FS Launches 800G ZR/ZR+ Coherent Optics: High-Capacity, Reliable Connectivity for AI and DCI Networks

NEW CASTLE, Del.--(BUSINESS WIRE)--FS, a trusted provider of ICT products and solutions, has launched its 800G OSFP/QSFP-DD ZR/ZR+ coherent optical module solution, delivering high-capacity optical connectivity for AI scale-across architectures and data center interconnect (DCI) networks. Featuring high transmission rates, high reliability, simplified operations, monitoring visibility, standardized packaging, and interoperability, the solution enables efficient and scalable optical connectivity for AI and cloud deployments.

As AI infrastructure expands beyond a single data center, inter-data-center traffic is growing rapidly, placing greater demands on network bandwidth, fiber efficiency, and operational scalability. To help customers address these evolving requirements, FS has introduced its 800G coherent optical module solution, providing a scalable optical transport platform for AI scale-across and DCI environments.

FS 800G ZR/ZR+ Coherent Modules: Built for High-Capacity and Reliable Optical Networks

FS's 800G ZR/ZR+ coherent optical modules combine high-capacity coherent transmission, carrier-grade reliability, operational visibility, and broad interoperability in a pluggable form factor. Designed for modern optical transport networks, the solution helps customers simplify deployment, improve operational efficiency, and scale network infrastructure with greater flexibility.

High-capacity Coherent Transmission

Powered by a Marvell 5nm DSP and advanced modulation schemes, the modules support up to 800G transmission over distances of 120km and 500km over single-mode fiber, enabling flexible deployment across metro and regional networks.

Efficient Spectrum Utilization

Support for C-band and L-band operation improves fiber resource utilization and increases overall network capacity for AI and cloud traffic.

Carrier-grade Reliability and Interoperability

Compliant with OSFP and QSFP-DD MSA standards as well as 800ZR, OpenZR+, and OIF specifications, the modules ensure broad interoperability across multi-vendor environments. Open FEC further enhances transmission stability and reliability.

Simplified Operations and Visibility

With CMIS and C-CMIS support, the modules enable real-time monitoring, alarm reporting, and streamlined management to reduce operational complexity.

"The growth of AI and DCI traffic is driving greater demand for scalable and efficient optical transport. FS 800G coherent modules are designed to help customers simplify network expansion and scale network capacity more efficiently," said Kyrie Zhang, Senior Technical Director at FS.

The FS 800G coherent optical module solution achieves a balanced combination of performance, efficiency, and interoperability. In future, FS will keep iterating on its products to meet the demands of high‑capacity, DCI, and long‑haul transmission.
