XGSPON is actually 40Gbps down, 10Gbps up. The 40Gbps is actually four separate 10Gbps downlinks on different frequencies. Filters are used so that each customer only sees one of those downlinks. Just a little note.
> In reality point to point is not really a benefit in 99.99% of scenarios, residential internet use cannot saturate 10G/10G for long, even with many 'heavy' internet users (most users can't really get more than >1gig internally over WiFi to start with).
This is so true! The whole thing about Netflix is such a canard. A 4K stream from Netflix tops out at 16Mbps. Other streaming services use 25Mbps, or speeds in between. 40Gbps is 1600 individual 4K streams, but XGSPON can only be split to a maximum of 128 customers. I guess if all of those customers have more than 12 televisions going at once…
You’re more likely to see congestion from many customers all hitting a speed test server at once just to see how shiny the numbers are.
- martinald 6mo agoYou're confusing XGS-PON with NG-PON2. NG-PON2 isn't really used anywhere AFIAK, the "real" upgrade path is 50G-PON (50G/50G shared). NG-PON2's tunable lasers are expensive so didn't get traction.
