Calix Gfast Service Provider Survey: The Results are In!

Calix ran a Gfast survey with respondents from four continents. The extensive survey generated some very interesting results from the global service provider community. Results that echoed many of the key topics at this year’s Broadband World Forum in Berlin, but also others that did not quite follow the main thread of delegate sessions and vendor booths.

Yes, the survey mirrored the common belief that today's main use case for Gfast is solving the difficult logistical issues of meeting the broadband demands of MDUs and MTUs when fiber inside the building is not a feasible solution.

However, the most surprising to me was a question of what are the key advancements in Gfast that service providers are seeking before mass deployment.

BBWF, and the industry at large, have focused on getting more bandwidth over a copper loop.  But, as we can see from Figure 1, the service provider respondents to the Calix Gfast survey stipulated that the need to have higher density solutions to meet even the largest of MDUs was the biggest requirement and barrier to mass deployment.


This is exactly why Calix launched the new AXOS Gfast E3-48F DPU and E5-48F MDU solutions at the Berlin show.

With the power of AXOS, Calix is first to market and already trialing 48 port Gfast solutions that can mesh vector up to 96 Gfast subscribers in a single binder with Tier 1 service providers.

Also with the latest amendment 3 (212 MHz) chipsets, every user can experience true gigabit services and even multiple gigabits with the unique bonding functionality found in Calix AXOS.

This just highlights what survey respondents were seeking; the ability to offer easy-to-deploy services that mirror FTTH services, in low, mid, and now even high-rise MDUs.
