What is the maximum cable length for 10GBASE-LR?

10GBASE-LR is a standard for 10 Gigabit Ethernet over single-mode fiber optic cables. The "LR" stands for "Long Reach," indicating that this particular standard is designed for longer distances compared to some other 10GBASE specifications. The maximum cable length for 10GBASE-LR is indeed 10 kilometers, which allows it to establish connections across significant distances in network infrastructure.

This capability makes 10GBASE-LR suitable for applications where devices might be located far apart, such as in large data centers or between buildings on a campus. The use of single-mode fiber ensures low signal attenuation over these longer distances, facilitating efficient data transmission with minimal loss. Understanding the maximum distances and appropriate cabling standards is crucial for network design and implementation because it impacts the overall architecture and performance of the network.
