If you’re searching for evidence of the “green” movement in the tech world, you need look no further than broadband.The broadband industry is quite literally wringing every last dime it can out of the “repurpose and reuse” principle. How you ask? By finding ways to transmit faster and faster speeds over existing phone lines.For about a third of what it costs to re-cable the customer “last mile” with fiber, business and residential customers have been enjoying decent service over copper. But never at anything that approaches the speeds available over fiber optic wiring.To be more specific, copper has topped out at 1.6Gbps until only just recently. The latest buzz has been all about the new IEEE 802.3bz standard which raises speeds to 2.5Gbps for Cat5e cable and 5Gbps for Cat6.An intermediary step to be sure, but a strong one nonetheless.ISPs, businesses, and municipalities are still nervously awaiting the day when customer demand will exceed copper speeds and expensive fiber recabling will need to begin.Thanks to a handful of innovative companies like Sckipio, Assia, KPN, and Alcatel-Lucent, that day of reckoning has been postponed. Super-ultra speeds will soon be available over copper.Let’s take a deeper look at these developments and what they mean for customer experiences heading into the new year.
