- Cityfibre’s 5.5 GB service more than doubles its previous fastest broadband speed nationwide
- XGS-Pon upgrade enables Multi-Gigabit Internet speeds for home and businesses throughout the UK
- With 85% coverage, city fibers move rapidly toward full British network development this summer
City fibers have introduced a new 5.5 GB symmetrical broadband product aimed at increasing the benefit of ISPs (ISPs) throughout the UK.
The offer double more than the company’s previous fastest service and is part of a its wider upgrade to XGS Pon technology, which supports speeds up to 10 GB.
This upgrade is reportedly completed across 85% of City Fibers’ network, with full roll -out expected later in the summer of 2025.
City fibers Ultra-fast broadband
“Britain’s full fiber future is here thanks to Cityfibre’s powerful 10 GB XGS Pon network. Our ISP partners are already connecting customers with speeds over 2 GB and exceeding expectations when it comes to quality and reliability, but our next generation of full fiber will set a new standard for what is possible,” Greg Mesch said, City Fiber CEO.
City fibers are a wholesale provider, which means it will not sell directly to end users. However, the ISP partners will be able to offer a number of services with this new infrastructure, with the new offer designed to support ISP partners who want to offer multi-gigabit packages for homes and businesses.
City fibers say the service will be available nationwide and has suggested that even faster speeds – potentially 10 GB – are expected to be launched by 2026.
This would further expand the competitive landscape, especially compared to BT Openreach’s current top-tier service, maximizing 1.8 GB of downstream and 0.12 GB upstream.
“City fibers began to challenge the established companies and bring elections and competition to the British market,” Mesch added. “This is another huge step-forward that gives ISP more power and flexibility than ever before and brings affordable multi-gig speeds and an unmatched experience for millions of British consumers.”
Developments could have consequences for consumers searching for the best broadband agreement, especially if providers start offering more competitive price levels for multi-gig speeds.
However, the practical need for such a high bandwidth, as most home users typically require much less capacity for daily use, such as streaming, video calls and games.
The introduction of symmetrical 5.5 GB speeds may be more relevant to companies and power users than to the average household, to fully utilize this speed, consumers also need compatible equipment, such as a decent WiFi router or mobile router.
