2um 3x3 PM Monolithic Single Mode Coupler

Product Description:

The Monolithic Single Mode fusion couplers feature compact size, very low insertion loss and polarization dependence, excellent environmental stability and loss uniformity. These couplers were designed for power splitting or combining of optical signals. They are widely used for optical modules and the fiber sensors, fiber testing instruments.
