Nokia has announced the successful upgrade of RailTel’s dense wavelength division multiplexing (DWDM) national long-distance (NLD) network, undertaken in collaboration with its authorised partners. Nokia has deployed RailTel’s carrier-grade NAT (CG-NAT) and metro optical transport network across India. These initiatives collectively address the growing demand for high speed, resilient connectivity, driving operational efficiency and reducing costs.
Leveraging Nokia’s 1830 photonic service switch (PSS) and advanced transponder technology, the enhanced network achieves a substantial increase in transport capacity while minimising cost per bit. By reutilising RailTel’s existing infrastructure and previously unused channel spectrum. The deployment also introduces high-capacity Lambda transmission and express traffic lanes between cities, significantly improving overall network performance.
Commenting on the partnership, chairman and managing director, RailTel, said, “This collaboration represents a pivotal step in modernising our BNG, CG-NAT and optical transport systems. Through the integration of Nokia’s advanced technologies with our existing infrastructure, we are positioned to achieve exceptional efficiency. These enhancements will enable us to deliver superior, faster, and more reliable services to our enterprise and Broadband customers across India.”
Meanwhile, head, India sales for network infrastructure, Nokia, said, “At a time where demand for high-speed, resilient network services is constantly increasing, RailTel has put its trust in Nokia to ensure its critical network modernisation project is successful. We have unmatched credentials in supporting open network architectures which integrate into any customer ecosystem, and the use of our latest set of IP routers and optical transponders will help RailTel to reduce costs and improve operational efficiency.”
