Single-Mode Standard Coupler

Coupler is a kind of passive components, its main function is to redistribute the input light wave as required, avoid interrupting modulating signals. In the application of communication, some important technique parameters are must be considered, including center wavelength, bandwidth, typical excess loss, coupling ratio and the necessary environmental stability. All the optical fused couplers which employ FBT technique are proven to have high performance in applications. We are taking specific techniques to handle the empty end so as to eliminate reverse-directional reflection. Our Couplers ensure above-60dB directivity, and long-time good stability.
