Description
Why choose 3.0mm for multimode jumpers
| Cable Diameter | Durability | Typical Environment |
|---|---|---|
| 0.9mm | Low | Pigtails, splicing |
| 2.0mm | Medium | Standard patch cords |
| 3.0mm | High | High-traffic racks, industrial sites |
The thicker jacket protects fibers from bending, vibration, and accidental pulling.
Multimode optical performance
| Parameter | Typical Value |
|---|---|
| Fiber Type | Multimode OM2 / OM3 / OM4 / OM5 |
| Core / Cladding | 50 / 125 µm or 62.5 / 125 µm |
| Polish Type | UPC |
| Insertion Loss | ≤ 0.30 dB |
| Return Loss | ≥ 35 dB |
| Wavelengths | 850 / 1300 nm |
| Supported Data Rates | 10G / 25G / 40G / 100G (short reach) |
| Durability | ≥ 1000 mating cycles |
These specs ensure reliable signal quality even in demanding environments.
Mechanical construction
| Feature | Specification |
|---|---|
| Connector Type | LC Simplex |
| Cable Diameter | 3.0mm |
| Ferrule | 1.25mm zirconia ceramic |
| Boot | Long, reinforced strain relief |
| Latching System | LC push-pull |
| Operating Temperature | –40°C to +75°C |
| Tensile Strength | ≥ 120 N |
The reinforced boot and thick jacket prevent micro-bending and mechanical stress that can degrade multimode signals.
