Description
Color-coded multimode makes networks easier to manage
| Jacket color | What it usually represents |
|---|---|
| Yellow | Single-mode |
| Orange | OM1 / OM2 multimode |
| Lake Blue (Aqua) | OM3 / OM4 high-speed multimode |
This visual standard is widely used in data centers, cloud facilities and telecom rooms.
3.0mm duplex — built for structured cabling
| Cable size | Typical role |
|---|---|
| 2.0mm | Patch cords at switch ports |
| 3.0mm | Racks, cable trays, cabinet-to-cabinet links |
The thicker jacket protects multimode fibers from bending loss and physical stress when routed through dense cabling paths.
Multimode optical performance
| Parameter | Typical value |
|---|---|
| Fiber type | OM3 / OM4 |
| Core size | 50/125 µm |
| End face | UPC |
| Insertion loss | ≤ 0.30 dB |
| Return loss | ≥ 35 dB |
| Wavelengths | 850 / 1300 nm |
| Mating life | ≥ 1000 cycles |
These characteristics support 10G, 40G and 100G Ethernet inside data centers and enterprise networks.
Duplex LC construction
| Component | Purpose |
|---|---|
| 1.25mm ceramic ferrules | Precise multimode alignment |
| UPC polished end faces | Stable optical coupling |
| Duplex LC clip | Maintains Tx/Rx pairing |
| 3.0mm lake-blue jacket | High visibility & protection |
Professional Q&A
Does the lake-blue color affect performance?
No. The color is for identification and management only. Optical performance is defined by the fiber and polish.
Is this compatible with OM3 and OM4 transceivers?
Yes. It is designed specifically for high-speed multimode systems.
Can this be used in LC patch panels?
Yes. The LC interface is standard and fits all LC UPC adapters.
