ADTRAN expanded its Software-Defined Access portfolio with second-generation Gfast products, allowing for the transparent extension of fiber-to-the-home (FTTH) service capabilities. This marks the industry’s first commercially available gigabit-capable Gfast solution, meeting the need of customers to fully participate in a global hyper-connected world, according to ADTRAN. ADTRAN says it is the first to deliver Gfast systems that conform with Amendment 3 of the ITU-T G.fast standard, which doubles the usable spectrum from previously 106 MHz to 212 MHz.
