Re: I think they got it right...
said by majortom1029  :Thats what I am saying. The article doesnt state what the max of the service is. It only states what the Ont can handle. By definition of a GPON network, the ONT HAS to be able to handle 2.4 gbits. Existing BPON ONTS must handle 622 mbits.

Lindenhurst, NY | The article states though that the onts have a max of 400 though.
So if this guy is wrong then we cant trust this article then. |

I saw that too (I actually read the article after I posted that). I can guarantee you that on the fiber side of the ONT, they are seeing faster then 400mbits. BPON it self is rated at 622mbits download. Every ONT within a node sees all data, and filters it as appropriately based on the address of the ONT. Traffic destined for that ONT is let through while traffic destined for other machines is dropped. GPON works similar, just at faster rates.
There may be a limitation within the spec though that artificially restricts it down to 400mbits, but that sounds like an awfully round number to be a hard limit for what can be spit out the other end of the ONT.

| 622Mb to ONT; ? Mb to CAT5e for LAN
First - multiple computers / people.
Of course.
Multi-users either gotta' share a single connection's bandwidth.
Or get individual connections / fibers, for full bandwidth.
The ONT may well be sending and receiving at 622Mbps or 2.4Gbps.
But what aggregate speed is given to the user's "LAN" side for the user's Internet access?
I argue for maximum LAN bps to minimize the real time needed to complete data transfers. Aggregate data transfer remains more or less fixed, even at a gazillion bps, when the data is being processed by the human brain. (Again, obviously, not for pure data file downloading / archiving / library building / ...)
Above some Mbps, the brain becomes the slowest network link in the information processing chain.
