What is the minimum distance on SFP 10G LR?
Knowledge Base + 2024.01.08

SFP (Small Form-factor Pluggable) 10G LR (Long Range) is an optical transceiver module designed for 10 Gigabit Ethernet (10GbE) applications over single-mode fiber optic cables. The "LR" designation implies that the module is intended for long-range connections. However, it's important to note that the minimum and maximum distances supported by an SFP 10G LR module can vary depending on the specific product and the optical characteristics of the fiber optic cable used.

As of my last knowledge update in January 2022, the typical minimum distance for SFP 10G LR modules is around 2 meters. This means that the module is designed to work effectively for connections with distances greater than 2 meters. However, it's crucial to refer to the product documentation provided by the module manufacturer for precise information on the minimum supported distance.

When working with optical transceivers, the actual performance can be influenced by factors such as the quality of the fiber optic cable, the presence of splices or connectors, and the environmental conditions. Therefore, it's advisable to follow the guidelines and specifications provided by the manufacturer to ensure reliable and optimal performance in your specific network setup.

For the latest and most accurate information on the minimum distance of a particular SFP 10G LR module, please refer to the product datasheet, technical specifications, or contact the manufacturer or supplier directly.
