The UK does not yet figure in a chart of the top 30 global nations for fibre-to-the-home (FTTH) broadband services.
Based upon research conducted by the FTTH Council Europe, South Korea has the highest penetration rate, ahead of the UAE, Hong Kong, Japan, and Taiwan.
Next on the list - by FTTH subscribers per household - is Lithuania, which has the greatest proportion of 100Mb broadband customers in Europe.
In the UK, Virgin Media and BT are continuing to extend their 100Mb broadband reach, while smaller service providers are also creating local ultra-fast networks.
But once again, the UK has failed to break into the global elite for FTTH services, with relatively few households signing up for ultra-fast broadband at present.
Chris Holden, President of the FTTH Council Europe, said his organisation was concerned at the lack of a new European entrant to the global FTTH elite.
But on the positive side, he said there has been steady growth in fibre penetration in the region over the last year.
"Still there is a long way to go to reach the Digital Agenda targets of the European Union to ensure that more than 50 per cent of the European households will use broadband connections of 100Mb or more in 2020," Mr Holden added.
