Pluggable PCIe 6.0 Optical Module Targets Data Centers

Kyocera Corporation has developed a new pluggable optoelectronic module supporting the PCIe 6.0 interface for high-performance computing systems. The module, part of the OPTINITY optoelectronic module series, is designed to support optical interconnects between computing components in data center environments.

The device adopts the OSFP-XD pluggable form factor and enables high-capacity optical data transmission between processors, accelerators and other PCIe devices.

Optical PCIe Interconnect for High-Bandwidth Systems
The module supports the PCIe 6.0 x16 communication standard, delivering data rates of 64 gigatransfers per second per lane. Compared with previous electrical PCIe interconnects, the optical transmission approach converts electrical signals from CPUs, GPUs and other processing units into optical signals transmitted through fiber.

Optical interconnects allow higher bandwidth communication while reducing signal degradation over longer distances. The design also eliminates the need for electrical retimers that are typically required in high-speed copper connections.

Removing these retimers can reduce power consumption between PCIe devices, contributing to improved energy efficiency in large-scale data center systems.

Pluggable Architecture for System Integration
Unlike onboard optical modules permanently integrated into system boards, the OSFP-XD design provides a pluggable configuration. This architecture enables easier replacement and system upgrades while offering greater flexibility for data center equipment design.

The module also allows designers to integrate optical PCIe links into existing infrastructure without redesigning entire system architectures.

Extended Connection Distance in Data Centers
Electrical PCIe connections typically support cable lengths of less than 10 meters due to signal integrity constraints. Optical fiber transmission significantly increases the distance between connected devices.

The new module enables connections of several hundred meters or more, allowing flexible placement of servers, accelerators and storage systems within or between racks. This flexibility can improve cooling strategies, system maintainability and infrastructure layout in large computing clusters.

Collaboration and Industry Demonstration
The module was developed in collaboration with AuthenX, a technology company in which Kyocera has invested through its corporate venture capital fund, Kyocera Venture Innovation Fund I.

The product will be exhibited at the Optical Fiber Communication Conference and Exhibition (OFC) 2026 in Los Angeles from March 17 to 19, where Kyocera and AuthenX will present the technology to the optical communications industry.

Expansion of Optical Module Portfolio
Kyocera plans to expand its optoelectronic module lineup beyond the OSFP-XD format. Future developments include modules for additional form factors such as Optical CDFP, targeting different system architectures and high-performance computing applications.

These developments aim to support the increasing bandwidth and scalability requirements of large data center infrastructures and advanced computing systems.
