Polarization Maintaining Coupler Module - 1x3, 1x4 or 1x8

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.

Features

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

Applications

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