Re-using G.fast over copper phone lines is an alternative but this is dependent on the line’s performance, which can vary from as low as 100Mbps up to 1Gbps as testified by a number of operators. With this variance in speed, G.fast does not offer operators a consistent data rate and it can be problematic to sell these high-speed services.

 

By utilizing the coaxial network, operators have an alternative to support a higher, consistent frequency range and provide Gigabit and MultiGigabit services effectively. In competition with cable-TV service providers that are offering DOCSIS, operators have been deploying Gfast technology over Point-To-Point (P2P) coaxial networks where such networks are readily available.
