Deutsche Telekom is finally realizing that 50 megabits isn't enough. VP Franz Seiser is blunt. "We must change radically, become disruptive and, above all, throw away things," he proclaims at BBWF. After years of DT insisting 50 megabits is plenty, we now hear "it is about Gigabit products" from his colleague Robert Soukup.
A lucky building in Frankfurt will receive 500+ megabit service as ultra-conservative Deutsche Telekom experiments with G.fast. Soukup told BBWF, "We're going to have a field test in Frankfurt with G.fast and Fiber To The Building (FTTB.) We will know by the end of the year if this is the right way to go." Industry rumor has been DT going for G.fast in volume in 2019. Hint to Soukup: Yes it is. G.fast is working well at a dozen telcos I;ve talked to.
The details are surprising. DT is going for CORD, Open Source, Calix, and Radisys.
CORD (Central Office Reconfigured as a Datacenter) has been massively supported by AT&T. It's the heart of SDN at several telcos. Carl Russo reorganized Calix around software, hoping to land customers like DT.
Russo explained the advantage Calix has. "Telcos are moving to SDN to save money, including by going to lower cost equipment. The established vendors would be cannibalizing their own sales if they sold at the lower prices in their own base. For Calix, these would be new customers. We can do what we need to to win accounts."
Most European readers are not familiar with Calix, which is very strong in the U.S. They are primary suppliers to the midsized U.S. telcos and recently won a contract for NG-PON2 at Verizon. Verizon also requires open SDN, which is a challenge for Nokia-Alcatel to provide. Industry rumor was that VZ gave the NG-PON2 contract to Calix and Adtran to send a message to Nokia to get with the program.
Some years ago, I consulted on a broadband project in Vermont. I remember the CTO commenting he hoped Calix would get the contract because they had provided excellent service.
Iain Morris has a good article on CORD at DT, which had the Calix-Radisys as well.
