WorldLink upgrades 650km backbone network in Nepal

12 July 2017 | James Pearce

WorldLink is partnering with Nokia to upgrade its 650km backbone network that runs between a number of Nepalese cities and connects the country to other countries including India.

NepalWorldLink is the largest fixed broadband provider in the Himalayan country and will now upgrade its backbone to offer 100G services, using Nokia’s 1830 PSS (Photonic Service Switch) DWDM (Dense Wavelength Division Multiplexing) technology.

The Nepalese telco says it is connecting 10,000 residential fibre to the home subscribers every month, resulting in the need to expand the capacity of its optical backbone in its biggest ever project in order to meet demand.

Samit Jana, CTO, WorldLink, said: "WorldLink has a commitment to Nepal to transform the communications landscape so that our people and enterprises thrive. 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."

The intercity network stretches from Kathmandu to Bhairahawa and Birgunj, whilst also providing connectivity outside of the Himalayan country.

Nokia's optical network technology will allow WorldLink to flexibly increase its network capacity, reach and density as the technology is powered by Nokia's Photonic Service Engine-2 with super coherent technology (PSE-2s), what it claims is the industry’s "most programmable chipset".

Sanjay Malik, head of India Market , at Nokia, said: "We are proud to be part of WorldLink's vision to transform Nepal's communications architecture by providing the first 100G transport network. Nokia's highly scalable optical platform will ensure low latency and high resiliency, and allow WorldLink to cost-effectively increase network capacity as needed.
