STL Enhances Neuralis Portfolio with Pre-Terminated Fiber Trunk Assemblies to Power Hyperscale Data Centers

STL’s Pre-Terminated Fiber Trunk Assemblies include Indoor Pre-Terminated Fiber Trunk Assemblies (48F–576F) and Indoor/Outdoor Pre-Terminated Fiber Trunk Assemblies (144F–6912F).

STL (NSE: STLTECH) has strengthened its Neuralis Data Center portfolio with Pre-Terminated Fiber Trunk Assemblies ranging from 48F to 6912F. This is a high-density cabling portfolio purpose-built for hyperscale and enterprise data centers navigating an unprecedented surge in bandwidth demand driven by AI, cloud and high-performance computing workloads.

Hyperscale and data center operators are under constant pressure to bring capacity online faster, in less physical space, and with near-zero tolerance for field-installation error. As fiber counts climb, duct, tray and conduit space becomes the real constraint on how fast a data center can scale. Operators are shifting decisively towards connectivity that arrives factory-terminated, 100% tested, and ready to install for all connections across the data center.

STL’s Pre-Terminated Trunk assemblies combine ultra-high fiber density with a slim cable form factor, so operators can route more capacity through the same pathways, trays and conduits without compromising bend performance or long-term reliability. These offer premium factory-controlled optical performance on a variety of connectors that enable fast, economical installation. 

Key Applications

• Indoor Pre-Terminated Fiber Trunk Assemblies (48F–576F): Designed for high-density MMC, MPO and LC terminations inside the data hall, meeting ANSI/ICEA S-83-596 and UL OFNP (plenum) / OFNR (riser) cable standards, with cable diameters as compact as 5.8 mm (48F) scaling to 12.2 mm (576F).
• Indoor/Outdoor Pre-Terminated Fiber Trunk Assemblies (144F–6912F): An ultra-high fiber count portfolio built for campus, inter-building and inter-row interconnects, scaling all the way to 6912 fibers in a single cable while remaining a manageable 32.0 mm in outer diameter — supported by OFNR/LSZH jacketing and UL 1651-rated sunlight resistance for long-term outdoor exposure.

Key Features

• High-density, small-diameter design: From 48F trunks at 5.8 mm OD for in-rack and row connectivity, up to 6912F I/O trunks at 32.0 mm OD for campus-scale backbone links enabling significantly more capacity per pathway at every layer of the network.
• Application-ready connector options: Factory termination in MMC, MTP/MPO and LC formats, in Base-8, Base-12, Base-16 and Base-24 configurations, to match diverse switch and patch-panel architectures.
• Fiber choice for every application: Available in single-mode ITU-T G.657.A2 fiber (200 µm or 250 µm) for bend-insensitive, space-constrained routing, or for indoor in OM4 multimode fiber for shorter-reach, cost-optimized links.
• Engineered for fast, reliable splicing at scale: Both indoor and I/O use STL’s patented IBR rollable ribbon technology with innovative color-coded bonded ribbon design, enabling faster and more accurate ribbon identification
• Guaranteed optical performance: Every assembly is 100% factory tested, with Ultra Low Loss connector performance grades available across both portfolios to meet the most demanding budget requirements

“Every data center customer we work with is trying to solve the same equation – more capacity, less time. That’s exactly what this extension of Neuralis portfolio is built around. Our Pre-Terminated Trunk Assemblies are designed for dense networks, they are pre-tested, ready to connect on arrival, and flexible. This is connectivity built for how data centers are actually being constructed today; high density, tight timelines, zero room for error,” said Dr. Badri Gomatam, CTO, STL.
