A method of assembly is presented for a multi-wavelength optical monitor
(MWOM) for use in fibre optic telecommunication networks. The method
allows coarse optimisation to be used to align an input optical fibre and
detector array relative to a wavelength division demultiplexing element.
The detector array output data are transformed with a digital signal
processor into relative intensities of the components of the spectrum or
spectral parameters of telecommunication channels.
