In 2016, G.fast looked very promising.
Thousands worked at developing and deploying.
It wasn't enough.
Most carriers are investing
in fiber or 5G instead.

Telebyte is also ready with 35b vectored test equipment. You want to catch equipment problems in the lab because serious field trials cost millions. But how do you test the 300-page G.fast standard? Michael Breneisen's company chose to work closely with the Broadband Forum and their equipment is designed around the Forum's test suite. They've outfitted a lab at the University of New Hampshire which hosts the Forum's interoperability testing.
Breneisen tells me the most frequent problems in early G.fast equipment were in the stability of FEXT cancelation and noise protection. Once discovered, manufacturers corrected most of them. Looking forward, he believes the industry needs to be able to test sucessfully Interoperability between chipset vendors.
Field tests reveal even more. TNO's Rob van den Brink gave an outstanding presentation at last year's Ultra Broadband Forum. He offered surprising observations from DSL field results in the Netherlands. I always remain skeptical of company claims until we have results from 10,000 customers.

Telebyte Announces Release of G.fast Cable Farm Automation SwitchBy PR Rocket on January 18, 2016
Next-Gen Switch Designed Specifically for Automating G.fast and VDSL2 Vectoring Testing
Hauppauge, NY (PRWEB) January 18, 2016
Telebyte, a US-based global xDSL test equipment solution provider, today announced the release of the Model CFA-24 Transparent Cable Farm Automation Switch – the only switch on the market designed for testing the Broadband Forum’s ID-337 and TR-249.
The 24-channel, electrically neutral device allows up to twenty-four incoming cable farm lines to be switched to five different copper loop segments. Operating in a frequency band up to 212 MHz, the CFA-24’s superior performance and transparency facilitates lab-grade testing of VDSL2 Vectoring (including Profile 17a and Profile 35b) or G.fast devices where accuracy is extremely important.
The CFA-24 is the company’s first product designed for programmatic control of multiple copper loop segments. Line lengths and increments are set without re-cabling. The user makes connections once then switches loop segments in (or bypasses them) as needed through a web browser. Remote commands can be used to set line lengths for test automation. Additional features include Micro-Interruptions and support for Reverse Powering (G.fast).
In keeping with the modular approach to most of Telebyte’s products, units may be added as testing requirements expand or budget becomes available. This allows customers to purchase an initial system and later extend the number of loop segments to as many as fifteen and/or expand the number of channels to as many as needed by purchasing additional units.
“Our customers were looking for a way to avoid connecting and disconnecting loop segments in their cable farms manually. They wanted to simply switch in or bypass segments programmatically,” said Michael Breneisen, President of Telebyte. “Customers reported dissatisfaction with other products that were repurposed for this type of testing so we decided to design a product from the ground up to meet both VDSL2 Vectoring and G.fast testing requirements. We are very pleased this release coincides with the high demand for ID-337 G.fast Certification testing and TR-249 testing.”
Finally, the CFA-24 may be used with Telebyte’s noise generators and injectors to add alien crosstalk, impulse, RFI and more for realistic testing
Telebyte Announces New Release of G.fast Universal Noise Generator
First commercially available Noise Generator to support ID-337 G.fast Certification testing
(PRWEB) January 14, 2016
Telebyte, the leader in G.fast test equipment, today announced the release of the Model 4902 Universal G.fast Noise Generator. The next-gen solution is the only commercially available noise generator on the market that is fully compliant with the Broadband Forum’s ID-337 Certification Test Plan.
The solution builds upon its feature-rich predecessor, the popular Model 4901 which is already used around the world by most major service providers and equipment vendors. The modular design allows for expandable configurations from 2 to 24 noise outputs in portable or rack-mountable versions.
Telebyte includes user-friendly configuration software that allows the user to select and build a wide variety of complex impairment models that may impact G.fast deployments. These include background Gaussian noise, high frequency impulse noise (PEIN, SHINE), FM radio, Broadcast TV, Spark Plug Ignition noise, PLC noise, Reverse Power Feed noise and more. In addition, user-defined files in several formats (such as MATLAB. CSV and Excel) may be imported.
“Several major North American and European Service Providers are using Telebyte’s G.fast test gear to evaluate the performance G.fast technology,” said Michael Breneisen, President of Telebyte. “The equipment is in great demand. With our ability to meet this need we are now recognized as the established leader in the G.fast test equipment area.”
