How to choose fiber for MPO/MTP? What is the difference about Several type multimode fiber?
OM4 and OM3 fiber are Gigabit fiber, various performance indexes is better than OM1 and OM2.
| Fiber Type | Core/Cladding (um) | Light Source | Bandwidth @850nm OFL (MHZ·KM) | Bandwidth @850nm EMB (MHZ·KM) | 10Gpbs Ethernet 10G BASE SR/LR | 40Gpbs Ethernet 40G | 100Gpbs Ethernet 100G BASE SR10/IR4 |
| OM1 | 62.5/125 | LED | 200 | Nonsupport | 33M(SR) | Nonsupport | Nonsupport |
| OM2 | 50/125 | LED | 500 | Nonsupport | 82M(SR) | Nonsupport | Nonsupport |
| OM3/150 | 50/125 | VSCEL or LED | 700 | 950 | 150M(SR) | 50M(SR4) | 50M(SR10) |
| OM3/300 | 50/125 | VSCEL or LED | 1500 | 2000 | 300M(SR) | 100M(SR4) | 100M(SR10) |
| OM4 | 50/125 | VSCEL or LED | 3500 | 4700 | 500M(SR) | 150M(SR4) | 150M(SR10) |
OFL= Over Filled Launch; EMB=Effective Modal Bandwidth
