Cisco 10GbE SFP+ Transceiver Module 10GBase-LR

The Cisco SFP-10G-LR++= is a hot-swappable SFP+ transceiver module that lets your Cisco switch, router, or server move 10 Gigabit Ethernet traffic across single-mode fiber for distances up to 6.2 miles or 10 kilometers. It operates at the 1310 nm wavelength and mates with standard LC connectors, so it fits smoothly into existing fiber runs without special cabling.

This module is a practical choice for network administrators who need to extend high-bandwidth links between campus buildings, connect data center racks, or tie remote aggregation points back to a core switch. Installation takes only a few seconds: slide the module into an open SFP+ slot, connect the LC fiber pair, and the link comes up immediately with no additional configuration. Because it is qualified for the Cisco 250 Series, Catalyst ESS9300, Nexus, and UCS platforms, you can standardize on a single optic across access, aggregation, and compute layers, simplifying spares management and support contracts.

In everyday use, the Cisco SFP-10G-LR++= helps keep latency low and bandwidth consistent, which is important for storage replication, high-definition video distribution, and large data transfers between servers. Its long reach makes it valuable when copper cabling or short-range optics cannot span the required distance, letting you scale your network without signal repeaters or extra hardware.
