Verizon buying Frontier

[harshness]

With the advent of symmetrical broadband speeds, I don't imagine they're using splitters like they used to. Back in the day, the TV broadcasts were multicast and today they are largely unicast.

Remember narrowcasting?

I removed a post here where I claimed that my Metronet (marketed as T-Mobile Fiber) system used Wave Division Multiplexing to provide for multiple homes on a fiber. That was based on a mistaken idea that I had formed based on previous experiences in data networking before I retired. In reality the distribution is based on XGS‑PON technology, which takes a 10Gbps fiber signal and splits it optically either 1:32 or 1:64. Everybody receives the same packets. Downstream packets are addressed individually to the customer ONT, and the head end manages the fairness of the packet distribution so that no one customer can cause a serious impact to anyone else, as long as the provider doesn't oversubscribe. The upstream data sharing is managed by assigning each ONT a time slot to send packets. The bottom line is that when testing from my router I see 2Gbps up and down. I did not get that result when first hooked up, but it was resolved within 24 hours, after i complained.

We all know the provider over subscribes...no such thing as garunteed bandwidth

Since there is competition between Optimum and T-Mobile Fiber (MetroNet) here, and most customers are clueless as to the technology behind their ISP connection, I have stopped recommending T-Mobile to my neighbors in order to cut down on the oversubscription, unless they ask for my opinion.

Seems like a pretty pointless statement given that you don't have FTTH available to you.

Dozens of millions of satisfied DOCSIS users can't all be wrong.

DOCSIS is fine for download. It can't deliver the upload speed of fiber.

It doesn't matter how wonderful fiber can be if all you have access to is cable.

I'm currently getting 130Mbps up on Xfinity's 150Mbps plan, and that's more than enough for most uses that are in accordance with most ISP's AUP.

While fiber can go much higher, Charter is in the midst of implementing their high split upgrades, allowing for 1 Gbps upload over DOCSIS. They are even offering 2 Gbps Down/1 Gbps Up in some locations. Considering the vast majority of customers are limited by their own gigabit networking hardware, gigabit upload, while not the fastest, is nothing to overlook either.
