Redes Energeticas Nacionais (REN), the Portuguese Transmission System Operator (TSO), has renewed its optical transport network using Nokia packet DWDM/OTN technology.
REN’s optical transport layer connects more than 25 gas and electrical substations with 1,600 km of optical fiber. Nokia’s DWDM / OTN solution supports network slicing to guarantee capacity and latency for operational communications services up to 100 Gigabit Ethernet speeds, ensuring a high capacity long-haul transmission layer in REN’s private telecom network.
The deal follows the 2018 implementation of the Nokia DWDM / OTN technology for datacenter interconnection.
CT Head Enterprise Spain & Portugal, Nokia, said: “Following the 2018 project to connect REN’s datacenters, we are proud to build on their relationship and rollout this country-wide deployment with the support of our local partner Axians Portugal.”
Ines Lucas, IT Director, REN, said: “We have partnerd with Nokia and Axians to upgrade REN´s optical transmission network and provide maintenance support during its full lifecycle. It was a two year project and we were able to meet our requirements and initial plan throughout a very constrained period with all the pandemic logistic and human restrictions.”
