DOCSIS, or Data Over Cable Service Interface Specification, is a standard for high-speed internet transmission over coaxial cables.

DOCSIS 4.0, the latest version, offers significantly improved speeds (up to 10 Gbps downstream and 6 Gbps upstream), enhanced security, and full-duplex communication. It achieves this through technologies like channel bonding, OFDM, and ESD, leveraging existing HFC infrastructure.

While GPON offers symmetrical speeds and greater scalability, it requires more costly infrastructure upgrades. DOCSIS 4.0's backward compatibility and scalability make it a key technology for meeting the demands of modern broadband internet services.
