Gfast:Should I stay or Should I go now?

Gfast question blog

As a middle-aged Brit, I have a strong affiliation with punk rock bands such as The Clash and their iconic song "Should I stay or should I go." Now, what has this got to do with Gfast I hear you ask? Well, it's basically the line in the chorus "If I go, there will be trouble, and if I stay it will be double."

Conversations with service providers regarding when they deploy Gfast is very similar to that. Many are asking whether they should wait for 212Mhz solutions or go now with 106Mhz.

The question I always ask in return is - what problem are you trying to solve by deploying Gfast? How are these intended services going to provide your competitive differentiation?

Most answers have been that they want to offer exactly the same services over Gfast as they can do over fiber. Why? So, they can stop losing customers to cable operators or fiber overbuilders.  

Calix, thanks to its AXOS driven Gfast solutions, can deliver commercially available services to meet service providers' actual target service goals. The introduction of Gfast 106Mhz bonding and cDTA means you can offer a gigabit symmetrical service today. Gfast 212Mhz future solutions provide a path to offer a very similar level of performance but across a single copper pair. However, this will only be possible for the shortest of loop lengths and without cDTA, it will remain a gigabit asymmetric service. 

Depending on the copper type and quality, both our existing 106Mhz cDTA bonded Gfast live deployments, and our testing of the future 212Mhz chipsets enable a reliable gigabit experience at up to circa 150 meters or 500 feet.

Investing in AXOS using today’s Gfast 106MHz helps service providers turn up gigabit services in minutes not days where competitive pressure demands it and enables common services across all fiber and copper access types. AXOS zero-touch provisioning streamlines system installation and remote diagnostics minimize time spent in the field.

As AXOS can uniquely work across anyPHY™, the same training, planning, and service creation investment today can also seamlessly be utilized tomorrow for future Gfast 212MHz deployments. Therefore, service providers can instantly benefit from all the same advantages and the same gigabit services of the currently available cDTA bonded solutions while offering greater density and economies of using just a single pair.

So, when it comes to Gfast 106 vs. 212Mhz, should you stay or should you go now? Can you allow your competition to decide for you? Maybe your customer churn is already telling you the answer? With AXOS as a true SDA platform, the investment will never be wasted.
