Unsere unglaubliche Reise von Jahren

  1. 1988

    Humble Beginnings, Bold Ambition

    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.

  2. 1993

    Entering the World of Optical Fibre

    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.

  3. 1995

    The First Chapter in the STL25 Story

    We established our first optical fibre plant in Aurangabad, India - a move that would define STL’s identity for the next 25 years.

  4. 2002

    A Growing Portfolio of Customer Needs

    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.

  5. 2012

    Making Inroads Globally

    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.

  6. 2013

    Next Destination, Brazil

    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.

    2015

    Becoming An End-to-End Solutions Provider

    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.

  8. 2017

    Building a Future-ready STL

    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.

  9. 2018

    Italy Comes Calling

    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.

  10. randeep-sekhon-airtel

    2019

    Made in India, for the World

    With a vision to make India the digital capital of the world, STL undertook various strategic initiatives in 2019:

    Building one of the world’s largest greenfield semiconductor-grade optical fibre preform plants - Gauav, in Aurangabad, India.
    Acquisition of UK-based Impact Data Solutions (IDS) to strengthen our design and deployment offerings for hyper scale data centres
    Strategic partnerships with various entities like TIP, ONAP, O-RAN, and ONF to create higher-speed, lower cost, more secure, programmable, and more reliable networks for the future.

  11. 2020

    Converging Networks for the Market

    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.

  12. 2021

    New OFC plant

    Expanded capacity for Optical Fibre Cable in Aurangabad.

  13. 2023

    First plant in US

    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.
