A reader wondered about my 35b story writing, "35b to my knowledge is already in market." I know Fastweb in Italy is already selling to consumers at "Up to 200 megabits" but without vectoring they will often be much lower. On the other hand, Deutsche Telecom, the largest expected customer, says it won't be ready until 2019. I believe what's going on is that Broadcom is selling 35b chips but the vectoring isn't ready for large deployments, but the primary sources aren't providing answers.
The reader, wanting to be confident, asked what were my sources for the story Deutsche Telecom: 35b Supervectoring Delayed to 2019? That's always a fair question.
I've been reporting 35b since 2015, but this story was inspired by an article by Achim Sawall Super Vectoring kommt bei Telekom erst im Jahr 2019. (250 MBPS:Super Vectoring will not be available at Telekom until 2019) (All translations by Google.)
"Super Vectoring with data transfer rates of up to 250 MBit / s will only be available at Deutsche Telekom in 2019.
Telekom CEO Tim Höttges said in the conference call on the presentation of the figures for the third quarter of 2017: "Up to 250 Mbps will be offered by 2019 ." Earlier, the telecom announced that it would offer the technology in the second half of 2018."
The official statement from DT did say 2018, so I checked with Sawall, a respected reporter. He had read the same, but confirmed to me that DT had updated the timing at a later press briefing.
That the vectoring necessary for wide deployment of 35b wasn't ready was confirmed to me last fall by Huawei & Adtran, who both were hopeful of results early in 2018. It's quite possible that DT, always conservative, is allowing more time for testing and employee training than others will. I wouldn't be surprised if some other telco deploys earlier.
All of us are waiting for detailed results from the field.
