Everything You Need to Succeed


The Sckipio DP3000 G.fast DPU Chipset includes the DP3000-D Digital Front-End (DFE) System-On-Chip (SOC) solution and the DP3000-A Analog Front-End chip. Both are used together to implement a Distribution Point Unit (DPU), typically for a Fiber-to-the-Distribution-Point (FTTdp) installation.


The DP3000-D implements four FTU-O transceivers that comply with the ITU G.fast recommendations (G.9700/1) as well as additional functionalities required within the Distribution Point Unit (DPU) and defined within the G.9701 System Reference Model Recommendation.
