Pune-based Sterlite Technologies (STL) has laid off approximately 100 employees, including senior executives, as part of a restructuring plan. The move is aimed at cutting operational costs, with non-core functions being affected the most. The company's decision comes amidst increasing business pressure and competition from multinationals in the optical networking sector. STL recently sold off its telecom and software units to a US-based firm. The company's order book for the current year stands at around ₹10,500 crore, with the optical networking business contributing nearly 80% of its overall revenue.
