Sterlite Tech launches pre-terminated fiber trunk assemblies for data centres; shares rally 704% YTD

According to a regulatory filing dated September 24, the company launched pre-terminated fiber trunk assemblies ranging from 48F to 6912F.

The firm further stated that the newly launched fibre cables are 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.

The company said that its pre-terminated fiber 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,” STL added.

Commenting on the development, Dr Badri Gomatam, CTO, STL, said: “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.”
