HOME 제품소개 Optical Couplers

 

 
 
Single window Standard Coupler(SSC) is used to passively split or combine light between two fibers. The device is fabricated using fused biconic tapering technique. The coupling ratio is designed according to customer requirements. Various type of connectors are available.
 
  - CATV
- Telecommunication
- FTTH
- Local Area Networks
  - Low insertion & excess loss
- Excellent uniformity
- Low PDL
- High directivity
