Broadband, Cabling, Comcast
Comcast will be rolling out a DOCSIS 3.0 trial in Minnesota, with the top download speed 50 Mbps (5 Mbps upload). The service will be the first deployment of the faster cable modem standard, and the interest level will be high since DOCSIS 3.0 is the only architecture that can rival FTTH in performance. However, it’s interesting that Comcast is deploying in Qwest’s territory; the operator has only DSL in contrast to its eastern rival Verizon, whose FiOS can also offer 50 Mbps in some areas. We note that DOCSIS 3.0 is still a shared-media technology with less capacity available per user than FTTH can support, and the upload speed for cable is much lower than for FiOS (which now offers 20/20 symmetrical and 30/20 asymmetrical in some areas).
