Constl, a subsidiary of Space World Group, has deployed Ciena’s WaveLogic 6 Extreme (WL6e) solution. This follows a successful live trial in which Constl achieved a 1 Tbps line rate on a single optical channel using WL6e across the 1,450 kilometre (km) Mumbai–Chennai route without the need for regeneration.
Commenting on the deployment, chairman and founder, Space World Group, said, “Since inception in 2023-just two years ago- Constl has deployed over 12,000 km of fibre and connected around 100 data centers across 13 Indian cities, powered by Ciena’s industry-leading optical technology. This milestone positions us to expand our terrestrial fibre network and deliver high capacity 800GbE services for the artificial intelligence (AI) era.”
Meanwhile, vice president and general manager, Asia Pacific, Japan and India, Ciena, said, “Constl is committed to developing networks tailored to hyperscaler requirements, and Ciena’s coherent optics are recognized 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.”
Using WL6e, Constl doubles fibre wavelength capacity from 800 Gb/s to 1.6 Tb/s when compared to the earlier WaveLogic 5 Extreme deployment, while reducing cost per bit. The upgrade also improves spectral efficiency and reduces power consumption.
