Description
Why choose an adjustable FC connector?
In high-quality fiber assemblies, even a few microns of fiber height can affect optical loss.
That’s why adjustable connectors are preferred in professional cable manufacturing.
With this adjustable FC PC connector, you can:
-
Precisely control fiber end-face position
-
Achieve better polishing results
-
Reduce insertion loss variation
-
Improve yield in mass production
This is especially valuable for companies like Changzhou Fenxi Optoelectronics Technology Co., Ltd., where stable quality and high-volume output matter.
Compatible with 2.0mm and 3.0mm fiber cables
| Cable Diameter | Typical Use |
|---|---|
| 2.0mm | Indoor patch cords, device jumpers |
| 3.0mm | Telecom and backbone patch cords |
One connector design supports both sizes, making inventory and production much easier.

Professional Q&A
Q1: What advantage does the adjustable structure give?
It allows the ferrule position to be fine-tuned during polishing and assembly, giving better control of fiber end-face geometry and more stable optical performance.
Q2: Is FC PC suitable for FTTH systems?
Yes. FC PC connectors are widely used in FTTH, telecom, and enterprise networks where low insertion loss and reliable mechanical connection are required.
Q3: Can FC PC connect to FC APC?
No. PC and APC have different end-face geometry. They should never be mated together, as it causes high loss and may damage the ferrules.
