1x2/2x2 Polarization Maintaining (PM) Fiber Optic Couplers/Splitters – Fused PER 22dB

The FC Series PM fiber optic coupler uses fused biconical taper technology in a compact package, offering good uniformity, low excess loss, and very low polarization sensitivity for splitting or combining light over a wide wavelength range. Cost depends on polarization extinction ratio grade. It handles up to 1 W at 1550 nm, with lower limits at shorter wavelengths; the HPFC Series supports higher power. Couplers have ~0.2 dB loss per split joint, but combining light causes higher losses — e.g., a 50/50 combiner loses 50% from each beam; for combining, see our Combiner products. A fused fiber coupler transmits light from both polarization axes. To block one polarization axis, our micro-optic coupler provides this functionality.
