Meanwhile on AT&T FTTH, the highest speed is 18/1.5Mbps
Subj. I have a fibre strand in my bedroom closet in Midtown San Jose, CA, 95126, connected to an AT&T-branded Alcatel HONT-C, running at 622/155Mbps, the capacity that is shared with at most 32 users (that's how BPON works), yet the highest upload speed that AT&T seems to provide to their U-verse FTTH customers is 1.5Mbps, some 666x slower than 1Gbps. Even in the worst case scenario, they leave some two-thirds of the upload capacity sit entirely unused! (32 (users at most) × 1.5 (Mbps per user) is 48 Mbps, then 155 Mbps − 48Mbps is lots of unused and underprovisioned capacity! More than 100Mbps absolutely, and more than two-thirds relatively!)
Yes, the 24/3 package is only provided to FTTN (single pair VDSL2) customers, both FTTH (fibre-to-the-home) and FTTN-BP (bonded VDSL2) are artificially limited to 18/1.5, even though obviously both FTTH and FTTN-BP are capable of speeds much higher than FTTN!
»AT&T U-verse FTTP speeds, why do they limit fibre to 18/1.5?
»yet no new CPE needed for FTTU upgrades, yet none are here
Anyhow. High respect to Utopia and Utah residents and voters, and congrats with 1Gbps!
