HOME 제품소개 Optical Couplers

 

 
 
Dual window Wideband Fiber Coupler, WIC(Wavelength Independent Coupler) is used to passively
split or combine light between two fibers.The service is fabricated using fused biconic tapering
technique. The coupling ratio is designed according to customer requirements. Various types
of connectors are available.
 
  - CATV
- Telecommunication
- FTTH
- Local Area Networks
- Test Equipment
 

- Low insertion & excess loss
- Excellent uniformity
- Low PDL
- High directivity
- Wide wavelength range
