Capitalising on India’s burgeoning digital economy, digital infrastructure provider Constl has successfully tested and deployed a record-breaking 1 terabit per second (Tbps) line rate on a single optical channel across the 1,450 km Mumbai–Chennai route. The breakthrough, achieved in collaboration with global networking leader Ciena, utilised Ciena’s Wave Logic 6 Extreme (WL6e) solution on one of Constl’s most critical corridors, without the need for regeneration. Constl is a subsidiary of the Space World Group.
This milestone makes Constl India’s first digital infrastructure provider to achieve a 1 Tbps transmission rate over a long-haul distance. The WL6e upgrade is set to significantly boost Constl’s ambition to become the network of choice for hyperscalers operating in India. The deployment effectively doubles the fibre wavelength capacity from 800 Gb/s to 1.6 Tb/s compared to its earlier WaveLogic 5 Extreme deployment, delivering a strong competitive edge by increasing capacity while simultaneously reducing cost per bit, improving spectral efficiency and lowering power consumption.
“Since inception in 2023—just two years ago—Constl has deployed over 12,000 km of fibre and connected around 100 data centres across 13 Indian cities, powered by Ciena’s industry-leading optical technology,” said Ankit Goel, Chairman and Founder, Space World Group. “This milestone positions us to expand our terrestrial fibre network and deliver high capacity 800GbE services for the AI era.”Constl’s successful trial is also seen as a testament to the high-quality fibre infrastructure the company is laying across the country.
Amit Malik, Vice President and General Manager, Asia Pacific, Japan and India, Ciena, reinforced the partnership’s focus on future-ready connectivity. “Constl is committed to developing networks tailored to hyperscaler requirements and Ciena’s coherent optics are
recognised as the best-in-class platform for high-capacity AI services. Together, we are driving next-generation connectivity to support India’s digital future and AI ambitions.” Constl specialises in delivering advanced digital infrastructure solutions purpose-built for hyperscalers, telcos and OTT/CDN providers, operating a pan-India high-speed network. Ciena is a global leader in high-speed connectivity, known for building adaptive networks to support exponential growth in bandwidth demand.
