Open XR Forum Successfully Completes Record-breaking Point-to-Point Trial of 400G Pluggable Optics

San Jose, Calif. – March 7, 2023 – The Open XR Forum announced today the successful demonstration of long-haul point-to-point transmission between QSFP56-DD coherent transceivers over 1,400 km at 400 Gb/s using 16QAM modulation, as well as error-free performance at 300 Gb/s using 8QAM modulation over a span of 2,495 km. In addition to demonstrating long-reach performance equal to or greater than current state-of-the-art transceivers, this is the first published demonstration of an advanced management method that enables management and control of optical transceiver functions independently from the host equipment.

The details and results of this demonstration are available in an Open XR Forum report, P2P (Point-to-Point) Performance and Host Independent Management Proof of Concept Demonstration. The testing was conducted in conjunction with founding member Lumen Technologies using Infinera’s ICE-XR 400G QSFP56-DD transceivers operating in third-party routers and transmitting over third-party line systems. The long-distance performance demonstrates the potential for pluggable transceivers to be used in DWDM long-haul and large metro networks. The integrated management features, which included in-band remote management and streaming telemetry, demonstrated transport functionality typically found in a transponder, but in the compact form of a pluggable transceiver. This management decoupling of key transceiver functions from host routing functions is a new and easily generalized method for integration and management of coherent transceivers in any host device, including routers, switches, and servers. The ability to separate management of IP and Optical functions better aligns with existing service provider operational models, helping resolve a key barrier for deployment of IP over DWDM.

About Open XR Forum

Open XR Forum was founded to foster collaboration between its members to facilitate the adoption and accelerate the growth of network architectures leveraging intelligent point-to-point and point-to-multipoint coherent pluggable transceivers. Members will work to ensure the products and services developed align with existing standards and operational models by driving the standardization of network interfaces and electro-mechanical hardware interfaces, demonstrating interoperability, establishing multi-sourcing potential, and developing and publishing new specifications as needed. This will accelerate the wide adoption and deployment of XR optics’ innovative technology by a broad spectrum of network operators in a wide variety of applications. Open XR Forum membership is intended for network operators, network equipment vendors, and component suppliers. For more information, visit
