Summary Bullets:

• G.fast, ratified a week ago by the ITU, can deliver up to 1 Gbps of aggregate throughput to end users over the existing telco copper plant. With testing and some limited commercial deployments planned for 2015, is the hype about G.fast deserved?

• Will developing cable access technologies such as DOCSIS 3.1 and CCAP provide cable operators with effective countermeasures to G.fast and other telco copper-focused enhancement technologies?

One week ago today, on December 5th, the ITU ratified the G.fast standard. For many industry insiders, this was no surprise. In fact, it was simply the formal approval of G.fast specification G.9701, per the ITU’s schedule. However, the media buzz generated by the ITU’s G.fast approval has seemed disproportionately higher than expected. So, what gives? Is December a slow news month? Yes. Are there not more important things to write about in terms of fixed broadband? Actually, no. Finally, does G.fast deserve all of this attention? Well, yes! Read more of this post
