Cisco SFP28 Module

The Cisco SFP28 Module—the high-density, low-power 25GBASE SFP28 transceiver family designed for data centers, cloud deployments, and high-performance computing networks. Built to fit Cisco's server-to-network ecosystem, these transceivers enable scalable 25 gigabit Ethernet connectivity across server, storage, and switch fabrics. The SFP28 form factor keeps airflow and rack space optimized while delivering the performance required by modern workloads, from virtualization and containerized apps to AI inference pipelines and large-scale HPC workloads. With a focus on interoperability, Cisco guarantees compatibility with Cisco Nexus switches, Cisco UCS servers, and a broad array of Cisco-compatible equipment, ensuring a smooth migration path from 10G and earlier generations. The modules are engineered for reliability with robust features that reduce error rates and increase link stability. For data centers seeking energy efficiency, Cisco's 25G SFP28 portfolio is optimized for reduced per-port power consumption, contributing to lower cooling costs, improved PUE, and a smaller carbon footprint, all while delivering the bandwidth required by today’s workloads. Whether consolidating existing networks or building new fabrics, these transceivers offer flexible reach options and fiber compatibility to fit a variety of deployment scenarios, and they are designed for hot-swappable operation in supported Cisco devices to minimize downtime during maintenance windows. Cisco's SFP28 modules deliver predictable performance, broad vendor support, and long product lifecycles, ensuring your investment remains future-proof as networks scale to 25G and beyond.

• High-density 25GBASE SFP28 modules enable scalable, high-throughput connectivity in data centers and HPC environments, allowing you to maximize uplink capacity while minimizing port sprawl and rack space. These transceivers help you accelerate workloads, reduce latency, and support more virtual machines, containers, and storage traffic on a single fabric.
• Versatile configurations and reach options across fiber types give you flexible deployment paths. Depending on SKU, you can select variants optimized for short-reach intra-data-center links or longer-reach interconnections, ensuring you get the right balance of distance, performance, and cost for your network.
• Low power consumption per port contributes to greener data centers by reducing cooling requirements and energy costs. The 25G SFP28 family is designed to deliver strong performance per watt, helping you achieve a favorable total cost of ownership over the life of the hardware.
• Hot-swappable, plug-and-play operation integrates smoothly with Cisco ecosystems. These modules are designed to drop into supported Cisco switches, routers, and servers with minimal downtime, enabling rapid rack-scale upgrades and seamless capacity expansion.
• Backed by Cisco’s reliability and warranty programs, the SFP28 modules offer interoperability across Cisco data-center gear and enterprise-grade support. This ensures a consistent experience across your Cisco-backed network fabric and reduces maintenance risk during upgrades.

How to install Cisco SFP28 Module

• Verify that the chosen SFP28 module SKU matches your Cisco device’s requirements (reach, fiber type, and wavelength) to ensure proper interoperability.
• If required by your maintenance policy or chassis, power down the device or confirm hot-swap capability before installation.
• Remove the protective dust cap from the SFP28 module and inspect the connector for any debris or damage.
• Align the module with the SFP28 slot and insert it straight into the slot until it seats securely with a definitive click.
• Attach the corresponding fiber optic cable to the module, ensuring the connector is clean and the fiber bend radius is respected to avoid signal loss.
• Power up the device (if it was powered down) and verify link status through the device LEDs or management software, then run basic connectivity tests to confirm proper operation.
