Cisco SFP-10G-LRM SFP+ Transceiver

The Cisco SFP-10G-LRM SFP+ Transceiver is a high-performance 10 Gigabit Ethernet module engineered for professional networks that demand speed, reliability, and flexible fiber deployment. Built to optimize uplinks, server connections, and data center links, this SFP+ transceiver leverages 1310 nm optics and long-reach multimode fiber (LRM) technology to deliver stable 10G performance over extended MMF links. Compatible with a broad range of Cisco devices and designed for seamless integration, it helps network architects future-proof their infrastructure while minimizing downtime and maintenance complexity. Whether you’re upgrading campus cores, data center interconnects, or enterprise edge services, this module is a trusted choice for delivering consistent throughput, low latency, and efficient bandwidth utilization.

• Blazing fast 10G performance in a compact SFP+ package. This transceiver enables 10 Gigabit Ethernet links with robust stability, ideal for uplinks, server connections, and high-density interconnects. By leveraging 1310 nm optics designed for long-reach multimode fiber, it supports efficient, scalable growth without requiring a full network refresh.
• Broad Cisco compatibility for enterprise-grade reliability. The SFP-10G-LRM is tested and optimized for Cisco switch, router, and line-card ports, ensuring smooth interoperability across Catalyst, Nexus, and other Cisco platforms. With reliable hot-plug operation and predictable behavior, it minimizes integration risk in mission-critical networks.
• Long-reach multimode fiber capability with flexible optics. The module uses Long Reach Multimode (LRM) technology and a duplex LC connector to support extended MMF deployments. This makes it an excellent choice for campuses, building-to-building links, and data centers where legacy MMF is prevalent, allowing you to maximize existing fiber assets.
• Digital monitoring and proactive reliability features. With optional Digital Optical Monitoring (DOM/DDM) support, you can monitor optical power, temperature, supply voltage, and other vital metrics in real time. This visibility helps with proactive maintenance, rapid fault isolation, and improved service levels across your 10G network.
• Easy installation and efficient operation for data-center density. The SFP+ transceiver is hot-swappable and designed for plug-and-play deployment. Its efficient power profile and compact form factor reduce space requirements in dense rack environments, supporting scalable uplinks and simplified cabling in high-performance data centers.

How to Install Cisco SFP-10G-LRM SFP+ Transceiver

To install the Cisco SFP-10G-LRM SFP+ Transceiver correctly and safely, follow these best-practice steps. This ensures optimal performance, reliable links, and minimizes downtime during upgrades or maintenance windows.

• Prepare the device and fibers. Review the device’s maintenance window and ensure you have the correct SFP+ port available. Verify that the fiber cabling is clean, undamaged, and properly terminated for multimode MMF with LC connectors.
• Power considerations and port state. If your network policy requires it, temporarily disable the target port or put the device into a maintenance mode to minimize risk during insertion. In many environments, hot-swapping is supported, but always follow your organization’s change-control procedures.
• Insert the transceiver into the SFP+ slot. Align the module with the slot and push it straight in until the latch engages. Do not torque or bend the fiber cables during insertion, and avoid touching the optical interfaces.
• Connect the fiber link. Attach the duplex LC fiber pair to the transceiver and the corresponding port on the remote device. Ensure transmit and receive fibers are correctly paired to avoid misalignment of signals, which can degrade link performance.
• Enable and test the link. Re-enable the port or device if you disabled it. Use the network management system or CLI to verify link status, speed, and duplex settings. Check for link integrity indicators and, if DOM is supported, review power and temperature readings to confirm healthy operation.
• Validate performance and document. Run baseline throughput and latency tests to confirm the 10G link meets your design expectations. Document the installation for future maintenance and reference, including fiber type, distance, and device port details.
