Deployment of DOCSIS 3.1 solutions promises significant benefits for cable operators and consumers of broadband services. These include not only much higher speeds, but also quality of experience, higher capacity on existing networks and energy efficiency. As the next-generation DOCSIS 3.1 cable standard emerges, Technicolor is among the first worldwide to deliver DOCSIS 3.1 products.

The TC4400 cable modem, which spearheads Technicolor’s DOCSIS 3.1 Connected Home portfolio, is designed to improve quality of service and experience in the home. Featuring two OFDM channels for downstream and upstream, this next-gen data solution is among the first cable modems worldwide to deliver downstream speeds up to 2 Gbps. This enhanced performance enables cable operators to deliver multi-gigabit data services to customers for multiple applications, from IP connectivity to ultra-high speed Internet access and gaming.

Thanks to DOCSIS/EuroDOCSIS 3.0 backwards compatibility, the TC4400 can also be seamlessly deployed on existing infrastructure as a DOCSIS 3.0 modem, providing 32 bonded downstream and 8 bonded upstream channels. What’s more, it offers flexible DOCSIS 3.0/DOCSIS 3.1 upstream and downstream frequency up to 204 MHz split.
