This plug-in SFP28 module supports both 10GBase-SR and 25GBase-SR, enabling seamless upgrades from 10G to 25G without replacing your existing optics or switching hardware. Designed to work across Lenovo ThinkSystem servers, switches, and compatible SFP28-enabled devices, this transceiver provides a reliable, hot-pluggable solution for dense rack deployments, virtualization workloads, and high-speed storage networks. With an industrial-grade 85°C rating, it is built to endure demanding data-center environments while maintaining optimal performance and link integrity. Whether you are building a new data fabric, expanding a storage-area network, or refreshing legacy infrastructure, this transceiver offers consistent, scalable bandwidth with minimal disruption.

• Flexible dual-rate performance for future-proof networking. This SFP28 transceiver supports both 10GBase-SR and 25GBase-SR, enabling smooth migration paths from legacy 10G links to 25G high-speed connections. Designed for short-reach fiber links, it delivers robust performance across a wide range of data-center scenarios—from rack-to-rack interconnects to top-of-rack and spine-leaf architectures. The dual-rate capability reduces procurement complexity and lets you standardize on a single optic family while still meeting immediate needs and long-term scalability. It is ideal for hyperscale deployments, a campus-style network, or enterprise environments that require agile bandwidth provisioning without the overhead of replacing existing cabling runs.
• Industrial-grade reliability with an 85°C rating for demanding environments. The transceiver is engineered to operate reliably in challenging data-center conditions, including high-density racks, continuous workloads, and variable cooling scenarios. The 85°C temperature rating extends device life and reduces the risk of thermal throttling or failure in hot-aisle environments. With strict manufacturing quality and RoHS compliance, this module maintains stable performance over time, preserving link budgets and minimizing downtime—critical factors for service-level agreements and customer satisfaction.
• High-bandwidth SR optics optimized for multimode fiber. The 850 nm short-reach (SR) optical technology is tailored for multimode fiber installations, delivering low-latency, high-bandwidth links within a data center. By leveraging 25GBASE-SR for high-speed server-to-switch communications and 10GBASE-SR where applicable, you gain substantial throughput without sacrificing compatibility. The module typically supports MMF fiber types (such as OM3/OM4) with LC duplex connectors, making it compatible with standard, widely deployed fiber infrastructures. This enables dense deployment of high-performance workloads, virtualization tasks, and data-intensive applications while maintaining cost-effective cabling strategies.
• Plug-and-play installation with seamless device compatibility. The SFP28 form factor is designed for effortless hot-swapping in SFP28-enabled switches and servers. No additional cables or complex configurations are required for basic operation—connect the fiber link and power on your devices, then use your switch or server management interface to enable the desired speed. The module is compatible with Lenovo ThinkSystem servers and other SFP28-capable devices, ensuring broad interoperability across your vendor ecosystem. This plug-and-play nature reduces maintenance time, accelerates deployment, and minimizes the risk of configuration errors during upgrades or migrations.
• Energy-efficient design to lower total cost of ownership. In addition to high performance, the transceiver emphasizes power efficiency to help reduce cooling requirements and energy costs in dense data-center environments. By delivering the necessary bandwidth with a compact, low-power footprint, this module supports higher port density without dramatically increasing heat output. For operators seeking sustainable, cost-conscious networking solutions, the Lenovo Dual Rate SFP28 transceiver offers a compelling balance of speed, reliability, and efficiency.
