	The replacement of dry heat in generic reliability assurance requirements for passive optical components (EI CONFERENCE) 会议论文 OAI收割 ICO20: Optical Devices and Instruments, August 21, 2005 - August 26, 2005, Changchun, China 作者: Zhang G.; Zhang G.; Zhang G. 收藏 \| 浏览/下载：24/0 \| 提交时间：2013/03/25 According to Generic Reliability Assurance Requirements for Passive Optical Components GR-1221-CORE (Issue 2 January 1999) reliability determination test of different kinds of passive optical components which using in uncontrolled environments is taken. 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.
