Fibre Transceivers are modules used in networking devices and Servers for transmitting and receiving optical signals and facilitate communication.
There are both multi-mode and single-mode SFP transceiver types. Single-mode SFP will work with single-mode fiber, while multi-mode SFP will work with multi-mode fibre. More difference between both SM (Single Mode) SFP and MM (Multi-mode) SFP is enlisted below in the table –
SFP Single Mode vs Multimode –
| 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. |
