Fujitsu launched the 1FINITY P300 800G ZR/ZR+ coherent pluggable transceiver, expanding its optical networking portfolio with a high-speed, power-efficient solution. Available globally in the second half of 2025, the P300 supports deployment in third-party routers, Fujitsu’s Edge Networking portfolio, and 1FINITY T-series transponders. The transceiver complies with open optical networking standards, including OIF ZR and Open ROADM MSA, enabling flexible integration across different network architectures.
Built with 3nm digital signal processor (DSP) technology, the P300 delivers a 30% reduction in power consumption per bit compared to previous pluggable generations. The transceiver supports high-speed data center interconnect (DCI), metro, regional, and long-haul transport, addressing increasing bandwidth demands driven by AI and cloud workloads. Fujitsu’s P-series pluggables also offer a future upgrade path to 1.6 terabits per second (Tbps) and beyond. Manufactured in Japan, the transceiver benefits from high-precision engineering and a resilient supply chain.
Fujitsu will showcase the 1FINITY P300 at MWC Barcelona 2025 (March 3-6) and OFC 2025 in San Francisco (April 1-3). The transceiver includes built-in ECC (Error Checking and Correcting) for memory error correction and dual firmware modules for redundancy, ensuring continuous operation. When integrated with the Virtuora Network Control portfolio, it enables streamlined multi-vendor, multi-domain network management, including IP-over-DWDM (IPoDWDM) capabilities. Future updates will expand support for third-party router pluggable management.
