coax4life writes: While Verizon and AT&T lay fiber, cable companies are looking at a huge bandwidth crunch according to a new report. Increased demand for high-def programming on the TV side and faster download speeds on the ISP side of the business will leave cable companies in a rough spot — after spending over $100 billion in the last decade on infrastructure improvements. Jumping on the fiber bandwagon may help. 'Upgrading to a fiber infrastructure is a much more expensive proposition, and one more likely to occur in areas where the cable companies are facing more competition. It can happen, though — several years ago, Comcast's predecessor on the northwest side of Chicago laid fiber on top of its existing coaxial installation. The payoff is good for both cable companies and users, as it can result in more programming choices and faster Internet access.' Moving to switched digital video solutions will also help.
