How DWDM wavelengths are deployed and explain optical power measurement? danielmathew 18-December-2008 09:24:37 PMComments Yes i think its true that optical power measurements used as a test source to measure the power...

Posted by waqqas1 The above detail is correct for more detail information please visit following links: ->http://www.eetimes.com/story/OEG20040129S0029 ->http://www.itu.int/ITU-T/newslog/Standard+Extends+DWDM+Distance.aspx Posted by sagitraz If DWDM wavelengths are to be deployed in the fiber, then optical power measurements or use the DWDM source itself as a test source. This is because optical fiber loss varies with wavelength. Also optical power measurement should be made in the same direction as the transmission system. Measurements in both directions will result in slightly different readings. Also, all fiber connections need to be clean, including the connections on the test equipment. Posted by casey |
