coupler ratio: 40/60
Once the switch has been moved to the new position it will remain there until a drive pulse appears on the drive coil for the other path
high return loss and high extinction ratio
It is widely applied to blocking the unwanted noise signals in YDFA and fiber pump laser systems
1X2 DWDM Channel 8, 200 G, 1571.24 nm CWDM coupler ratio: 40/60The DWDM is designed for long haul transmission where wavelengths are packed tightly together. The 200 GHz spacing DWDM filters allow system designers optimal configuration flexibility. They featured with a low insertion loss, high channel isolation and excellent environmental stability and reliability. They can be used for channel add drop, DWDM network, wavelength routing and fiber optical filter. FEATURES1. 6 nm Channel Spacing Wide Pass BandHigh
