Complete Your Setup
The LBTEK polarization-maintaining single-mode fiber patch cord features high-quality ceramic connectors at both ends, which undergo high-precision polishing and precise connector alignment. Each patch cord ensures low insertion loss and a high extinction ratio of ≥30dB at the specified wavelength. Both ends of the patch cord are equipped with protective caps to prevent dust or other contaminants from damaging the ferrule end faces, ensuring high stability and reliability. The FC/PC to FC/APC adapter allows connection between FC/PC on one end and FC/APC on the other, enabling fiber connector conversion.
