The C-Band PM Fiber Patch Cord is designed for polarization-sensitive optical transmission, testing, and component interconnection applications. It uses PM1550 polarization-maintaining fiber with slow-axis alignment to preserve the polarization state and maintain stable optical performance across C-band systems.

4. FAQ
Q1: What does slow-axis alignment mean for this PM fiber patch cord?
Slow-axis alignment means that the polarization axis of the PM1550 fiber is aligned to the defined orientation of the SC/APC connector. This helps maintain a stable polarization state when the patch cord is connected to compatible polarization-maintaining components.
Q2: Can the connector type, cable length, or axis orientation be customized?
Yes. Connector type, cable length, loose-tube diameter, cable color, axis alignment, identification labels, and strain-relief structure can be configured according to the customer’s application requirements. Custom specifications should be confirmed before production.
