CableLabs certifies first DOCSIS 3.1+ device with four OFDM channels

This certification gives cable broadband operators and equipment vendors a clear reference point for DOCSIS 3.1+ hardware with four OFDM channels. It matters because the milestone moves the technology from specification to certified device status, which is the concrete step that matters in deployment planning. For the broader cable ecosystem, it signals continued progression within DOCSIS 3.1+ rather than a new standard entirely. The specific signal to watch next is whether additional DOCSIS 3.1+ devices receive certification with the same four-OFDM-channel configuration.
