Charter, Vecima notch 8.5Gbps speeds in DOCSIS 4.0 trial

6 Jan 2022

US cable giant Charter Communications has teamed up with Canadian vendor Vecima Networks to successfully demonstrate transmission speeds of greater than 8.5Gbps (downstream) and 6Gbps (upstream) on a HFC cable plant. The demonstration was built using a DOCSIS 4.0 System-on-a-Chip (SoC) for Remote MACPHY Device (RMD) and cable modem solutions, which they say conforms to CableLabs DOCSIS 4.0 specifications.
