In this video you are given the basics of how Optical Fiber Type affects speed and distance, starting with Multimode 62.5/125 µm (AKA: OM1) and Multimode 50/125 µm core size comes in three different classifications (OM2, OM3 and OM4). Singlemode Fiber is also discussed. These optical fiber types have great differences in their speed and distance.
| Designation | Core/Cladding Diameter (µm) | Type | Gigabit Ethernet Distance (meters) | 10 Gigabit Ethernet Distance (meters) |
|---|---|---|---|---|
| OM1* | 62.5/125 | Multimode | 300 Meters at 850 nm 600 Meters at 1310 nm |
33 Meters at 850 nm 300 Meters at 1310 nm |
| OM2* | 50/125 | Multimode | 600 Meters at 850 nm 600 Meters at 1310 nm |
82 Meters at 850 nm 300 Meters at 1310 nm |
| OM3 | 50/125 | Multimode | 1000 Meters at 850 nm 600 Meters at 1310 nm |
300 Meters at 850 nm 300 Meters at 1310 nm |
| OM4 | 50/125 | Multimode | 1040 Meters at 850 nm 600 Meters at 1310 nm |
550 Meters at 850 nm 300 Meters at 1310 nm |
| ITU-T G.652.D |
9/125 | Singlemode | 5 km at 1310 nm 5 km at 1310 nm |
10 km at 1310 nm 10 km at 1550 nm |
