Why 3.0mm matters in multimode cabling
| Cable diameter | Practical use |
|---|---|
| 2.0mm | Switch and transceiver ports |
| 3.0mm | Racks, trays, cabinet-to-cabinet links |
The heavier jacket protects the OM fiber from bending loss and crushing in crowded cable pathways.
Multimode optical behavior
| Parametre | Tipik değer |
|---|---|
| Fiber tipi | OM2 / OM3 / OM4 |
| Çekirdek boyutu | 50/125 µm or 62.5/125 µm |
| Uç yüz | UPC |
| Ekleme kaybı | ≤ 0,30 dB |
| Geri dönüş kaybı | ≥ 35 dB |
| Dalga Boyları | 850 / 1300 nm |
| Çiftleşme hayatı | ≥ 1000 döngü |
These values support Ethernet, SAN and high-speed optical interconnects inside buildings and data halls.
Duplex LC design
Two fibers are held in one LC duplex housing, ensuring stable polarity and synchronized transmit/receive paths even during maintenance.
| Element | Function |
|---|---|
| 1,25 mm seramik yüksükler | Precise fiber alignment |
| UPC polish | Low reflection for multimode lasers |
| Çift yönlü LC klips | Locks Tx/Rx together |
| Thick 3.0mm jacket | Protects against bending and tension |
Profesyonel Soru-Cevap
Is 3.0mm too stiff for LC connectors?
No. The LC ferrule and housing are standard. Only the cable is thicker, providing better protection for backbone routes.
Can this be used with OM3 and OM4 fiber?
Yes. It is fully compatible with OM2, OM3 and OM4 multimode fiber.
Should I use APC for multimode links?
No. Multimode systems use UPC. APC is designed for single-mode reflection control.
