Sterlite Technologies Ltd has launched its CONCAT FTTH solution in the United States through its U.S. subsidiary, STL Optical Connectivity NA, LLC (STLOC). The launch follows the successful completion of field trials on the networks of one of the largest telecom service providers in the country. The solution targets a reduction of up to 71% in fiber deployment labor costs by eliminating most field splicing through factory-assembled, pre-connectorized fiber segments that deliver plug-and-play installation. This development is significant for digital infrastructure providers seeking faster fiber rollouts with reduced deployment complexity and labor dependency.

CONCAT FTTH Solution: Key Highlights

The CONCAT FTTH solution is designed to address cost efficiencies in fiber network deployment. The following table summarizes the key details of the launch:

Technical Features and Benefits

CONCAT simplifies fiber deployment by shifting critical fiber preparation and termination into a controlled manufacturing environment. This ensures consistent quality, faster installation, and lower operational risk in the field. The solution features a concatenated, pre-connectorized MPO-to-LC cable assembly integrated with a versatile enclosure and cassette architecture. Its spliceless, modular design enables plug-and-play installation, which helps eliminate most field splicing, reduces truck rolls, and minimizes rework. By reducing installation time and field errors, CONCAT significantly improves overall project economics for new builds, network expansions, and overbuild programs facing aggressive broadband coverage and speed targets.

Strategic Market Entry

The introduction of the CONCAT FTTH solution in the U.S. underscores Sterlite Technologies' focus on delivering cost-effective fiber deployment offerings to one of the world's largest broadband infrastructure markets. Ryan Chappell, Vice President of Connectivity at Sterlite Technologies, stated that the solution is engineered to address the pressure to build faster and at lower cost amidst skilled labor constraints. Recently, CONCAT was recognized by one of the industry's leading innovation awards for its technical merit, performance impact, design uniqueness, and overall contribution to advancing optical communications.

Sterlite Technologies has secured a definitive victory in its European patent dispute with Fujikura Ltd, following a final, binding, and non-appealable ruling by the European Patent Office (EPO) Technical Board of Appeal. The decision, issued on June 24, 2026, revokes Fujikura's European Patent EP 3796060 in its entirety, effectively resolving the UK patent litigation concerning the company's Celesta cable family in favour of Sterlite Technologies. This development removes a significant legal overhang and strengthens the company's intellectual property position across the UK and Europe.

The company disclosed this update pursuant to Regulation 30 of the SEBI (Listing Obligations and Disclosure Requirements) Regulations, 2015. The ruling by the EPO's highest appellate body serves as a powerful affirmation of the strength of Sterlite Technologies' global IP position and its R&D capabilities. The company is now actively pursuing the recovery of legal defence costs incurred during the proceedings from Fujikura.

Details of the Litigation

The following table outlines the key particulars of the litigation and the latest update:

The filing confirms that there is no settlement involved, nor are there any claims or penalties applicable to the company. The company's intellectual property is protected by a 785 patent portfolio spanning major global markets. Sterlite Technologies' fully vertically integrated capability ensures quality control and supply chain resilience for its global customers.
