Nokia says it has collaborated with Netia of Poland to field trial the telecom technology provider’s Photonic Service Engine 3 (PSE-3) super coherent technology. While Nokia has announced other field trials (see “M-net trials 500-Gbps via Nokia super coherent Photonic Service Engine 3 with probabilistic constellation shaping”), this is the first conducted over a live production network, the company asserts.
Netia is an alternative operator that operates a more than 50,000-km fiber-optic network that connects more than 80% of the A and B class office buildings in Poland. The filed trial saw wavelengths operating at 62-68 Gbaud driven by the Nokia PSE-3 via the Nokia 1830 Photonic Service Switch transmitted across Netia's flex-grid fiber network in 75-GHz channels. Routes currently supporting 100G and 200G wavelengths transported wavelengths of greater than 300G and 500G, respectively, Nokia says.
"Netia continues to invest in our infrastructure to ensure our customers benefit from the most technologically advanced network in Poland,” said Grzegorz Bartler, member of the board and CTO at Netia. “The results of this field trial mean that our backbone network, originally designed for a total capacity of 8.8 Tbps, now has a proven roadmap to 29 Tbps, ensuring we can continue to keep up with the rapid growth of our business and consumer services."
