We use fused biconical taper technique to build a series of couplers. According to the different operating bandwidths, we have wide band couplers, dual window couplers, three-window couplers, and so on.

FEATURES

  • Low insertion loss and low PDL
  • High reliability& High stability
  • RoHS compliant

APPLICATIONS

  • EDFA
  • CATV Passive Network WAN
  • FTTH
