Optical wavelength division multiplexers (WDM) were tested for performance degradation as a result of temperature cycling, shock and pulling on the fiber leads to determine tensile strength. The WDM components tested use multidielectric coatings to separate two channels, one ranging from 0.75 to 0.95 micron and the other from 1.2 to 1.6 microns. The optical crosstalk remained constant under the various tests and the insertion loss variation was small.
