Single-mode Standard Couplers

Our Single-mode Couplers have reached the leading edge level in the world because of its excellent reliability and high performance. The extremely low Excess loss and PDL have greatly improved components reliability and long-time stability. 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.

  • Low Excess loss
  • Good Directivity
  • Low PDL
