You can use a variety of fiber optic connectors for a 14 cm cable, including LC, SC, ST, FC, MU, MT-RJ, MPO, and others, compatible with single-mode or multimode fibers.

Recommended Connector Types

For a short 14 cm fiber optic cable, the following connectors are suitable:

1. LC (Lucent Connector) – Small form factor, push-pull design, ideal for high-density applications .
2. SC (Subscriber Connector) – Snap-in, widely used in telecom and data networks .
3. ST (Straight Tip) – Bayonet-style, common in legacy networks .
4. FC (Ferrule Connector) – Threaded, high vibration resistance, suitable for rugged environments .
5. MU (Miniature Unit) – Compact, used in high-density patch panels .
6. MT-RJ (Mechanical Transfer Registered Jack) – Duplex connector, small footprint .
7. MPO/MTP (Multi-Fiber Push-On) – Multi-fiber, high-density applications .
8. ESC (Enterprise Systems Connector) – Industrial and telecom use .
9. FDDI (Fiber Distributed Data Interface) – Legacy network applications .
10. FSD / FSMA / FSD – Specialty connectors for industrial or medical devices .
11. SCRJ / SCRJ Duplex – Compact duplex connectors .
12. Power Jack Fiber – For hybrid electrical/fiber applications .
13. SMA – Threaded, precision alignment for lab or instrumentation .
14. TNC Fiber – Ruggedized threaded connector .
15. VF-45 – High-performance multimode connector .
16. ODU MEDI-SNAP® – Sterilizable, medical-grade fiber connector .
17. LC Duplex – Two fibers in one connector, saves space .
18. SC Duplex – Duplex version of SC for paired fibers .
19. ST Duplex – Duplex ST for legacy duplex links .
20. FC Duplex – Threaded duplex for high stability .
21. LC/APC – Angled physical contact for low back reflection .
22. SC/APC – Angled ferrule for single-mode low-loss connections .
23. LC/UPC – Ultra-polished connector for single-mode fiber .
24. SC/UPC – Standard polished connector for telecom .
25. ST/UPC – Standard tip for multimode or single-mode .
26. MU/APC – Angled miniature connector for high-density panels .
27. MPO/APC – Multi-fiber angled connector for low reflection .
28. LC Simplex – Single fiber, small form factor .
29. SC Simplex – Single fiber, easy to install .
30. Custom Ferrule Connectors – For lab or prototype short cables .

Considerations for a 14 cm Cable

• Mode Compatibility: Ensure the connector matches the fiber type (single-mode or multimode) and core diameter (e.g., 50 µm, 62.5 µm, 9 µm).
• Connector Style: Push-pull (LC, SC) or threaded (FC, SMA) depending on mechanical stability needs.
• Insertion Loss: Short cables like 14 cm require low-loss connectors to maintain signal integrity.
• Duplex vs Simplex: Duplex connectors allow two fibers in one connector, useful for bidirectional links.
• Adapter Compatibility: Verify that the connectors can mate with existing adapters or devices. These connectors are available from suppliers such as Mouser, DigiKey, Farnell, CommScope, and RS Components, with datasheets and parametric filters to select the exact type for your fiber specifications .
