Nokia introduced new high-capacity shelves for its 1830 Photonic Service Switch (PSS) portfolio, designed to help operators scale optical networks to meet accelerating bandwidth demand from AI, cloud, video, and mobile traffic. The new 1830 PSS-HC shelves deliver up to three times higher density and reduce power consumption per bit by as much as 60%, enabling operators to expand capacity while lowering operational costs.
The two new systems, PSS-10hc and PSS-4hc, integrate seamlessly with existing 1830 PSS deployments and maintain full compatibility with the platform’s operational framework. Each shelf supports as much as 12 Tbps per slot, offering a scalable path for service providers as they adopt the latest generations of coherent optical engines. The new shelves feature enhanced thermal efficiency through front-to-back airflow and advanced power management for dense photonic deployments.
Nokia said the 1830 PSS-HC series, part of one of the world’s most widely deployed optical transport platforms, will be available commercially in Q2 2026. “In the era of AI, operators need to scale bandwidth faster and more cost-effectively than ever,” said Ron Johnson, Senior Vice President and General Manager of Optical Networks at Nokia. “The 1830 PSS-HC shelves represent an important evolution of the 1830 PSS family, combining ultra-high density with greater capacity and the PSS rich set of carrier-grade features.”
• PSS-HC shelves improve network density by 3× and cut power per bit up to 60%
• Seamless integration with existing 1830 PSS deployments
• Up to 12 Tbps per slot to support new coherent optical engines
• Enhanced thermal design with front-to-back airflow and power efficiency
• Commercial availability scheduled for Q2 2026
🌐 Analysis: Nokia’s optical networking roadmap continues to focus on scalable photonic architectures built around the 1830 PSS platform, which already anchors transport networks for many Tier-1 operators.
