The test condition of High Temperature Storage Test (Dry Test) and Damp Test is in below sheet. Except for humidity condition  all is same. In order to save test time and cost  after a sires of contrast tests  the replacement of Dry Heat is discussed. Controlling the Failure mechanism of dry heat and damp heat of passive optical components  the contrast test of dry heat and damp heat for passive optical components (include DWDM  CWDM  Coupler  Isolator  mini Isolator) is taken. The test result of isolator is listed. Telcordia test not only test the reliability of the passive optical components  but also test the patience of the experimenter. The cost of Telcordia test in money  manpower and material resources  especially in time is heavy burden for the company. After a series of tests  we can find that Damp heat could factually test the reliability of passive optical components  and equipment manufacturer in accord with component manufacture could omit the dry heat test if damp heat test is taken first and passed.
