G.fast：第二の波か？

サマリー

Summary

Around three years ago, G.fast appeared on the market as a very promising access technology, and key vendors were putting a lot of hope in this new copper-based technology which enabled speeds of more than 300 Mbps over a short copper line of a few hundred metres.

Although the number of G.Fast shipments was very low in 2017, a certain success in the market can be expected.

This report, the first available to analyse this market, proposes an update on G.Fast technology progress, telcos involved in G. fast today and includes G.fast subscribers forecasts up to 2021.
