What is a DOCSIS Remote?

A DOCSIS Remote, also known as a Remote PHY Device (RPD), is a network component used in cable broadband systems to extend DOCSIS (Data Over Cable Service Interface Specification) services closer to the customer's location. It separates the physical (PHY) layer from the cable modem termination system (CMTS) and places it in a remote node, which helps improve bandwidth, reduce latency, and simplify the network architecture. DOCSIS Remotes are commonly used in distributed access architectures to support higher internet speeds and more reliable service for cable broadband providers.
