Data Over Cable (DOCSIS) is a telecommunications standard used to transmit high-speed internet data over existing cable television networks. It allows internet service providers to deliver broadband services to homes and businesses using the same infrastructure that carries cable TV signals. This technology enables faster internet speeds and improved connectivity. DOCSIS works by modulating data signals and sending them through the cable modem to the cable network. The latest versions of DOCSIS, such as DOCSIS 3.1, support gigabit speeds and enhance network efficiency. This makes it a popular choice for many internet service providers looking to meet growing consumer demand for high-speed internet access.
