TalkTalk Business is entering a trial for G.fast through its wholesale and partner customers.
This follows the recent announcement that TalkTalk Business is extending the build out of its own FTTP, 1Gb full fibre network, beyond York and signals the intent to embrace the move to ultrafast connectivity.
G.Fast is a complementary technology to FTTP and can boost Internet speeds over the existing copper infrastructure (up to 330MB).
G.fast will be available during a trial rollout from April 2018, with launch expected in line with Openreach's own launch in the summer.
G.fast is available alongside ADSL and FTTC via the partners API or portal.
TalkTalk Business will launch an unlimited usage G.fast proposition, in line with its FTTC offering, meaning partners will pay a fixed monthly cost regardless of any increase in usage.
Pete Tomlinson, Commercial Director at TalkTalk Business, commented: "As businesses and consumers, we have developed an insatiable appetite for bandwidth and TalkTalk continues to embrace new technologies.
"As we continue to champion the drive towards a full fibre future, which for many is still too far away, G.Fast can play an important role in helping customers enjoy the speeds they deserve."
