Couplers, Splitters & Combiners

1×3 80µm Polarization Maintaining (PM) Fiber Optic Couplers/Splitters

The reduced cladding (80µm ) optical fiber splitter is a passive device that splits or combines light at 1550 nm in forms of 1×3 or 3×1 for most frequent used optical routing designs. There are many various applications requiring this type of coupler such as optical amplifier, power monitoring, coherent communication and fiber gyroscope. Couplers are highly efficient in splitting light with little loss, about 0.2dB per joint, but incur significant losses when combining lights; for example, a 50/50 coupler produces a 50% loss to each beam when combined.
