What Will Broadcom, Huawei, Metanoia & Nokia Bring To Berlin Broadband
- Published: 13 October 2017 13 October 2017
Companies time releases for BBWF, the biggest event of the year. Here are some possibilities for the companies that haven't provided me news yet.
Huawei will brief me at their Hangzhou event this week. For now, I know the 96 port external vectoring boxes are doing well in customer labs and probably ready. Two telcos were impressed.
(Huawei, Calix, and Adtran are very generous with the press, hosting regular events. All three do a good job trying to answer questions when they can. The result is they get far more coverage. I make a point of reaching out to those who tell me less, including writing this as a reminder.)
Metanoia is the third G.fast chipmaker that joins the UNH interops.
10 Gigabits 500 Meters Over Phone Cables?!
- Published: 13 October 2017 13 October 2017
John Cioffi theorizes that 1 Terabit/s over 100m is possible. Several world-class engineers have confirmed the theory appears correct. The same higher-order waveguide modes could deliver 10 Gbps at 500 meters, which is exciting some of the most important companies in the industry. It could drastically reduce the cost of backhauling 5G small cells in the required millions of locations.
Some are using the name Surface Wave over Copper (SWoC) instead of TDSL as the system moves closer to test. Building a test system and proving the real challenges can be met will be expensive. The frequencies involved are at 50 GHz and higher, 200 times higher than the new 212 MHz G.fast.
Who needs fiber? Backhaul By a Dozen Bonded DSLs
- Published: 12 October 2017 12 October 2017
12 bonded lines of 35b VDSL should be able to deliver 2 gig downstream ~400 meters. That's comparable to the most common G.fast backhaul, 2.4 gig GPON. Telcos are confident few will use the high speeds simultaneously so the high over-subscription is realistic. Upstream on the older DSLs is lower, so the upstream will probably be limited.
Kurt Raaflaub says Adtran has trial units at customers. As far as I know, this is the first public description of bonded 35b and I hadn't anticipated this possible use. Deutsche Telekom says 35b will be ready for deployment the second half of 2018.
Broadband Forum BASE Las Vegas October 29
- Published: 06 October 2017 06 October 2017
Reverse power. DTA. Profile 212. Now is the time to start taking advantage of the advanced features, as deployments are approaching one million homes passed. Registration is free at http://bit.ly/2iHz7Dt. See you there. Look for the round fellow with a beard.
David Titus of AT&T will present details from their nationwide G.fast effort.
Tom Starr, Trevor Linney Headline Berlin Oct 24
- Published: 06 October 2017 06 October 2017
Linney is deploying G.fast past ten million British Telecom homes, with more connecting daily. Trevor, speaking for BT, has always been open about the practical results. Starr has led DSL standards and the Forum for 25 years, seen it all and done it all. AT&T is moving aggressively on G.fast from basements around the U.S., so he too will have lessons from the field.
The new Broadband Forum Access Summit is free. Register through the BBWF website at http://bit.ly/2fXnyYg. BBWF registration on site wasn't free last I looked so make sure to register in advance. The Forum is doing a sister event in Las Vegas on Sunday, October 29th. See you at both. Look for the round fellow with a beard.
After Robin Mersh opens the event, Roland Montagne of iDATE, a respected analyst, will review deployments around the world.
Scared By Cable, Bell Canada Chooses Fiber Over G.fast
- Published: 04 October 2017 04 October 2017
Better TV software long kept Bell's DSL ahead of cable, but both Shaw and Rogers are now deploying Comcast's respected X1 software and will likely catch up. CEO Cope hinted to Wall Street he has little choice but to find the necessary capital.
G.fast was considered until very recently but Bell decided to accelerate their fiber home. They have done most of Montreal and are working on Toronto.
