No, single-mode SFPs are designed to work with single-mode fiber cables and multimode SFPs are designed to work with multimode fiber cables. Attempting to use a single-mode SFP with a multimode fiber cable could result in poor network performance or data transmission errors. It utilizes ultra-low optical attenuation for medium to long transmission. The single mode SFP generally uses high-cost FP and DFB lasers with long wavelengths to optimize.
