METHOD AND APPARATUS FOR CONSTRUCTION OF COMPACT OPTICAL NODES USING WAVELENGTH EQUALIZING ARRAYS

摘要

Example embodiments of the present invention relate to an optical node comprising of at least two optical degrees; a plurality of directionless add/drop ports; and at least one wavelength equalizing array, wherein the at least one wavelength equalizing array is used to both select wavelengths for each degree, and to perform directionless steering for the add/drop ports.

主权项

1. A reconfigurable optical add/drop multiplexer with directionless add/drop port support comprising:
a first line interface; a second line interface; a common port; a first wavelength equalizer with one optical input and one optical output, used to pass and block individual wavelengths from the first line interface to the common port; a second wavelength equalizer with one optical input and one optical output, used to pass and block individual wavelengths from the second line interface to the first line interface; a third wavelength equalizer with one optical input and one optical output, used to pass and block individual wavelengths from the common port to the first line interface; a fourth wavelength equalizer with one optical input and one optical output, used to pass and block individual wavelengths from the second line interface to the common port; a fifth wavelength equalizer with one optical input and one optical output, used to pass and block individual wavelengths from the first line interface to the second line interface; and a sixth wavelength equalizer with one optical input and one optical output, used to pass and block individual wavelengths from the common port to the second line interface.
