Fused Fiber Optic Splitter (standard double window Coupler 1XN) standard double window Coupler 1XN splitter is connected in series by the N-1 1X2 splitter made. In both 1310nm and 1550nm communication windows are ± 40nm bandwidth, so these two can meet the bandwidth requirements of precision spectroscopic two wavelengths, and meet the low excess loss, low polarization sensitivity loss. WFC devices are widely used in broadband light source, measuring instruments and broadband fiber optic network.
