Couplers, Splitters & Combiners
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.

System integration
Integration and compatibility
Use these checks to connect 1x2/2x2 Polarization Maintaining (PM) Fiber Optic Couplers/Splitters – Fused PER 22dB to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.
- Optical interface and fiber
- Fiber Cover: 250µm, 900um tube, Special · Fiber Type: PM1550, PM400, PM460, PM630, PM780, PM850, PM980, PM1950
- Specify connector polish and fiber architecture together. FC/PC, FC/APC and SMA interfaces, and single-mode, multimode and polarization-maintaining fibers, impose different return-loss, mode-field and alignment requirements.
- Wavelength and loss budget
- Wavelength: 480nm, 450nm, 430nm, 410nm, 530nm, 540nm, 560nm, 630nm, 670nm, 1480nm, 1060nm, 1310nm, 1550nm, 780nm, 850nm, 980nm, 1600nm, 2000nm, 2039nm, 1950nm
- Check the Couplers, Splitters & Combiners passband, insertion loss, return loss and power handling at the actual source wavelength; a nominal telecom-band label is not a substitute for the configured range.
