Complete Your Setup
LBTEK polarization-maintaining single-mode fiber patch cords feature 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/APC connectors provide even higher return loss.
- Extinction ratio ≥30dB
- Connector FC/APC
- Wavelength 780-1550nm optional
