Summary
- STL's new pre-terminated range spans 48 to 6,912 fibres.
- The highest-count cable is designed for campus, inter-building, and inter-row connections.
- Factory termination targets installation speed and pathway constraints in high-density data centres.
Connectivity supplier STL has expanded its Neuralis data centre portfolio with pre-terminated fibre trunk assemblies ranging from 48 to 6,912 fibres, targeting denser hyperscale and AI connectivity.
The range is divided between indoor assemblies from 48 to 576 fibres and indoor/outdoor cables spanning 144 to 6,912 fibres.
At the upper end, STL says the 6,912-fibre cable has an outer diameter of 32mm and is intended for campus, inter-building, and inter-row interconnects.
Indoor products can be supplied with MMC, MTP/MPO, and LC terminations using Base-8, Base-12, Base-16, and Base-24 configurations. STL also offers bend-insensitive single-mode fibre and OM4 multimode options depending on the application.
The assemblies are factory terminated and tested before delivery rather than being fully terminated in the field.
AI networking creates a physical cabling problem
AI infrastructure is increasing network bandwidth inside and between data halls. Large accelerator clusters depend on substantial east-west traffic between servers, while campuses also need high-capacity links between halls, meet-me rooms, network rooms, and external interconnection points.
That growth translates into a physical problem: every additional fibre has to pass through trays, ducts, conduits, risers, cabinets, and patching infrastructure whose dimensions may have been fixed years earlier.
STL’s pitch is therefore as much about pathway density as raw fibre count. Smaller-diameter high-count trunks allow more optical capacity to pass through an existing route, while pre-termination removes a portion of field splicing and connector work.
Factory termination can also shift quality control away from the construction site. That is useful where programmes are compressed and cabling work is taking place alongside electrical, cooling, containment, controls, and rack installation.
It does not eliminate commissioning. Fibre polarity, labelling, connector cleanliness, routing, bend radius, testing, and documentation remain critical, particularly at counts where an error can affect a large number of links.
STL’s highest-count indoor/outdoor assemblies use its rollable-ribbon technology and are available with low-smoke zero-halogen jacketing and sunlight resistance for outdoor routing.
The launch is global rather than tied to a named European data centre project. STL says it has manufacturing operations in North America, Europe, and Asia, giving the product relevance to European supply chains, but the announcement does not disclose a European deployment.
The broader trend is nevertheless important for facility design. Connectivity density is becoming another constraint that has to be coordinated early with building pathways and rack layouts rather than treated as a late-stage IT fit-out issue.
As operators design for 400G, 800G, and future higher-speed links, the capacity of cable trays and conduits can become a practical limitation even when switches and optics are available. Higher fibre counts in smaller physical packages are one response, but they also increase the concentration of network capacity inside individual cables.
The move towards pre-terminated, high-count assemblies therefore reflects the same pressure appearing elsewhere in AI infrastructure: more capacity has to be installed into finite physical space, on construction schedules with very little tolerance for rework.
