DESIGN & BUILD
Cabling inside the data centre has become a limiting factor in how quickly operators can add capacity. Fibre counts are rising, duct space is finite and AI-driven architecture shifts are pushing density requirements beyond what conventional microduct cable was designed to carry. Prysmian, long established in energy connections and long-haul digital links, is now moving inside the data centre through product development, manufacturing investment and acquisition.
Fibre miniaturisation lifts data centre cabling density Prysmian laid the technical groundwork in March 2026, when it introduced Sirocco Ultra, the first microduct cable to use 160 ยต m optical fibre. The cable holds 288 fibres within a 6.1mm diameter, giving a density of 9.9 fibres
