CityFibre is the UK’s largest open access, fibre-only operator, providing services in cities, towns, and villages across the country.
In this video, David Tomalin, CityFibre’s Group Chief Technology Officer, discusses how the company’s full-fibre network is helping underpin the UK’s digital economy, expand connectivity, and support digital inclusion.
He also explores CityFibre’s approach to sustainability, including improving power efficiency, reducing equipment waste, and maximizing the lifecycle of network components. He shares how Ciena’s technology and thought leadership support these goals, including CityFibre’s decision to use Ciena’s RLS platform as part of its core national backbone and foundation for future network growth.
