How to determine single-mode or dual-mode optical modules

How to determine single-mode or dual-mode optical modules

To identify whether your SFP module is single-mode or multimode, follow these steps: The easiest way to determine the type of your SFP module is by checking the label or the product's specifications. Manufacturers will typically mark the module with "SM" for single-mode and "MM" for. They might look almost identical from the outside, but knowing the difference is important. The distinction is important as it affects network performance, distance, and overall cost. Single-Mode (SM) Modules: These have a smaller core diameter, typically around 9 micrometers.
