450nm 1x2 PM Fused Coupler

Fused couplers are used to split optical signals between two (or more) fibers or to combine optical signals from two (or more) fibers into one fiber. They are constructed by fusing and tapering the fibers together. This method creates a simple, rugged, compact method of splitting or combining optical signals. Typical excess losses are as low as 0.2 dB, while split ratio tolerances range from ±5% to ±0.5% at design wavelengths depending upon the splitting ratio. These devices are bidirectional and offer low backreflection and insertion losses
