Gigabit experience over copper for every MDU

Not all Gfast is the same. Future-proof your Gfast deployments with next generation Calix AXOS solutions

The world’s population is migrating to MDU’s, therefore to be successful service providers must have a strategy to deliver exceptional services to subscribers regardless of where they live.

By leveraging existing copper and coaxial wiring, technologies like Gfast enable service providers to deliver gigabit services to hard to serve MDU markets.    


AXOS continues to increase innovation and speed deployment

AXOS helps GLDS reduce OSS/BSS integration time by 80% and accelerates service provider time to revenue.

“We were not only surprised by the speed of our first integration…we were thrilled by how much easier it is for us to maintain…”

“We were surprised when we integrated the E9-2 System in four weeks…” 

--Garrick Russell, COO and President of GLDS

Frequently Asked Questions about Calix AXOS Gfast Solutions

What is Gfast?

  • Gfast (ITU-T G.9700/9701) is a fiber-to-the-distribution point (FTTdp) architecture that provides fiber-to-the-home like speeds with the self-installation aspects of ADSL.
  • Utilizes very short loop lengths, typically no longer than 400m, but is optimized for 250m.
  • Unlike VDSL which uses Frequency Division Duplexing (FDD), Gfast uses Time Division Duplexing (TDD).
  • Advantages include a variable DS/US asymmetry ratio, support for low power states, and discontinuous operation which allows trade-offs of throughput vs. power consumption.

What are the real benefits of Gfast A3?

  • Gfast A3 offers higher DENSITY, lower CAPEX (cost/port) as well as lower OPEX (minimized loop conditioning). A Gfast A3 vectoring group scales to 96 ports which applies to some buildings that use OSP wiring.

What are the advantages of cDTA?

  • cDTA improves Gfast upstream performance by four or five times by dynamically balancing upstream and downstream capacity to match residential traffic patterns in real-time.
  • Enables symmetrical gigabit services with Gfast and puts service providers in a leadership position against their competition as they can exceed the speeds of DOCSIS-based offerings.

How does vectoring enable service providers to reap the full benefits of Gfast?

  • Vectoring has eliminated many of the issues and concerns related to using higher frequencies on twisted copper pairs (e.g. generation of crosstalk).
  • Service providers utilize vectoring to cancel this crosstalk and allow each line to perform to its potential. This noise cancellation technology allows for higher speeds, both downstream and upstream.
  • Vectoring also brings significant performance gains.
