Single Window Singlemode Tree couplers (1310nm or 1550nm) are bi-directional high-port count units for splitting or combining optical signals over 1310nm or 1550nm wavelength windows. They are fused bionics tapered couplers cascaded in series to achieve the desired port configuration. These couplers are used to branch 1(2) input fibers into N (3, 4, 8,...16 ..) out put fibers with minimum loss.
