Single-mode Wavelength Independent Couplers

The Single-mode Wavelength Independent (Dual-window Broadband) Couplers employ Bandwidth-extending Technique (Asymmetrical Technique) to extend bandwidth up to ?40nm at 1310/1550nm channels by changing wavelength characteristics, so as to meet the coupling accuracy in two wavebands. Single-mode Dual-windows Broadband Couplers ensure the low Excess loss and PDL, have been widely used for test instruments, broadband light sources, bandwidth optical fiber networks.

  • Low Excess Loss
  • Good Directivity
  • Low PDL
  • Good Environmental Stability
