder and Technology Analyst at 650 Group stated, “Merchant solutions will help drive down the cost, and with the installed base of 10G ports in excess of 13M ports, there is a significant installed base that needs to upgrade to 100G to support new applications and traffic patterns, plus potential new market opportunities that coherent DSPs can open up in service provider, cloud, and enterprise edge networks.”

“Coherent technologies are gaining importance as they improve spectral efficiency and increase data throughput. Historically, coherent solutions have been mostly deployed for very long distances due to their high power and high cost,” said Scott Feller, Vice President of Marketing at Credo. “Our first collaboration with EFFECT Photonics will allow us to deliver capabilities that fit into the power envelopes of the most commonly used transceivers at a competitive price, providing our large volume customers with a refined solution that will seamlessly integrate into their existing access and edge infrastructure to address the dramatic bandwidth growth at the network edge.”

“Our field-proven coherent technology and Credo’s high-performance, power-efficient connectivity solutions and semiconductor manufacturing expertise provide a potent combination that we believe could truly revolutionize the network edge and access interconnect market,” said Harald Graber, Chief Commercial Officer at EFFECT Photonics. “The clear market need for this technology presents a truly exciting opportunity for both of our companies.”

The joint solutions will offer numerous benefits, including high performance, small size, excellent energy efficiency and cost-efficient production.

DSP Feature Set/Advantages:

  • Optimized ZR and ZR+ solutions cover 40 to 500km links.
