Product Description
The Dell SFP28-25G-SR transceiver is a high-performance optical module engineered to meet the growing demands for bandwidth in modern data centers. Operating at 25Gbps, it provides a significant upgrade over previous generations of 10Gbps interfaces, enabling faster server connectivity, improved East-West traffic flow, and enhanced performance for demanding applications like AI/ML workloads and high-performance computing. The SFP28 form factor ensures compatibility with a wide range of Dell switches and servers, as well as other network devices that support this standard. This transceiver utilizes the 850nm wavelength, which is standard for short-reach optical communication over Multi-Mode Fiber (MMF). MMF is a cost-effective cabling solution for intra-data center distances, and the SR (Short Reach) designation indicates its suitability for links typically up to 100 meters when used with OM4 fiber. The module features a standard LC duplex connector, providing a secure and reliable physical interface for the fiber optic cable. Its hot-pluggable nature allows for easy installation and replacement without the need to power down the connected equipment, minimizing network downtime. The SFP28-25G-SR is specifically optimized for use within Dell's networking ecosystem, ensuring seamless integration and reliable performance. It is an essential component for network architects looking to build scalable, high-performance networks that can support the increasing demands of cloud computing, big data analytics, and virtualization. By providing a robust 25Gbps connection, this transceiver helps to eliminate network bottlenecks and improve overall application responsiveness.
