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.
