Intel E25GSFP28SR Ethernet SFP28 Optics Transceiver Module

Intel E25GSFP28SR Ethernet SFP28 Optics Transceiver Module

The Intel E25GSFP28SR is a high‑performance, compact fiber optic transceiver designed for modern data center and enterprise networking environments. It delivers reliable 10 GbE and 25 GbE connectivity over short‑range (SR) links using an 850 nm wavelength.

Key Technical Highlights

• Interface Type: SFP28 – a small form factor pluggable module that supports both 10 GbE and 25 GbE speeds.
• Maximum Data Transfer Rate: 25,000 Mbit/s (25 Gbps) with backward compatibility to 10 Gbps.
• Wavelength: 850 nm – ideal for multimode fiber and short‑reach applications up to 100 m.
• Medium: Glass fiber (LWL) – ensures low attenuation and high bandwidth over optical cabling.
• Power Consumption: 1.2 W, making it energy efficient for dense rack deployments.
• Operating Temperature Range: 0 °C to 70 °C – suitable for typical data center environments.
• Color: Silver – a standard, neutral finish that blends seamlessly with other networking gear.
• RoHS Compliant: Yes – free from hazardous substances such as lead and mercury.

Design & Build Quality

The module features Intel’s proven Ethernet SFP28 Optics series architecture. Its compact dimensions (approximately 110 mm × 59 mm × 18 mm) allow for easy integration into a wide range of chassis and blade systems. The robust metal housing protects the internal optics from environmental stress, while the precision LC connectors ensure reliable signal transmission.

Performance & Compatibility

The E25GSFP28SR supports both 10GBase‑SR and 25GBase‑SR standards, enabling flexible deployment across heterogeneous network fabrics. Its short‑reach capability (up to 100 m on multimode fiber) makes it ideal for intra‑rack or inter‑switch links where high bandwidth is required without the cost of longer reach modules.

Intel’s strict quality control guarantees that each unit meets stringent performance metrics, including:

• Signal Integrity: Low bit error rate (BER) across the specified distance.
• Latency: Minimal propagation delay suitable for latency‑sensitive applications such as high‑frequency trading or real‑time analytics.
• Compatibility: Fully interoperable with Intel Ethernet adapters and a broad range of third‑party switches that support SFP28 interfaces.

Applications & Use Cases

• Data Center Fabric: Connects top‑of‑rack (ToR) switches or blade servers, providing high‑speed uplinks within the same rack or across adjacent racks.
• Enterprise Core Networks: Bridges high‑capacity links between core and aggregation layers where 25 Gbps throughput is essential.
• High‑Performance Computing (HPC): Supports low‑latency, high‑bandwidth interconnects required for scientific simulations or large‑scale data processing.
• Cloud Service Providers: Enables efficient scaling of virtualized environments by delivering consistent 10/25 Gbps connectivity across server farms.

Environmental & Regulatory Compliance

The module is classified under the Export Control Classification Number (ECCN) 5A991, indicating it is subject to U.S. export controls but generally available for commercial use worldwide. Its RoHS compliance ensures that hazardous materials are eliminated, aligning with global environmental standards.

Installation & Maintenance

Installing the E25GSFP28SR is straightforward: insert the LC connector into a compatible SFP28 slot and secure it with the locking mechanism. The module’s low power draw reduces heat generation, simplifying cooling requirements in dense deployments.

Routine maintenance involves visual inspection of the optical connectors for cleanliness and ensuring that the fiber patch cables are properly seated. Intel provides detailed firmware updates and diagnostic tools to monitor module health over time.

Conclusion

The Intel E25GSFP28SR Ethernet SFP28 Optics Transceiver Module delivers a blend of high speed, reliability, and compact design that meets the demanding needs of modern networking infrastructures. Whether you’re building a next‑generation data center, expanding an enterprise backbone, or deploying HPC clusters, this module offers the performance and flexibility required to keep your network running at peak efficiency.
