Polarization Maintaining PM Fiber Optic Patch Cord with High Extinction Ratio
Description
PM (Polarization Maintaining) components including PM isolator, PMcirculator,PM WDM, PM patchcord PM collimator and so on. Wide bandwidth, high return loss, high extinction ratio, high isolation with low insertion loss over a wide wavelength range and excellent environmental stability and reliability. Widely used in Polarization Maintaining Fiber Amplifiers, Fiber Lasers, High Speed Communication Systems and Instrumentation Applications.Our Pm patch cords are available with FC and FC/APC connector options or as a pigtail assembly. The PM connector key is aligned to the slow axis as default. Several fiber types are available from Nufern and Corning offering wavelengths in the spectral ranges 400nm up to 2050nm.
Features
• Low insertion Loss
• High extinction ratio
• High return ratio
• Excellent environmental stability and reliabity
