Neterra taps Infinera for €12m network upgrade in Bulgaria

Neterra is modernising its Bulgarian backbone network using solutions from Infinera, a part of Nokia.

The €12 million investment will boost the data transmission capacity on Neterra’s DWDM (Dense Wavelength Division Multiplexing) network from 200 Gigabits per channel to 800 Gigabits per channel, helping the provider meet increasing demand among regional enterprises and provide reliable international transit through Bulgaria.

In addition to higher speeds, the network upgrade will provide greater flexibility via the implementation of ROADM devices - intelligent signal management cards that allow Neterra to configure new services entirely via software. Physical intervention and cable re-patching at intermediate points along the route will no longer be necessary, speeding up operations and reducing the risk of errors.

Pavel Marchev, Chief Technology Officer at Neterra, commented: “Our old network served us faithfully for years, but in certain sections, we have already reached its capacity limit. We have already signed contracts for services that the old network could not support. The new infrastructure is more stable, easier to maintain, and enables us to carry vast volumes of traffic for our internet users, NetIX members, and enterprise clients."

The first phase of the project covers key routes in Western and Southern Bulgaria, including Sofia – Ruse, Sofia – Plovdiv – Stara Zagora – Sliven – Kapitan Andreevo.

The infrastructure along these routes is expected to be fully active and operational within 3-4 months. The next phase of the project will cover the rest of the country, including Varna and Bourgas.
