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.
