End-to-end passive optical connectivity for homes and business. From the central office to the inside the home.
STL delivers fiber and copper structured cabling for internal networks, alongside high-density optical backbones for metro and long-distance connectivity—ensuring seamless, scalable enterprise infrastructure.
Structured cabling and LAN solutions—fibre, copper, and FTTA for enterprise networks.
STL manufactures its own glass preforms; these are the glass cylinders from which all optical fiber is drawn. Owning the base of the supply chain is important, especially during times when fiber demand spikes.
This fiber independence enables STL to develop specialty fibers as we did with Multi-Core fiber (MCF), bend-optimised 200µm, 180 & 160µm formats ; these are the fiber technologies the next generation of AI GPU connectivity will be built on.
With 30 years of industrial-scale fiber manufacturing, STL has been the fiber backbone for network builders across Asia, North America, and Europe.
No two data centers are same and therefore STL cocreates solutions which are tailor-made for your data center build.
