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
