Verizon buying Frontier

[Juan]

That technology certainly exists but you haven't shown that any fiber ISPs are using it.

PON doesn't strike me as something that could be deployed with multiple routes between the CO and the home.

Just ask AI

Yes, Verizon uses Passive Optical Network (PON) technology for its fiber network:

• NG-PON2
  Verizon uses NG-PON2 for its next-generation fiber upgrades. NG-PON2 has four wavelengths, each operating at 10 Gbps, which can be combined to offer up to 40 Gbps. Verizon chose NG-PON2 because it simplifies the network, eases the upgrade path, and is scalable to at least 100 Gbps.
  
  
• B-PON
  Verizon has been using broadband passive optical network (B-PON) technology since it began construction of its all-fiber network in 2004.
  
  
• FiOS
  FiOS, which stands for Fiber-Optic Services, operates on a passive optical network (PON). FiOS transmits data using light through thin, flexible glass fibers.
  

Verizon's fiber-optic network provides nearly unlimited bandwidth for voice, internet, and high-definition TV services.

My local ISP fiber optic network also uses PON:

Wabash Communications utilizes a PON (Passive Optical Network) technology within their fiber optic network, meaning they use a shared fiber infrastructure to deliver internet service to multiple customers from a single point of distribution.

As does Spectrum:

Spectrum's fiber optic network utilizes a Passive Optical Network (PON) technology, which allows them to deliver internet service to multiple homes from a single fiber optic cable using passive optical splitters, making it a cost-effective way to deploy fiber internet.

I don't think you'd even want to be "home run" to the AP; a cut cable could then cut service. Better it gridded such that with a cut, the service can come from another direction.

Not exactly. The method Verizon has used for video distribution is limited to about the same as cablecos. Equipment limitations (saved $$$). Fiber will carry far more, but they chose to restrict it for $ertain rea$on$…

Frontier has been installing Corning fiber with 144 fibers in it on poles in the area expanding fiber. They did tell me that they do split some of the signals. I am in a rural area. Why would they need 144 fibers? Can they not split them at each home like the cable company does or does each fiber from each home have to feed individually to a node to process the data?

Fiber cannot be "split". It can be multiplexed to put a few customers on a single fiber.

The move to streaming means that everyone gets their own stream and uses their personal bandwidth to get it.

Cable was based on the broadcast model and that doesn't work for streaming.

Well, there is IP Multicasting, but that’s more like DBS running a movie at set times of the day (usually every 30 minutes), and you selecting which starting time works with your schedule. But yes, if I stream "Dune 2" at 15:40 and you decide to also watch "Dune 2” seven minutes later, we're watching unicast traffic, unique to our IP addresses. Double the traffic.

I wonder when my in-Laws' email addresses switch back to @ verizon?

In this age of cloud DVRs, multicasting is not particularly useful. It mostly works for Sports broadcasts in a stadium/arena, but its application elsewhere is very limited.

I'm sorry but Verizon Fios has been " splitting" fibers for years..like almost 20 years


Here is some help to explain

AI Overview

Verizon, like other fiber optic providers, splits fibers by using a technology called "wavelength division multiplexing (WDM)" which allows multiple data streams to be transmitted simultaneously on a single fiber by assigning different wavelengths of light to each data stream, effectively separating them and enabling efficient use of the fiber capacity; this is done through specialized devices called optical multiplexers and demultiplexers at the network nodes.

You're making the horrible assertion that multiplexing is equivalent to splitting. It is not.

Splitting allows you do send the same signal to everyone using only simple distribution amps.

Multiplexing requires a whole lot more technology along with some pretty sophisticated engineering effort.

Using AI to back your ridiculous claims isn't going to improve your underlying arguments.

We really want to quibble over “split” versus “multiplexed?”

Fiber to the takes one frequency and divides it into what are basically time slots that the neighborhood node multiplexes and demultiplexes into one frequency...its an idea similar in concept to subnet masking

When the light leaves the node..it travels thru what is basically a prism that splits the light into different colors..also known as frequencies..each frequency is assigned to a specific customer..on the return trip the prism combines the individual colors ( frequencies) into one color..the node then picks the timeslots off the main frequency..that's a simple explanation

It isn't a quibble, it is a paradigm shift in technology (similar to the shift from analog satellite TV transmission -- or audio -- to digital transmission).

Splitting involves sending a singular signal over multiple paths. Multiplexing involves sending multiple signals over a single path.

One is ideally suited to broadcast while the other cannot practically implement it.

Colloquialisms.

Colloquialisms.

Hardly.

These are technical terms used in the communications industry, not a product of someone trying to use colorful language.

Multiplexing has been around since the 1870s in telegraphy.

Splitting has more than one application but in the context of signal distribution, its meaning is clear.
