Polarization maintaining coupler modules combine multiple incoming optical fiber inputs into one output, while maintaining the polarization state of the light. It can aslo be used as a PM splitter.

Our PM coupler modules are assembled using thin-film filter-based 1x2 and 1x3 PM optical fiber couplers, with center wavelengths at 1310nm or 1550nm, and bandwidth of +/-30nm.


  • High extinction ratio
  • Low excess loss and WDL
  • High stability and reliability
  • Epoxy-free optical path


  • Optical fiber sensor systems
  • Optical amplifiers
  • Fiber laser systems


Module Dimensions: 1x3 or 1x4 160x140x10mm; 1x8 160x160x10mm.

Ordering Information:

w: Center Wavelength in nm; w=1550 or w=1310.
a: Port Number of the coupler; a=1x3, a=1x4 or a=1x8;.
c: Fiber Pigtail Type; c=1 for 0.9mm loose tube pigtail; c=3 for 3mm cable jacket, etc.
d: Connector Type, d=FA for FC/APC, d=SU for SC/UPC, d=N for no connectors, etc.

Example: PMCM-1550-1x8-3-FU
