HOME Products Optical Couplers

 

 
 

Single window Wideband Fiber Coupler, WFC(Wavelength Flattened Coupler) 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 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
