Low-loss high-density fibre: key to powering the next generation of data networks

In the face of rising bandwidth demands and space constraints, low-loss solutions can revolutionize data transmission with compact design and superior performance.

Growing adoption of high-density fibre in public networks and data centres is being driven by the escalating demand for higher bandwidth, lower latency, and more efficient data transmission. In data centres especially, transitioning to high-density fibre solutions is crucial to managing the surge in data traffic and supporting emerging technologies such as artificial intelligence. 

High-density cables allow more fibres to be packed into the same physical space, enabling better cable management in racks and conduits—an essential factor in both data centres and crowded public network ducts. These cables support higher capacity, accommodate exponential data growth, and allow operators to enhance speed and performance, simplify maintenance and deployment, and can be scaled up without the need for major infrastructure overhauls.

However, despite being designed for high performance, even high-capacity fibre cabling can suffer efficiency and reliability issues due to signal losses. These losses can stem from a variety of sources, including signal attenuation, bending, insertion issues, and connector or splice faults. Consequences range from reduced reach and increased bit error rates to packet loss and signal degradation.

Fortunately, advancements in fibre technology are addressing these challenges. High-density cables can now be enhanced with low-loss capabilities, thanks to high-performance optical fibres that combine industry-leading resistance to macro- and micro-bending with a reduced 200µm coating diameter. One such innovation is Prysmian’s BendBrightXS 200µm, which significantly boosts network performance by offering superior low-loss characteristics. This ensures extended reach and high-capacity transmission—even in the most demanding environments.

Engineered specifically for low loss, this optical fibre delivers optimal transmission across all communication bands, including the challenging L-band and U-band. It effectively minimizes bend-induced losses and power leakage, enhancing network reliability and offering stronger protection against data tapping and cyber threats. Its compact design also allows for tighter installations, reducing the physical footprint while still supporting ultra-fast data speeds.

The ColorLockXS coating system enhances mechanical reliability by providing strong resistance to environmental factors, mechanical stress, and aging. This coating, integrated into the secondary layer, eliminates the need for an extra 10µm of colour coating, allowing for further diameter reduction of the overall cable. The result is a highly durable fibre optimized for dense, high-traffic deployments that demand long-lasting performance and minimal maintenance.
