STL also showcased the power of this optical fibre innovation through a live 400G network transmission with real-time traffic simulation. This Make-In-India innovation is laying the groundwork for the scale-up of advanced technologies like quantum communications and silicon photonics.

STL's Multicore fibre leverages Space Division Multiplexing in 7 and 4 core fibre to achieve ultra-high transmission capacity per fibre within the same diameter. This marquee fibre was deployed in the Advanced Optical Communications (AOC) Test Bed project last year to evaluate its transmission performance with advanced technologies in on-field conditions. This project is run in collaboration with DoT and IIT Chennai.

India's top researchers and academicians hailed STL's work on the multicore fibre as a breakthrough for revolutionary technologies like Quantum Communications and Silicon Photonics.
