DOCSIS stands for Data Over Cable Service Interface Specification. It is a telecommunications standard used to provide high-speed internet access over cable television systems. DOCSIS allows cable operators to deliver internet services alongside traditional cable TV, enabling faster data transmission and improved network efficiency. The technology works by modulating data signals over the same coaxial cables used for cable TV. This allows for high bandwidth and supports various internet speeds, making it a popular choice for residential and commercial internet services. DOCSIS has evolved through several versions, with each iteration offering enhanced performance and capabilities.
