Single mode and multimode optic fibers, or SFP modules, are developed with incompatible structure and light transmission properties. What are the maximum distances of SX vs. Short answer: No. These differences determine which transceivers work with which fiber and how far signals can travel. They are easier to set up and give steady communication. Conclusion: Multimode is short-distance & cost-efficient. Single-mode is. Can single mode and multimode fibers or modules be mixed? What are the maximum distances of SX vs LX modules? How can I identify the fiber type installed? How do the costs of multimode compare to single mode SFP modules? Which has a larger impact on SFP module performance for an optical network:. Single mode fiber has a very narrow core (around 8–10 microns in diameter), so it only allows one light signal (or "mode") to pass through at a time. It allows just one light signal – typically lasers – to pass through at a time. We can see that they cannot be mixed.
