The WaveShaper 16000A Reconfigurable Optical Processor is a programmable wavelength-selective MxN optical filter with control of filter shape and phase on each input/output port combination. The instrument has a total number of 20 optical ports. These can be configured by software commands to 1 x 19, 4 x 16, 8 x 12 or 10 x 10. All these port combinations work bi-directional, therefore also 19 x 1, 16 x 4 and 12 x 8 are included. Covering the entire C-band, the WaveShaper 16000A combines precise control of filter wavelength, bandwidth, shape and phase with the ability to switch and combine multiple signals in an “Add” or “Drop” configuration. The WaveShaper 16000A in a 1x16 configuration also supports power splitting, broadcasting and the ability to create programmable interferometers.
