RETN deploys 400GbE optics to boost Eurasian network capacity

RETN has completed the large-scale deployment of 400GbE coherent pluggable optics across its entire Pan-Eurasian IP network.

The rollout extends to backbone links ranging from 300 to 950 kilometres. It involves the use of hundreds of 400G pluggable optics, all of which are now live, fully operational, and delivering production traffic across RETN's infrastructure.

The company is presenting this deployment as among the most extensive IP-over-DWDM (IPoDWDM) projects currently in production in the sector. As part of RETN's infrastructure expansion, it emphasises energy efficiency and sustainability metrics.

RETN has stated that it is responding to a forecasted upward trend for coherent pluggable port deployment worldwide. Analysts have suggested that by 2027, over 700,000 coherent pluggable ports will be in use globally, and RETN's programme aligns with these projections, particularly in adopting high-capacity technologies at an early stage.

The company outlined several key efficiency gains from the deployment, including a 40% reduction in power usage, a 55% lower carbon footprint, and a 15% reduction in space requirements within network infrastructure, compared to legacy solutions.

RETN's network currently provides more than 75 Tbit of connectivity for its partners and customers across Eurasia, and company representatives have stated that with the introduction of 400G pluggables, this capacity is set to surpass 100 Tbit in the near future.

Commenting on the development, Tony O'Sullivan, Chief Executive Officer of RETN, said, "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."

The deployment is underpinned by the use of Juniper's current routing platforms, which RETN says have enabled it to implement a standardised and homogeneous infrastructure throughout its network, thus simplifying day-to-day operations and expediting new deployments. RETN reports that this standardised approach reduces operational complexity and has allowed it to pursue a scalable and repeatable expansion model across its Eurasian service area.

RETN's network is constructed on its own uniform DWDM and IP/MPLS Network Platform, supported by land routes extending across Western Europe, Eastern Europe, Central Asia and towards China, with further branching into Southeast Asia. The network is designed to offer short delivery times for telecommunication services, high service availability, and multiple redundancy layers.
