Greetings from STL!

I am delighted to welcome you to the first part of the STLescope - Unravelling the Future Series .It's great to e-meet you again.

2021 marks the beginning of a decade-long network creation cycle. STL had anticipated these shifts and has been working consistently to open up the path for nonlinear growth. We have understood that future networks will be highly scalable and agile and will require best-in-class design and capabilities. They will be built on four key technology confluences - the convergence of wired and wireless, a combination of connectivity and compute, disaggregation of hardware and software, and closer to the edge . Over the years, we have been developing these capabilities spanning optical, system integration , and virtualized access to solve the networking challenges of the industry and innovating for the next-gen networks.

We have outlined three strategic levers to drive our future ambitions. These 3 levers are:

• Grow optical business
• Globalise system integration
• Build disruptive, open-source Access Solutions

Access Solutions is a strategic business lever for STL that entirely focuses on the development of solutions that adhere to open networking principles to address 5G wireless and last-mile fixed access (FTTx). In a short span of two years, this business unit has well progressed in its vision of being the open networking leader.

Come join us for an engaging discussion exploring STL's remarkable Access Solutions journey that would shape our growth in the open networking space. We look forward to meeting you at the virtual event.

Following this technology learning session, we will keep the floor open for Q&A to address your queries. We look forward to seeing you at the event.
