Analysts believe that DOCSIS 3.1 modems will be gaining significant traction over the next couple of years. The modem models, which are receiving certification from CableLabs in growing numbers, are expected to reach 9 million cable subscribers by 2017, or 1% of total cable broadband service subscribers worldwide. DOCSIS 3.1 modems can compete with fiber-based solutions by offering downstream speeds of up to 10 Gbps over standard copper wire.
Both Comcast and Liberty Global are planning to be aggressive with their DOCSIS 3.1 deployment schedules. Comcast has already announced that its DOCSIS 3.1 strategy includes delivering the new modems to its entire broadband subscription base by the end of 2018, a number that exceeds 20 million households. Meanwhile, Time Warner Cable expects to extend the life of its DOCSIS 3.0 installations, and during a recent earnings report, expressed satisfaction that nearly two-thirds of its residential home customers have DOCSIS 3.0 modems.
