This cutting-edge optical transceiver is designed to meet the demands of modern networks, supporting seamless 10 Gigabit Ethernet links, low latency, and steady performance in extended temperature environments. Engineered by Intel, a trusted name in enterprise-grade hardware, this SFP+ SRX module brings together engineering precision, interoperability, and long-term reliability to ensure your server racks and switching infrastructure stay connected with minimal downtime. Whether you’re upgrading a vendor-neutral fabric or deploying dense top-of-rack connectivity, this optic is built to reduce complexity while maximizing uptime and efficiency across your data center ecosystem.

• High-performance 10GbE connectivity: The SFP+ SRX optics provide reliable 10 Gigabit Ethernet links for uplinks, server connections, and top-of-rack deployments, enabling high-bandwidth data transfer with minimal frame loss and predictable performance under heavy load. The module is designed to optimize signal integrity over typical data center fiber runs, helping maintain consistent throughput for virtualization, flash storage replication, and analytics workloads.
• Extended temperature tolerance: Built for harsh data center environments, these optics operate across an extended temperature range, helping preserve performance in space-constrained or thermally challenging facilities. This resilience reduces the need for expensive cooling upgrades and supports deployments in compact enclosures, edge locations, and non-traditional racks where ambient temperatures can fluctuate.
• MSA-compliant, hot-swappable form factor: The SFP+ module follows the industry-standard MSA footprint, enabling easy installation, quick swaps, and maintenance without downtime or the need for expensive adapters. With hot-swappable capability, you can perform replacements during planned maintenance windows, keeping critical network paths online and reducing mean time to repair (MTTR).
• Digital Diagnostics Monitoring (DDM/DSM): Real-time monitoring of critical parameters such as temperature, supply voltage, TX/RX power, and other health indicators provides proactive insight for proactive maintenance and faster fault isolation. DSM data can be integrated with network management systems to automate alerts, trend analysis, and capacity planning.
• Broad compatibility and energy-efficient operation: Optimized to work with Intel Ethernet adapters and a wide range of 10GBASE-SR capable devices from different vendors, delivering a balance of performance and power efficiency for dense data centers. The optic is designed to minimize idle power and thermal output while delivering stable links, supporting multi-skip, multi-tenant environments and helping reduce total cost of ownership.

how to install Intel® Ethernet SFP+ SRX Optics, Extended Temp

• Power down the host device (server or switch) and locate an available SFP+ slot that matches the module’s form factor and interface requirements.
• Handle the optic with care, avoiding contact with the optical surface. Align the module with the slot and gently insert until the locking mechanism engages securely. Do not force the module; if it does not seat smoothly, remove and reinsert to ensure proper alignment.
• Attach the fiber optic cable to the module’s LC duplex connectors, ensuring the connectors are clean and the polarity is correct. Use a high-quality, policy-appropriate duplex fiber (commonly OM2/OM3 for SRX optics) to maximize link margin and minimize insertion loss.
• Reconnect power and boot the device. Verify link status via the device’s status LEDs and, if available, through your network management system. Use Digital Diagnostics Monitoring (DDM/DSM) data to confirm temperatures and TX/RX power values are within expected ranges.
• Perform a basic connectivity test and a throughput assessment to confirm the link is operational. In dense deployments, monitor for subtle performance variations and verify that the extended temperature capability remains stable under load. Maintain up-to-date firmware and driver compatibility to ensure continued interoperability with the rest of your network stack.
