The megatrends of cloud computing, Big Data, IoT, Social and Web2.0 continue to accelerate and drive the insatiable need for unlimited bandwidth. There is a clear need to increase the speed of the interconnect pipes, within data centers over short reach data center optical connectivity and to deliver low cost, high-speed 50/100/200/400G interconnects supported by smaller form factor modules. PAM4 modulation has now been recognized as the modulation scheme that will take the industry over the next wave of Ethernet deployments for optical interconnects by doubling the bits per symbol at the same baud rate. The Inphi PAM4 DSPs deliver best-in-class performance, while providing new levels of power efficiency and speed required for hyper-scale data centers.
Polaris™ is the industry’s first 16nm 28GBaud CMOS PAM4 platform solution, that includes integrated driver options for EML and VCSEL lasers to cover a broad range of optical interconnects from 50G to 400G. The platform also supports a family of discrete EML and VCSEL drivers and linear TIAs and and is available in one of the following options:
• 200G(4λ)/400G(8λ))VCSEL OSFP/QSFP-DD
• 400G 8λ PAM (EML) OSFP/QSFP-DD
Porrima™ is the world’s first 16nm 400Gbps PAM4 platform, the first complete 56GBaud platform solution for wired network infrastructure including hyperscale cloud data center, service provider and enterprise networks. The platform solutions includes field-proven PAM4 DSP technology, Linear TIA and Drivers for up to 400G client optical modules and is available in one of the following options:
• 400G PAM 4λ(EML) OSFP/QSFP-DD – FR4
• 400G 4λ PAM (DML) OSFP/QSFP-DD – DR4
100G 1λ PAM (DML) QSFP28 – DR1
