Single Mode SFP vs Multimode SFP

Rashmi Bhardwaj | Blog,Hardware, Infrastructure & Design

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 –

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
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.
