From the country that brought you the Autobahn comes word that DOCSIS has broken the 1 Gigabit-per-second barrier in the field.
Kabel Deutschland announced last Friday that it had achieved a download speed of 1.17 Gbps in a field trial conducted in Hamburg with Cisco Systems, over an 862-MHz system. In the Hamburg system, the MSO currently offers customers 100-Mbps Internet access, plus more than 100 digital and 32 analog TV channels. According to Kabel Deutschland, the field trial delivered 1 Gbps in addition to these services.
“It will take a few more years until Internet applications and content exists that actually allow our customers to fully utilize as much as 1 Gbps,” Kabel Deutschland CTO Lorenz Glatz conceded in the company’s announcement.
But given that the average demand for bandwidth of a household in the KD network increased by 500% from 2006 to 2010, Glatz continued, “the question is not if but when this time will come…. In any case, the cable network is already prepared today.”
Cisco provided the CMTS and the EuroDOCSIS 3.0-based broadband equipment for the customer premises in the Kabel Deutschland test. Publicly held Kabel Deutschland has about 8.9 million customers.
KD’s field test was carried out at a multidwelling unit in Hamburg. The bandwidth tests were conducted both on an individual computer and over a multiroom network on several computers, and involved downloading large files from German university servers and DVDs.
In the States, Comcast and Time Warner Cable both say they’ve tested DOCSIS 3.0 at 1-Gbps in the labs. Meanwhile Verizon has tested 10-Gbps downloads over the fiber-to-the-home FiOS network (see FiOS Test Struts 10-Gig Stuff).
