Xilinx Demos 112G PAM4 Electrical Signaling FPGA Technology for Optical Networks

12 March 2018

Xilinx Inc. will showcase its latest optical networking field programmable gate arrays (FPGAs) at the 2018 Optical Fiber Communication Conference and Exposition (OFC) being held this week in San Diego, California.

The company will show its 112G PAM4 electrical signaling technology for optical networks as well in addition to its 16 nm Virtex UltraScale+ portfolio with a 58G PAM4 transceiver. Xilinx sees the transition to 58G and 112G transceivers as an important step to deliver 400G and 800G+ data rates using the existing footprint.

The new 58G PAM4 FPGA is built on the Xilinx’s transceiver architecture that enables designers to double the bandwidth capabilities of existing systems through programmable logic with 58G PAM4 transceivers. The devices are targeted at cloud computing, 5G networking, core networks and network functions virtualization (NFV) applications. The new transceiver technology will enable vendors to scale 50G, 100G and 400G ports and terabit interfaces in compact and less complex system designs.
