Calix, Inc. (NYSE: CALX) is using this week's Broadband World Forum in Berlin to launch a pair of 48-port Gfast nodes that support Amendment 3 of the ITU-T standard. A Tier 1 service provider the company did not further identify has the nodes in its labs, Calix adds.
E3-48F Gfast Remote Node (sealed distribution point unit, or DPU) and E5-48F Gfast Node leverage the capabilities spelled out in Amendment 3 of the Gfast specifications, which will enable the nodes to support symmetrical 2-Gbps capacity.
Among other things, Amendment 3 expands the spectrum over which the nodes will operate to 212 MHz. The spectrum stretch, combined with the use of coordinated dynamic time allocation (cDTA) and bonding, enable the 2-Gbps capacity. Calix also mentions the ability to support vectoring for up to 96 ports. All of these capabilities jibe with Sckipio's recently announced SCK-23000 chipsets (see "Sckipio SCK-23000 chipsets support Gfast Amendment 3 for 2-Gbps transmission"). Calix supplied a quote for Sckipio's announcement of a 96-port DPU reference design as well.
Calix positions the new AXOS enabled nodes as enabler of high-speed broadband service delivery to subscribers in multiple dwelling units (MDUs).
"The gigabit experience is fast becoming table stakes for service providers to capture and retain broadband-savvy subscribers. As such, service providers must find a way to deliver this experience, no matter where a subscriber is located," explained Teresa Mastrangelo, founder and principal analyst at Broadbandtrends, via a Calix press release. "With the introduction of the new Calix solutions that support Gfast Amendment 3, service providers now have a more streamlined and economical approach to meeting these demands for subscribers in MDU locations and differentiating themselves through a consistent service offering across copper and fiber."
The E3-48F and E5-48F will be on display in Booth A119 at the Broadband World Forum.
