RailTel modernises long-distance, metro optical networks across India | Computer Weekly
"In an industry where the demand for high-speed, resilient network services is constantly increasing, Indian railway ICT service provider RailTel has engaged Nokia to supply core technology for a critical network modernisation project that sees the upgrade of its dense wavelength division multiplexing (DWDM) National Long-Distance (NLD) network. With a pan-India optical fibre network exceeding 64,000 route kilometres and two Tier-III certified datacentres,"
"Nokia technology is already at the heart of RailTel's Carrier-Grade NAT (CG-NAT) and metro optical transport network across India, and the companies say their initiatives collectively address the growing demand for high-speed, resilient connectivity, driving operational efficiency and reducing costs. The latest partnership adopts a supplier-neutral, open-network approach, fostering future innovation and technological advancements across RailTel's optical footprint and the upgrade of RailTel's DWDM NLD network, undertaken in collaboration with its authorised partners."
RailTel has partnered with Nokia to modernise and upgrade its dense wavelength division multiplexing (DWDM) National Long-Distance (NLD) network using Nokia's 1830 Photonic Service Switch. RailTel operates a pan-India optical fibre network exceeding 64,000 route kilometres and maintains two Tier-III certified datacentres while providing services including MPLS-VPN, telepresence, leased lines, colocation and datacentre platforms. RailTel aims to transform over 6,115 railway stations into digital hubs via public Wi-Fi and supports national initiatives such as BharatNet and the Indian National Knowledge Network (NKN). The collaboration emphasizes supplier-neutral, open-network design to boost resilience, efficiency and future innovation across the optical footprint.
