Calix Catches Ethernet Fever
To tie the new E7 platform to this week's TelcoTV 2009 event in Orlando, Fla., Calix is emphasizing the industry's expectations of a video-heavy future for Ethernet networks.
The E7 is an all-Ethernet alternative to C7, Calix's multiservice platform. But there's more afoot than that. The small E7s -- one rack-unit pizza boxes with two slots apiece -- pack 100 Gbit/s of switching capacity, and 10 of them can be hooked up to perform as a single 1-Tbit/s switch with one IP address.
The E7 still targets access, though. Its first linecards sport Gigabit Ethernet and GPON ports with 10-Gbit/s Ethernet uplinks. But Calix thinks the terabit factor will come into play eventually.
"Each individual port and each individual subscriber is going to be utilizing tens of megabits [per second] of capacity in order to address their demand over time. We built this with headroom for a 10- to 15-year life cycle," says Geoff Burke, Calix's director of marketing.
He says Calix wanted an all-Ethernet box because the company couldn't ignore the center-stage role Ethernet is taking in carriers' plans. (See AT&T: Ethernet Is It .) Multiservice boxes like the C7 allow for a cautious migration to Ethernet, and the E7 was built with that strategy as well. Even though it's designed to be a very big switch, carriers can start with just one pizza-box. "You don't have to bet the farm that you're going to have high take rates on an advanced service in a part of your network," Burke says.
