Polarization Maintaining (PM)

The field of application of Polarization Maintaining elements has expanded beyond traditional markets to brand new ones, from research to industrial environments: Biomedicine, Spectroscopy, Metrology, Sensorics, Telecommunications, Lasertechnology, Surveillance & Security, Lithography.

DIAMOND supplies high-quality solutions to polarization maintaining (PM)

and polarizing (PZ) fiber optical interfaces for optimal control of the signal’s

polarization state. Low insertion losses (IL) combined with high polarization

extinction ratios (PER) and higher return losses (RL) are achieved over very

broad spectral ranges thanks to a combination of accurate optical and

mechanical design.

Available connector types are: E-2000™, F-3000™ SC, FC, LSA (DIN), AVIM, Mini-AVIM and DMI.

E-2000™ PM available as IP65 and/or IP65/EtO.




  • Proprietary Active Core Alignment (ACA) process for minimal eccentricity between fiber’s core and ferrule to guarantee unmatched low insertion losses
  • Active Polarization Orientation (APO) procedure for optimal alignment between the mechanical connector’s key and the true polarization (fast or slow) axis to guarantee the highest PER in a mated configuration
  • Optimized polishing techniques for excellent return losses values
  • 100% front face inspection
