– At Last – 1 Gbps over Copper Phone Wires
By Charles Hall
Remember how important the launch of DOCSIS 3.0 has been to the cablecos – it sealed the deal for them having for more than a decade the much more superior broadband technology than copperwire-based telcos, a blow from which those telcos have never recovered. And US telcos are still losing market share to cablecos. The 2 Gbps version of G.fast, which the ITU approved this week may be just as important to copperwire-based telcos worldwide as DOCSIS 3.0 was to cablecos.
The ITU-T Study Group 15 has approved the 2 Gbps version of the G.fast standard, which by using spectrum up to 212 MHz doubles the 1 Gbps of the current G.fast standard. It is truly amazing that 2 Gbps can be achieved over ancient copper phone wires – even though at only relatively short distances. Those “short” distances are long enough that telcos can save billions of dollars in deployment costs – not to mention disruption to consumers – versus installing fiber all the way into the home…
