Broadcom has shipped more than one million units of its channel bonding cable modem silicon for downstream channel bonding cable modems. Compatible with existing DOCSIS 2.0 and next generation cable modem termination system (CMTS) equipment, Broadcom cable modem silicon delivers downstream data rates of up to 150 Mbps and enables multiple service operators (MSOs) to deploy downstream channel bonding functionality immediately.
Broadcom said channel bonding is often cited as the most significant feature of next generation DOCSIS 3.0 products. Whereas DOCSIS2.0 products are limited to single downstream and upstream channels, next generation products will use channel bonding to combine the bandwidth of several DOCSIS channels to significantly increase data rates.
