ENET48xxZ/99 DPU Flow Processors


ENET48xxZ/99 is a family of flow processors for G.fast solutions, including the ENET4820Z/99 and ENET4840Z/99 flow processors. The family supports Carrier Ethernet switch, OAM/CFM, BBF WT-301, G.999.1 channelized Ethernet, and EFM bonding. ENET48xxZ/99 is implemented on Xilinx’s Zynq family and integrates dual-core ARM Cortex 9 CPUs and programmable logic.
ENET48xxZ/99 flow processors are specially optimized as scale-up solutions for the FTTdp G.fast market, as they are capable of supporting up to 48 G.fast modems, through G.999.1 over 10G interfaces.
