1x2/2x2 Polarization Maintaining (PM) Fiber Optic Couplers/Splitters – Micro-Optic PER 29dB

SKU: HEPC

The FC Series PM fiber optic coupler uses micro-optic technology in a compact package, offering exceptionally high polarization extinction ratio and broad operational wavelength coverage. It is designed for applications where fused PM couplers fall short of stringent performance requirements and is compatible with all PM fiber types. The compact platform supports seamless integration of additional components without increasing size. It operates by transmitting one polarization state while blocking the orthogonal one. These couplers efficiently split light with minimal loss — approximately 0.2 dB per junction — but experience significant loss in beam-combining applications; for instance, a 50/50 coupler results in a 50% loss per beam when combining. For efficient beam combining, see our dedicated PM fiber combiners.
