Difference between Single Mode Vs Multimode FO cable
| Sr no | Single Mode FO Cable | Multimode FO Cable |
|---|---|---|
| 1 | Light Carrying core is smaller in diameter , typically between 8.3 to 10 Micrometre | Light Carrying core is larger in diameter , typically between 50 to 100 Micrometre |
| 2 | only one mode will propagate typically 1310 or 1550nm | Light waves are dispersed into numerous paths, or modes, typically 850 or 1300nm |
| 3 | Gives highest transmission speed & less signal distortion | Multimode fibre gives you high bandwidth at high speeds over short distances |
| 4 | Due to high cost of transceiver, single mode FO cable is far more expensive than multimode FO cable | Multimode FO cables are relative cheaper |
| 5 | Suitable for long distance application | Can be used for short/medium distance application |
| 6 | It uses laser diode based fibre optic transmission equipment which is main reason for high cost | It uses LED based fibre optic equipment |
| 7 | Maximum length varies from 5 km to 40 km based on bandwidth | It is recommended for Fibber run less than 400 m |
| 8 | Govern by ITU G.652 standard | Govern by ITU G.651 standard |
