Description
Why 2.0mm is the standard for LC patch cords
| Cable Diameter | Typical Role |
|---|---|
| 0.9mm | Pigtails, internal fiber |
| 2.0mm | LC patch cords & jumpers |
| 3.0mm | Outdoor & rugged cords |
The 2.0mm cable offers the best balance between flexibility and tensile strength, making it ideal for indoor fiber routing.
Optical performance
| Parameter | Typical Value |
|---|---|
| Fiber Type | Single-mode 9/125 µm |
| Polish Type | UPC |
| Insertion Loss | ≤ 0.30 dB |
| Return Loss | ≥ 50 dB |
| Wavelengths | 1310 / 1550 nm |
| Repeatability | ≤ 0.1 dB |
| Mating Durability | ≥ 1000 cycles |
This performance supports FTTH, telecom backbone and data transmission links.
Mechanical structure
| Feature | Specification |
|---|---|
| Connector Type | LC Simplex |
| Cable Diameter | 2.0mm |
| Ferrule | 1.25mm zirconia ceramic |
| Boot | Standard strain-relief boot |
| Latching System | LC push-pull |
| Operating Temperature | –40°C to +75°C |
| Tensile Strength | ≥ 100 N |
The reinforced boot and jacket protect the fiber from bending and pulling during daily operation.
