The advancements in cable access platforms have made it possible to shift all QAM functionality from the CMTS to the node, and create a fully intelligent solution at the edge of the network. The emerging Remote MACPHY option for DAA pushes all the QAM functionality to the optical node retaining only the aggregation routing and switching functionalities at the headend. As the QAM elements clear out of the headend, the headend platform and the core network becomes open for common core technologies like Metro Ethernet and PON and the optical nodes get the relevant backhaul modules connecting to these networks. This approach has brought unification of the core network for the telcos, where they can use the same optical networks for all flavours of distribution technologies be XGPON, G.FAST, Broadband LTE or DOCSIS 3.1. Casa System’s Remote PHY optical nodes in conjunction with the Axyom vCCAP platform enables the most trusted and advanced delivery platforms for enabling DOCSIS 3.1 networks. Casa Systems provides flexible options of using XPON or 10G Metro Ethernet between Axyom vCCAP and DAA nodes.
