The D4CMTS18 is a DOCSIS 4.0 Cable Modem Termination System engineered to meet the DOCSIS 4.0 FDD/ESD extended-spectrum requirements, supporting downstream and upstream channels up to 1.8 GHz. It accommodates all High-Split (HS) and Ultra-High-Split (UHS) profiles, including UHS684, ensuring maximum flexibility for next-generation broadband deployments. With integrated 10G technology, the D4CMTS18 delivers up to 10 Gbps downstream and 6 Gbps upstream capacity, while remaining fully backward compatible with DOCSIS 3.1, 3.0, and 2.0 devices.
