Selecting the correct patch cord depends on your application, distance, equipment type, and network design. Use the following checklist.
1 Choose by Application Scenario
2 Choose the Correct Fiber Type
- Long-distance: OS2 single-mode
- Short-distance (≤100 m): OM3/OM4 multimode
- Ultra high-density: OM5 or MPO/MTP
- FTTH: OS2 SC/APC (industry standard)
3 Choose the Connector Type (Very Important)
Tip: LC ↔ SC is NOT interchangeable without an adapter.
4 Check the Polishing Type: UPC vs APC
Do not mix UPC with APC — it causes high insertion loss.
5 Cable Diameter & Jacket Material
- 2.0 mm → flexible, indoor
- 3.0 mm → more durable
- LSZH → low-smoke, halogen-free (recommended for buildings)
- PVC → general indoor use
Fiber Patch Cord Structure Explained
A standard patch cord is composed of:
- Fiber core (SM or MM)
- Kevlar strength member
- Outer jacket (PVC/LSZH)
- Connector housing
- Ceramic ferrule (zirconia)
- Polished end-face (UPC/APC)
Choosing the right fiber optic patch cord requires matching your network’s fiber type, connector interface, polishing, structure, and application scenario. A properly selected patch cord ensures lower insertion loss, higher stability, and long-term reliability. By evaluating equipment ports and installation environments, you can significantly improve network performance and avoid signal issues.
