Open XR Optics Forum has expanded its transceiver specification framework to include 100G modules and single-fiber bi-directional applications, extending the reach of coherent pluggable technology across a wider set of network scenarios. The update builds on the Forum’s existing 400G XR Optics specifications and is aimed at making coherent point-to-point and point-to-multipoint architectures more cost-effective and flexible for access, aggregation, and transport networks.
The newly added 100G interfaces support three application modes: single-fiber bi-directional point-to-point links for compact deployments, dual-fiber point-to-multipoint aggregation for ROADM-based and regional networks, and single-fiber bi-directional point-to-multipoint overlays designed to coexist with legacy PON deployments. By integrating these new specifications into the framework, operators can scale bandwidth more efficiently without the need for disruptive infrastructure overhauls.
The updated specifications will be showcased during ECOC 2025 in Copenhagen, at the Open XR Optics Forum Symposium on September 30. The session will highlight technical details, deployment experiences, interoperability results, and the roadmap for future coherent pluggable innovations.
• 100G coherent single-fiber bi-directional point-to-point
• 100G coherent dual-fiber point-to-multipoint aggregation
• 100G coherent single-fiber bi-directional PON overlay
• Complements existing 400G XR Optics specifications
• Designed for access, metro, and regional transport applications
“By extending XR Optics to 100G coherent modules and bi-directional capabilities, we are making coherent pluggable technology accessible to an even broader set of operator environments,” said the Open XR Optics Forum.
🌐 Analysis: The expansion to 100G modules positions the Forum to address operator needs beyond high-capacity metro and core deployments, opening coherent pluggables to access and aggregation layers where cost and fiber availability are critical factors. This move mirrors similar trends in the industry, where vendors such as Ciena, Infinera, and Acacia (Cisco) have been advancing compact coherent solutions to support 100G and 400G use cases in converged access networks.
