Design and Build Quality

The Intel SFP+ SR module features a robust aluminium enclosure that shields sensitive optical components from mechanical shock and electromagnetic interference. The LC connector is engineered for secure, low‑loss attachment to multimode fiber cables, ensuring consistent signal integrity across the 300 m reach.

Internally, the transceiver houses precision laser diodes and photodiodes calibrated for 850 nm operation. These components are mounted on a thermally stable substrate that maintains performance within the specified temperature range of 0–70 °C. The low power draw of just 1 W minimizes heat generation, allowing the module to operate reliably in densely populated racks without additional cooling requirements.

Performance Characteristics

The Intel SFP+ SR optics deliver a clean, high‑speed data stream at 10 Gbps. Its short‑reach design is optimized for intra‑data‑center links, where distances rarely exceed 300 m. The module’s optical output power and sensitivity are calibrated to meet the stringent requirements of multimode fiber standards (OM3/OM4), providing robust performance even in environments with multiple splices or connectors.

Because it operates at a fixed wavelength of 850 nm, the transceiver is compatible with standard multimode fiber infrastructure. This compatibility simplifies deployment and reduces the need for specialized cabling solutions, making the module an attractive choice for organizations looking to upgrade existing fiber networks to 10 Gbps speeds.

Applications and Use Cases

• Data Center Interconnect: Ideal for connecting switches, routers, and servers within a rack or across adjacent racks where short‑range optical links are required.
• Enterprise LAN Expansion: Provides high‑bandwidth connectivity between floor‑level switches in office buildings.
• Supports the demanding data rates needed for HPC clusters and storage arrays.
• Suitable for short‑haul links within telecom infrastructure where 10 Gbps throughput is essential.
• Reliable, low‑power operation makes it suitable for industrial networking environments that require robust optical connectivity.

Installation and Compatibility

The Intel SFP+ SR module follows the standard hot‑swap protocol of SFP+ transceivers. It can be inserted or removed from compatible switch, router, or server ports without powering down the host device, minimizing downtime during upgrades or maintenance.

Because it is an optical transceiver, the module requires multimode fiber (OM3/OM4) with LC connectors for full performance. When paired with compatible SFP+ hosts that support 10 Gbps Ethernet, the module delivers seamless integration and straightforward management through standard network device interfaces.

Environmental and Regulatory Compliance

The module’s RoHS compliance ensures it contains no hazardous substances such as lead, mercury, or cadmium. This certification aligns with global environmental regulations and supports responsible e‑waste management practices.

Additionally, the product’s ECCN of 5A991 indicates that it is subject to U.S. export controls for dual‑use technology. While this classification does not restrict domestic use, it ensures compliance with international trade regulations when shipping across borders.

Longevity and Reliability

With a launch date of Q4 2009, the Intel SFP+ SR optics module has been field‑tested for over a decade. Its proven track record in high‑density networking environments speaks to its durability and reliability. The low power consumption and robust aluminium housing contribute to extended operational life, reducing the need for frequent replacements.

Conclusion

The Intel Network Connectivity Ethernet SFP+ SR Optics Module is a compact, high‑performance solution for 10 Gbps short‑reach optical networking. Its combination of low power consumption, robust build quality, and strict compliance with environmental standards makes it an ideal choice for data centers, enterprise LANs, and industrial applications that demand reliable, high‑speed connectivity over multimode fiber.
