Abstract
A redundant wavelength division multiplexing (WDM) device including a first common port which includes a collimator configured to transmit a first optical beam. The first beam includes a first plurality of optical signals. A second common port includes a collimator configured to transmit a second optical beam that includes a second plurality of optical signals. The second common port is spaced apart from the first common port and a plurality of filters define an optical path for each of the first optical beam and the second optical beam. Each filter is oriented to interact with each of the first optical beam and the second optical beam. A method of processing light includes transmitting one of the first optical signals of a first wavelength through a first filter and transmitting one of the second optical signals of the first wavelength through the first filter.
