[Lex Computer & Tech Group/LCTG] Comcast experimenting with hollow core fibre optics

Wed Feb 8 11:12:30 PST 2023

 I think 4.0 sounds very interesting, but for residential use cases, wouldn't the ISP have to be willing to support higher upstream rates through other parts of their network, and not so much the "last mile?"

Good point, Rich. And quite probably there will need to be internal upgrades within Comcast's network facilities. 
To All -- 
So now they want to skip 6G-9G and go straight to 10G? We already have confusion over WiFi5, WiFi6, all the USB 3 name changes, and now this? Wasn't Microsoft skipping Windows 9 bad enough? And folks still calling the 5 GHz home WiFi band "5G wireless"? 
What is our technical language coming to??
One day in Tech we won't be able to say anything other than IngSoc*. And even that word will be subject to a million different interpretations. 
It's like the madness of declaring new "generations" every time there's a new TikTok trend. Pure ad-hype overriding meaningful communication. A generation is currently 27 years in most advanced (post-)industrial societies$.

*IngSoc is a reference to George Orwell's book "1984" in which all spoken language was reduced to that one word.
$ The social science definition of a human generation is the average span in years between the birth of a biological female and the age at which she can be expected to give birth to her first child. This will be much shorter in less advanced countries and regions than in North America and Western Europe. And longer in Japan and Northern Europe than in Turkey and Mexico.

 I thought DOCSIS 3.1 already supported upstream channel bonding upwards of 1 Gbit/s. I recall setting up an office in downtown Boston in 2012 that used DOCSIS 3.0 and the Comcast Business connection was 100/100 Mbit/s symmetrical.

I'm anxiously waiting for DOCSIS 4.0. This is the specific technology that allows those of us on Comcast, and other non-FIOS providers, to finally get more than a measly 25 MB/sec upload speed.

Besides allowing for ultra-fast speeds, one of the best things about 10G technology (another name for 10 gigabit per second internet) is that it won’t require any new connections to be installed, which means you won’t have employees from your ISP digging up your yard.

Now that Comcast has demonstrated how DOCSIS 4.0 modems and 10G can work together to deliver multi-gig internet speeds, the company is starting a nationwide rollout which it says will reach 50 million homes and businesses in the U.S. before the end of 2025.

If you’re a Comcast customer looking for faster internet speeds, the company plans to begin offering 2-gig plans next year.

  They have a 40 km cable near Phily, and it can transmit in both directions simultaneously.  The article says they are getting ready for 10G.
