In 2016, G.fast looked very promising.
But only BT & Australia's nbn remain

Tweaking existing high end VDSL2 chip - and the pr. VDSL2 30 MHz profile 30a is generally described as 100 meg down, 100 meg up. Combine the two for your press release and you're at "200 megabits." Tweak a few parameters and you can claim "300 Mbps VDSL Right Now." Lantiq did that. Besides one-upmanship, it provides a way to telcos to advertise "300 megabits" to counter cable promises of 200, 400 and even a gigabit. Aethra, working with Lantiq, has delivered units to Orange Poland. I believe Broadcom is doing similar.
Kabel Deutschland CTO Lorenz Glatz two years ago explained his company strategy. "Whatever speed Deutsche Telekom, we'll offer twice the speed at the same price." Euro-DOCSIS 3 easily goes to 400 shared and delivers > 200 meg 95+% of the time. In 12-24 months, DOCSIS 3.1 will take that to a gigabit. Deutsche Telekom, building a 50-100 megabit VDSL network, fears they'll be left behind.
Telcos fearing aggressive cable companies are asking for more (advertised) speed. They are also disappointed in G.fast short reach and 16 home limit. Vendors are listening and hence promising a new class, Midi-DSL, mid-range bet G.fast and G.vector, promising higher speeds.
Here's Lantiq's release:
300 Mbps VDSL Right Now – Lantiq Introduces New Fiber To The Distribution Point Solution
Technology Media, Industry News & Articles
New Chipset and Systems from Leading OEMs Commercially Available Now
Munich/Neubiberg, Germany – September 30, 2014 – Lantiq, a leading supplier of broadband access and home networking technologies, today announced commercial availability of VINAX™ dp, an application-optimized Fiber To The distribution point (FTTdp) chipset. With the new offering, Lantiq provides Telcos and DSL Internet Service Providers (ISPs) with an immediate solution to counter competitive offerings from cable providers and to meet network performance goals set by government broadband initiatives.
The Lantiq VINAX dp chipset enables aggregated 300 Mbps over VDSL2 at distances up to 200m between a customer premise gateway and the fiber network distribution point. Based on Lantiq’s carrier-grade VDSL2 chips developed for line card applications, the new chip set operates in industrial temperature ranges and the low power consumption of the FTTdp unit enables installation in outdoor boxes with passive cooling.
FTTdp is available today and a cost-effective alternative to Fiber To The Home (FTTH) network topologies for many broadband access installations. FTTH requires the fiber to be deployed all the way into a customer’s premise, which is costly and may not be practicable in many scenarios. Since it can be line-powered from the customer premise, the FTTdp unit can be placed conveniently in carrier managed locations, while on the subscriber end, the standard VDSL CPE and power feeder is self-installed.
Key Features of the VINAX™dp
- Tightly integrated Lantiq carrier-class VDSL2 and GPON (FALC™ ON) solution
- 300 Mbps aggregated data rate with G.INP (retransmission) downstream and upstream
- Based on mature, future proof (VINAX CO platform) technology with demonstrated interoperability on both ends for GPON and VDSL links. Typical power consumption is 2.7 Watt for the VINAX dp chipset. The entire system consumes less than 6 Watts – including VDSL, GPON, DC/DC converter and all other active and passive components.
Lantiq has partnered with several leading equipment manufacturers including Alcatel Lucent, ZTE, T&W, Aethra Telecommunications and others for successful field trials of its FTTdp solution around the world and commercial systems are available now. Additional information is available in a video interview with Lantiq FTTdp expert Stefan Hirscher, a background article on the Lantiq FTTdp solution and at http://www.lantiq.com/fttdp
