Cisco SFP-10G-LR Cisco 10gb Sfp+ Lr Module, Smf

The Cisco SFP-10G-LR is a high-performance SFP+ (Small Form-Factor Pluggable Plus) transceiver module, specifically engineered for 10 Gigabit Ethernet (10GbE) applications. Crucially, the “LR” in its designation stands for “Long Reach,” indicating its capability to transmit 10GbE data over significant distances using single-mode fiber optic cable. In essence, this module is a cornerstone for building robust and scalable data center, enterprise, and service provider networks that require high bandwidth over extended links.

Core Specifications and Capabilities:

• 1310 nm Wavelength: The module transmits and receives optical signals at a wavelength of 1310 nanometers.
• Like many advanced Cisco transceivers, the SFP-10G-LR supports Digital Optical Monitoring (DOM), also known as Digital Diagnostics Monitoring (DDM). DOM is instrumental for proactive troubleshooting, performance monitoring, and ensuring the health and stability of the optical link.
• The SFP-10G-LR is fully compliant with the IEEE 802.3ae 10GBASE-LR standard, ensuring interoperability with other compliant 10GbE equipment. It also adheres to the SFP+ Multi-Source Agreement (MSA), which guarantees compatibility across various vendor platforms supporting SFP+ modules.

Typical Applications:

Given its long-reach capabilities, the Cisco SFP-10G-LR is commonly employed in:

• Connecting core switches and routers in large enterprise networks.
• Building metropolitan area networks (MANs) or campus networks spanning several kilometers.
• Providing 10GbE uplink connections from aggregation layers to core layers.

Ultimately, the Cisco SFP-10G-LR stands out as a reliable, high-performance solution for extending 10 Gigabit Ethernet connectivity over substantial distances using single-mode fiber, with the added benefit of real-time performance monitoring.
