Description
Why OM3 still dominates enterprise fiber
| Fiber Grade | Couleur | Typical Data Rate |
|---|---|---|
| OM2 | Orange | 1G–10G |
| OM3 | Aqua Green | 10G–100G (short reach) |
| OM4 | Rose-red / violet | Higher distance at 40G/100G |
| OM5 | Lime green | SWDM & advanced links |
OM3 is widely used because it provides excellent performance with lower cost than OM4 or OM5.
Performances optiques
| Paramètres | Valeur typique |
|---|---|
| Type de fibre | Multimode OM3 (50/125 µm) |
| Type de polissage | CUP |
| Perte d'insertion | ≤ 0,30 dB |
| Perte de retour | ≥ 35 dB |
| Longueurs d'onde | 850 nm / 1300 nm |
| Largeur de bande modale | Optimized for high-speed LAN |
| Durabilité | ≥ 1000 cycles d'accouplement |
This performance easily supports 10G, 40G and short-reach 100G Ethernet.

Questions et réponses professionnelles
Q1: What does aqua green indicate?
Aqua green is the international color for OM3 multimode fiber, used for 10G to 100G short-reach links.
Q2: Can OM3 LC connectors be used in OM4 systems?
Yes. OM3 connectors are fully compatible with OM4 fiber; OM4 simply offers longer distance and higher bandwidth.
Q3: Why use 0.9mm instead of 2.0mm?
0.9mm connectors are used for pigtails and internal fiber routing, while 2.0mm is used for patch cords.
