Nokia says it is helping Nepalese fixed-broadband operator WorldLink upgrade its 650-km backbone network with its DWDM technology to create Nepal’s first 100G transport network.

The intercity network stretches from Kathmandu to Bhairahawa and Birgunj, and provides international connectivity between Nepal and other countries including India.

WorldLink has 120,000 residential broadband subscribers and 5,000 enterprise broadband circuits. It is now connecting 10,000 residential FTTH subscribers every month, requiring the operator to meet ever-increasing demand for network capacity.

The broadband operator is deploying Nokia’s 1830 PSS (Photonic Service Switch) technology, which will enable it to flexibly increase its network capacity, reach and density.

“This is our largest project to date and it will allow us to provide ultra-fast broadband services for our mobile and fixed network subscribers in cities as well as rural areas across the country,” said WorldLink CTO Samit Jana.
