Description
Why duplex LC is the data-center standard
| Connector Type | What it carries | Where it’s used |
|---|---|---|
| Simplex | One fiber | Pigtails, testing |
| Duplex LC | Two fibers (Tx/Rx) | Switch ↔ Server, Switch ↔ Switch |
A single duplex plug replaces two simplex cords—faster installs, fewer errors, cleaner racks.
Rose-red = high-bandwidth multimode
| Fiber Grade | Color | Typical Reach @ 100G |
|---|---|---|
| OM3 | Aqua | ~70 m |
| OM4 | Rose-red / Violet | ~100 m |
| OM5 | Rose-red / Lime | SWDM-ready |
Using rose-red connectors helps technicians spot OM4/OM5 paths instantly in mixed-fiber environments.
