Why 3.0mm matters in access networks
| Cable Diameter | Mechanical Benefit | Typical Use |
|---|---|---|
| 0.9mm | Lightweight | Internal pigtails |
| 2.0mm | Flexible & strong | Indoor FTTH cords |
| 3.0mm | High tensile & crush resistance | Outdoor & industrial fiber links |
The 3.0mm design protects fibers from installation stress, accidental pulling, and vibration in field deployments.
Optical performance
| Parameter | Specification |
|---|---|
| Fiber Type | Single-mode 9/125 µm |
| Polish Type | APC (8°) |
| Insertion Loss | ≤ 0.30 dB |
| Return Loss | ≥ 60 dB |
| Wavelengths | 1310 / 1550 nm |
| Repeatability | ≤ 0.1 dB |
| Durability | ≥ 1000 mating cycles |
These values meet the requirements of GPON, XG-PON, FTTx, CATV and telecom backbone systems.
Mechanical & structural design
| Feature | Description |
|---|---|
| Connector Format | LC Simplex |
| Cable Size | 3.0mm |
| Ferrule | 1.25mm zirconia ceramic |
| Housing | High-impact polymer |
| Boot | Long strain-relief boot |
| Locking | LC push-pull latch |
| Operating Temp | –40°C to +75°C |
| Tensile Strength | ≥ 120 N |
The long boot and thick jacket absorb pulling force and prevent micro-bending, which helps maintain stable optical performance over time.

Professional Q&A
Q1: When should I choose 3.0mm instead of 2.0mm?
Use 3.0mm when the cable will be pulled, bent frequently, or installed outdoors. It provides much better mechanical protection.
Q2: Is LC APC required for PON networks?
Yes. Most GPON, XG-PON and CATV systems require APC connectors to reduce signal reflection.
Q3: Can LC APC 3.0mm be used in patch panels?
Yes. It fits standard LC adapters and panels, but offers stronger cable protection than thinner cords.
