First Claim
Patent Images
1. A wavelength cross connect comprising:
- a plurality of ports comprising at least one input port and at least one output port;
for each input port, a respective dispersive arrangement;
for each output port, a respective dispersive arrangement that multiplexes any wavelength signals re-directed towards the dispersive arrangement;
a plurality of routing elements for re-directing wavelength signals between the dispersive arrangement(s) of the at least one input port and the dispersive arrangement(s) of the at least one output port;
wherein at least two of the ports are configured to have differing performances through selection of respective dispersive arrangements having differing characteristics.

Abstract
A wavelength cross connect is provided in which there is a dispersive arrangement per port for each input port and each output port. Some of the dispersive arrangements have differing characteristics so as to result in different performances at the ports. The dispersive arrangements can differ in the selection of different dispersive elements or differing coupling optics. A particular implementation features a first set of waveguide dispersive elements having first performance characteristics, and a second set of waveguide dispersive elements having second performance characteristics.

19. A wavelength cross connect comprising:
-
a plurality of ports comprising at least one port that functions as both an input port and an output port;
for each port, a respective dispersive arrangement;
a plurality of routing elements for re-directing wavelength signals between ports;
wherein for each port functioning as an input port, the respective dispersive arrangement performs a demultiplexing function on a respective multi-wavelength signal received at the input port;
for each port functioning as an output port, the respective dispersive arrangement performs a remultiplexing function of any wavelength signals re-directed towards that output port by the routing elements;
wherein at least two of the ports are configured to have differing performances through selection of respective dispersive arrangements having differing characteristics. - View Dependent Claims (20)

21. A wavelength cross connect comprising:
-
a plurality of ports comprising at least one input port and at least one output port;
for each input port, a respective dispersive arrangement;
for each output port, a respective dispersive arrangement that multiplexes any wavelength signals re-directed towards the dispersive arrangement;
for each of a plurality of wavelength channels, a respective beam processing elements for re-directing at least part of the wavelength channel between the dispersive arrangement(s) of the at least one input port and the dispersive arrangement(s) of the at least one output port;
wherein at least two of the ports are configured to have differing performances through selection of respective dispersive arrangements having differing characteristics.
