The META-DX2+ family of devices are multi-purpose 1.6T Ethernet MAC/PHYs supporting rates from 1 GbE to 800 GbE and 112G PAM4 long reach SerDes. These versatile devices support encryption, port aggregation, Class C/D PTP and hitless 2:1 multiplexing, as well as SerDes crosspoint functionality that enables connectivity to a variety of optical modules, Direct Attach Copper (DAC) cables, packet processors and Ethernet switches. Encryption is a key feature of META-DX2+, providing security via MACsec or IPsec at full line rate. MACsec encrypts Ethernet traffic at the frame level and supports "VLAN tag in the clear", enabling multi-hop routing of encrypted packets. IPsec encrypts IP packets which ensures security across wide-area networks. By providing encryption within META-DX2+, packet processors can offload the task of encryption to META-DX2+, enabling systems to scale up to larger bandwidths while providing end-to-end security. The META-DX2+ family offers variants with 48 SerDes, enabling 1.6T gearbox or hitless 2:1 mux configurations, which is double the capacity of other solutions and cuts the device count in half to enable smaller form factors. The META-DX2+ 32 SerDes variants are pin compatible with the META-DX2L device, enabling META-DX2L designs to easily add encryption, port aggregation, or MAC layer services such as PTP, all within a single Software Development Kit (SDK).
