I have been trying to get Verizon to fix a problem with poor upload speeds for months now. In my research in trying to find the solution on my end, I came across this here on DSLreports:
What is BPON or GPON?
BPON: Broadband Passive Optical Network
GPON: Gigabit Passive Optical Network
FiOS networks are built upon Passive Optical Networks.
BPON conforms to the ITU-T G983.1 specification which is capable of 622 Mbps download and 155 Mbps upload. Each BPON fiber is split using an optical splitter to serve 16 or 32 users.
GPON conforms to the ITU-T G984.1 specification. Verizon's GPON implementation uses Gig-E instead of ATM that was used with BPON. A 2.4 Gbps download speed coupled with a 1.2 Gbps upload speed. Each GPON fiber is split to serve 16 or typically 32 users. Verizon's next phase of GPON will support 64 users per fiber.
Verizon is building new networks with GPON technology, while existing BPON systems will only be upgraded when capacity limits are reached.

The issue is pretty much fixed. I do notice little random slow downs here and there but after upgrading and having them install a GPON unit there has definitely been a vast improvement.
Just to be clear, I am on the 150/65 plan now and may downgrade soon as this is definitely more bandwidth than we need at my residence but they had to switch me to GPON and onto a new splitter in the neighborhood so it pointed to an oversaturation issue on the previous splitter and BPON.
If the issue comes back after I downgrade to the 75/35 I was on previously I'll update here.
I have figured out what months and somewhere around 8 technician visits to my house, and their entire NT department, couldn't figure out, or wouldn't tell me.
My problem is that the splitter that provides me with service is over-saturated by having 31 other customers use so much upload bandwidth that I have constant disconnects while trying to stream to any streaming service using any software or hardware, or computer, available to me.
So, the truth about FiOS is that, contrary to what I believed and what a couple of the technicians that came out told me, FiOS works just like the other cable technologies, and the service they sell you is only good to the splitter, not to your house. There is more bandwidth provisioned to the splitter than what they charge you for (155Mbps upload whereas I pay for 35Mbps upload), but once it is saturated the connection you get will be something less. In my case, so much less that it causes disconnects and timed out speed tests using Verizon's own speed test site.
My guess is that the only reason FiOS has ever been more reliable is that there is more bandwidth available through BPON splitters than whatever the other cable companies use. However, once that bandwidth is saturated, you will have the same problems with FiOS as any other solution provided by companies like Time-Warner or Comcast.
I don't know what Verizon's corporate policy is, but no one at Verizon I have talked to - support staff on the phone or on the Verizon support forums here, NT technicians, or technicians sent to my house - has ever been inclined to tell me any of this. In fact, I have been told that FiOS didn't work the way it actually does.
Having been someone that has sung praises about FiOS for years, I think it is now my duty to correct the misinformation I have helped spread. I hope the people I have inadvertently lied to will understand and forgive me.
