The AMD 200G/400G High Speed Ethernet (200G/400G HSEC) Subsystem provides the 200G or 400G Ethernet Media Access Control (MAC) with a Physical Coding Sublayer (PCS) including Reed-Solomon Forward Error Correction (RS-FEC) or a standalone 200G or 400GAUI-16 PCS/PMA with RS-FEC.
The 200G/400G Ethernet Subsystem is designed to the IEEE 802.3bs standard. Increased demand from mobile traffic and cloud computing is forcing next generation routers and switches to 400G and beyond.
