Relatively few businesses need a full fibre-to-the-premises (FTTP) broadband connection at present, it has been claimed.
Andrew Saunders, Head of Product Management & Marketing at Zen Internet, claimed that slower fibre-to-the-cabinet (FTTC) connections are more than fast enough for the vast majority of users.
FTTP broadband sees fibre connections used between the local telephone exchange and street cabinet, and cabinet and end user.
However, with FTTC broadband, a legacy copper connection - which reduces data transfer speeds - exists between the street cabinet and business or household.
Mr Saunders said business customers are "led to believe" they must have fibre broadband delivered directly to their premises, as anything less will "not be satisfactory".
"The government is working with the industry to try to deliver Europe’s fastest broadband network by 2015 and we hope that they succeed," he stated.
"But meanwhile, the needs of businesses can be met right now from existing FTTC options, and this is not being made clear."
Mr Saunders noted that more than half of all businesses and households across the UK can already take advantage of FTTC broadband - which offers up to 80Mb download speeds.
This solution avoids disruption and guarantees high performance and reliability, he said.
"Most organisations do not need the 330Mb promised by FTTP, and will find 80Mb more than enough," the expert added.
Telecoms giant BT is aiming to offer super-fast fibre broadband to two-thirds of the UK by 2015.
The broadband provider is also giving businesses and households the opportunity to sign up for FTTP on-demand, where customers pay for the installation of full fibre broadband at their property.
Mike Galvin of Openreach, part of the BT group, told the BBC that the new service will be a "game changer" for broadband delivery in the UK.
