Cox Communications has been testing a unique Block Division Multiplexing (BDM) technology from Xtend Networks to significantly increase the capacity of existing coaxial plants. Xtend’s solution provides an additional 2 GHz of spectrum on the coaxial plant while remaining compliant with standardized DOCSIS equipment, such as cable modem termination systems (CMTS) and cable modems. BDM then builds on that foundation to help cable operators target individual or regional customers with extra symmetrical high-speed bandwidth that does not detract from residential services. Cox plans to use Xtend’s solution to deliver dedicated bandwidth with QoS to commercial customers.
