What Is DOCSIS 3.0?
With the DOCSIS 3.0 specification, cable Internet providers can take advantage of the extra capacity provided by channel-bonding technology in order to offer ultra-fast broadband services. Channel bonding allows parallel data pipes to act as a single broadband conduit. With each channel capable of providing around 40 Mbps of data, the Motorola SURFboard SB6121's four downstream channels can provide a theoretical maximum of 160 Mbps of throughput.
Currently, cable providers max out at around 50 Mbps of downstream data throughput, but DOCSIS 3.0 will enable cable Internet providers to continue to improve the speed of their networks.
