hi,
Circulator Bidirectional is a circulator. It is bidirectional, with wavelength dependent isolation, insertion loss and return loss.
If the parameter Calculate graphs is enabled, the component will generate graphs with the wavelength dependence of the insertion loss, isolation and return loss.
Optical Delay Generates optical signal delays. The delay is added by sending NULL signals to the output port.
Electrical Delay Generates electrical signal delays. The delay is added by sending NULL signals to the output port.
