RETN Completes Pan-Eurasian Deployment of 400GbE Coherent Pluggable Optics

London – May 06, 2025 – RETN, the leading independent global network services provider, has completed the full-scale deployment of 400GbE coherent pluggable optics across its entire Pan-Eurasian IP network, marking one of the most extensive and eco-conscious IP-over-DWDM (IPoDWDM) deployments in production today.


This network-wide rollout places RETN at the forefront of energy-efficient, high-performance networking and reinforces its commitment to sustainable infrastructure growth. Unlike limited-scope trials, RETN’s deployment spans backbone links ranging from 300 to 950 kilometres and involves hundreds of 400G pluggables—all fully operational, stable, and live in production.


With analysts projecting over 700,000 coherent pluggable ports deployed globally by 2027, RETN’s implementation of 400G technology aligns with this shift. But what sets it apart is its early large-scale deployment for high-performance networking while setting new benchmarks for sustainability:


●       40% power savings

●       55% lower carbon footprint

●       15% reduction in space requirements

 

RETN’s network currently delivers over 75 Tbit of connectivity to its partners and customers. The deployment of 400G pluggables will enable RETN to exceed 100 Tbit in the near future.


Tony O’Sullivan, CEO of RETN, stated:

“As demand for high-speed, reliable connectivity continues to grow, RETN remains dedicated to delivering next-generation infrastructure that empowers enterprises, hyperscalers, and carriers worldwide. Our widespread rollout of 400G services, powered by Juniper’s latest routing platforms, positions us at the forefront of ultra-high-capacity, sustainable networking. We're also actively evaluating 800G technology to ensure our network remains future-ready.”


RETN leverages Juniper's advanced equipment to create a standardised, homogeneous infrastructure that simplifies operations and accelerates deployments. This collaboration reduces complexity, ensures consistent performance, and enables RETN to expand its Eurasian footprint with a scalable, repeatable model.
