In the ever-evolving landscape of telecommunications, the demand for faster and more reliable connectivity has never been higher. As technology advances and data usage soars with traffic predicted to double every 3 years, according to TeleGeography's 2023 Transport Network Forecast - telecom networks face the challenge of keeping up with the growing demands of users across various sectors. EXA Infrastructure (EXA), a leading data centre (DC) to DC connectivity provider, recognises the critical role that fibre optics play in shaping the future of telecommunications.
In this blog, we delve into the intricacies of the Shannon Limit and why the use of high-performing G.652D dark fibres is imperative in European telecom networks.
The Shannon Limit: Unveiling the Constraints
Claude Shannon's groundbreaking work in information theory led to the formulation of the Shannon Limit, a fundamental concept that establishes a theoretical upper limit on the error-free transmission of information over a communication channel. This limit is influenced by various factors, with signal-to-noise ratio playing a pivotal role. As seen on Infinera's blog, this law puts a cap on the amount of information that can be reliably transmitted over a given channel.
In the context of optical communication, the Shannon Limit highlights the importance of maximising the signal power while minimising noise power. This has profound implications for the design and performance of fibre optic networks, especially in the context of long-distance terrestrial connections and submarine cable systems as explained by Pioneer Consulting.
The Role of G.652D Dark Fibres
To address the challenges posed by the Shannon Limit, network operators turn to advanced fibre optic technologies. Low attenuation G.652D dark fibres emerge as a leading solution due to their superior performance characteristics. These fibres, designed to minimise attenuation, play a crucial role in pushing the boundaries of data transmission capacity.
EXA understands the significance of G.652D dark fibres and has strategically incorporated them into its network design and operations. By utilising these high-performing fibres, EXA ensures that its network can deliver and sustain unparalleled speed and reliability, meeting the demands of enterprise clients, NGOs, telecom carriers, and hyperscalers alike.

Low Attenuation: A Key Enabler
Attenuation, the loss of signal strength as it travels through the fibre optic medium, is a critical factor in determining the performance of a network. Low attenuation fibres significantly reduce signal loss, enabling data to travel longer distances without compromising quality. Besides EXA Infrastructure design, by minimising the numbers of connectors, splices, as well as the number of events during the first 20 kilometres of each span, not only when building its network but also and more importantly during its operational life, maximises the benefits.
As discussed in Ciena's insights, the evolution of submarine cable networks emphasises the need for low attenuation to support long-haul connections. EXA Infrastructure recognises this imperative and has meticulously designed its network with very low attenuation fibres, already committing to improve over 4200km, and to deploy over 3,800km of new routes, well ahead to any other provider in Europe. This commitment to low attenuation ensures that EXA's network can cater to the current and future needs of its diverse clientele.
