Physical Difference
Physical difference mainly lies in diameter, jacket color, optical source and bandwidth, which is described in the following table.
| MMF Cable Type | Diameter | Jacket Color | Optical Source | Bandwidth |
|---|---|---|---|---|
| OM1 | 62.5/125µm | Orange | LED | 200MHz*km |
| OM2 | 50/125µm | Orange | LED | 500MHz*km |
| OM3 | 50/125µm | Aqua | VSCEL | 2000MHz*km |
| OM4 | 50/125µm | Aqua | VSCEL | 4700MHz*km |
| OM5 | 50/125µm | Lime Green | VSCEL | 28000MHz*km |
Practical Difference
Multimode fibers are able to transmit different distance ranges at various data rate. You can choose the most suited one according to your actual application. The max multimode fiber distance comparison at different data rate is specified below.
| MMF Category | Fast Ethernet | 1GbE | 10GbE | 40GbE | 100GbE |
|---|---|---|---|---|---|
| OM1 | 2000m | 275m | 33m | / | / |
| OM2 | 2000m | 550m | 82m | / | / |
| OM3 | 2000m | / | 300m | 100m | 70m |
| OM4 | 2000m | / | 550m | 150m | 150m |
| OM5 | / | / | 550m | 150m | 150m |
