Abstract:
A bi-directional isolator comprising:a first port for launching a first optical signal comprising at least one wavelength channel from a first set of wavelength channels, and for outputting a second optical signal comprising at least one wavelength channel from a second set of wavelength channels, independent of the first set of wavelength channels; a second port for launching the second optical signal, and for outputting the first optical signal; first routing means for directing the first optical signal from the first port to the second port, while preventing signals comprising at least one wavelength channel from the second set of wavelength channels from passing thereto; and second routing means for directing the second optical signal from the second port to the first port, while preventing signals comprising at least one wavelength channel from the second set of wavelength channels from passing thereto.
