2024.01.05It depends on the specific application and requirements. Multimode fiber typically has a larger core size and can carry multiple modes of light, making it suitable for shorter-distance transmissions. Single-mode fiber, on the other hand, has a smaller core size and can carry a single mode of light, making it more suitable for longer-distance transmissions.
In general, single-mode fiber provides higher bandwidth and longer transmission distances, making it more suitable for long-haul and high-speed data transmission, while multimode fiber is often used for shorter distances, such as within buildings or campus networks.
Therefore, neither multimode nor single-mode can be considered inherently "better" than the other, as their suitability depends on the specific needs of the application.
| PARAMETER | SM SFP | MM SFP |
|---|---|---|
| Abbreviation for | Single Mode SFP | Multimode SFP |
| Distance Supported | Can Support Greater distance than MM Fiber. SM Fiber can support distance value as high as 80 km or even 120 km | Used for short distance transmission reaching 100 m and 500 m |
| Cost | SM SFP is costly | MM SFP is cheaper than SM SFP |
| Core Size | Single-mode fiber has a smaller core (9 micron) | Multi-mode fiber has a broader core (62.5 and 50 micron) |
| Wavelength supported | works mainly in 1310nm and 1550nm wavelength | Works mainly in 850nm wavelength |
| Preferential usage | Used inside LAN for Switch ,Router and Server connectivity inside Building or Data Center | Required on WAN connectivity like Service provider Handoff to office/Data Center or connectivity between offices. |
| Colour schema | The colour coded bale clasp and colour arrow on label are generally blue, yellow or purple. And the colour of compatible fiber optic patch cord is yellow. | Their colour coded bale clasp and colour arrow on label are black and the used fiber optic patch cord is usually orange. |
