With a dream to take India to the technological forefront, Anil Agarwal established a copper cable manufacturing unit in Aurangabad, India - the early beginnings of what would become STL.
To fuel growing aspirations as a technology pioneer, STL established an optical fibre cable manufacturing unit in Silvassa, expanding STL’s capabilities as well as its horizons.
We established our first optical fibre plant in Aurangabad, India - a move that would define STL’s identity for the next 25 years.
To fulfil ever-evolving customer needs, a data cable manufacturing unit was set-up in Dadra, adding breadth to STL’s growing portfolio. The unit remains one of India’s most advanced speciality cable manufacturing facilities, to this day.
Expanding our global footprint, STL’s first overseas manufacturing unit was set up in Haimen City, China. The greenfield facility was a result of a joint venture between STL and Jiangsu Tongguang Communication Co. Ltd. (TGCl), to fulfil China’s 100 million fkm annual demand for optical fibre.
Furthering our global strategy of building complementary partnerships in key geographical locations, STL formed a joint venture with Conduspar Condutores Eletricos Ltda. to establish a second overseas manufacturing unit in Curitiba, Brazil.
With the acquisition of Elitecore Technologies, STL’s goal was to diversify beyond the infrastructure vertical, and provide end-to-end solutions to its Telco partners. This allowed STL to offer industry leading software solutions for operations support, business support, and revenue management.
At STL, Innovation is in our DNA. To research and build accessible network technologies of the future, STL set up ‘Centre for Smarter Networks’ at Gurgaon, India. The centre is a part of STL’s growing list of innovation centres, which have collectively contributed to 376 patents over the years.
In line with STL’s identity as an end-to-end global technology leader and integrator of digital networks, STL acquired Metallurgica Bresciana - an Italian specialised optical cable manufacturer. The move greatly augmented our access to strategic European markets and opened new pathways for STL.
With a vision to make India the digital capital of the world, STL undertook various strategic initiatives in 2019:
STL made yet another strategic investment in ASOCS - a developer of open, disruptive, and virtualized Radio Access Network (vRAN) solutions, delivering 4G and 5G for cellular networks. This allows STL to offer end-to-end capabilities for a converged network, i.e. both wireless and wireline, and deliver full-stack solutions to enterprise and telco customers.
Expanded capacity for Optical Fibre Cable in Aurangabad.
STL established its first U.S. cable manufacturing plant in Kershaw County, South Carolina. The plant is strategically located closer to the customers in the region for speedier delivery.
