Supporting 30A should win Japanese & Korean market. The biggest problem for most telcos deploying DSL is that until now, no one made a DPU with more than 16 ports. HFR of Korea has the first 24 port DPU and a giant customer ready to go. $15B SK Telecom is Korea's largest wireless carrier and #2 in fixed. There are 9M apartments in Korea served with VDSL and copper LAN, most running at 100 megabits.
Korea Telecom is actively deploying GIGA Wire, their version of G.hn, for higher speeds. They intend to upgrade 95% of those units by the end of 2017. SK needs to respond quickly. Japan is similar; millions of their "fiber" lines are fiber to the basement + VDSL. Korea and Japan used an advanced version of VDSL, using 30 MHz rather than the 17 MHz common elsewhere. Ikanos, now gone, had long been the preferred vendor. Sckipio is first with G.fast chips designed to work with VDSL 30a.
Curtis Frankenfeld of Century recently told me, "I would like G.fast to support a larger vectoring group than the current 16 ports."
