Telecom operators are looking for increased access speeds up to the ultimate fiber deployments reaching 10Gbps. But not everyone is ready to support the costly investments that need to be done to deploy a new network. Some may prefer to do it step-by-step by exploiting to the maximum their existing copper infrastructures.
Evolving Over Existing Infrastructure
Two technologies allow for such evolution, increasing the access speed from 100Mbps for VDSL2 vectoring: to 300Mbps for VDSL2 profile 35b; and up to 850Mbps-1Gbps for G.fast.
Technicolor has been a frontrunner in these two areas, with the first demonstration of G.fast in 2014, followed by a large-scale commercial deployment of G.fast-ready gateways in 2015; and the first commercial deployment of 35b gateways in 2016.
VDSL 35b is an evolution of VDSL technology, so it is already mature without any compatibility issues. Its deployment can be done from the street cabinet and its maximum speed has a reach of about 300m.
For operators who want a trusted and field-proven solution, the Technicolor DGA4130 is the perfect fit.
G.fast is a more disruptive solution as it uses a different modulation scheme and a different multiplexing. Its deployment is generally done from an extra network node because of its shorter reach compared to VDSL 35b, but G.fast is a technology that continues to evolve.
With its new 106b profile, G.fast also can be deployed from the street cabinet; and with the upcoming profile 212, its access speed can be doubled, up to 2Gbps.
For operators who want to deploy G.fast, the Technicolor DGA2231 is the platform of choice.
