Examples are tuneable chromatic dispersion compensators, wavelength selective

29、switches and optical channel monitors. Optical amplifiers are not included in this list, but are treated in IEC 61291-5-2. For reliability qualification purposes, some information about the internal components, parts and interconnections is needed; these internal parts are treated as black boxes. Th

30、is standard gives requirements for the evaluation of DM reliability by combining the reliability of such internal black boxes. The objectives of this standard are the following: to specify the requirements for the reliability qualification of DMs; to give the minimum list of reliability qualificatio

31、n tests, requirements on failure criteria during testing and on reliability predictions, and give the relevant normative references. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

36、e purposes of this document, the following terms and definitions apply. 3.1.1failure non-compliance to product specification or change in parameters as set by the standard or agreed by the customer and supplier 3.1.2qualification commonly used as the abbreviation for reliability qualification Note 1

37、 to entry: It is used as a formal testing to determine whether or not the product is suitable for telecom applications and, therefore, “pass or fail” is the expected outcome Note 2 to entry: This is different from a reliability test, which is in nature a reliability “engineering test”. Reliability t

38、ests are designed to understand the reliability consideration or estimate the reliability of the product. Pass or fail is not the main output. 3.1.3reliability minimum period of DM continuous operation without failure at specified operating and environmental conditions 3.1.4probability to perform re

39、quired functions at specified operating and environmental conditions Note 1 to entry: The reliability of a DM is expressed by either of the following two parameters: mean time between failure (MTBF) and failures in time (FIT): the MTBF is the mean period of DM continuous operation without any failur

40、e at specified operating and environmental conditions; the FIT is the number of failures expected in 109device-hours at specified operating and environmental conditions. 3.2 Abbreviated terms DM dynamic module DS detail specification ESD electrostatic discharge FIT failure in time FMEA failure mode

42、 the commercial market and involve different technologies, the requirements included in this standard will need to be reviewed as technology progresses. 4.2 General consideration approach It is worth emphasizing the fundamental approach of reliability qualification adopted in this standard: a) Any p

43、arts that can be effectively qualified on their individual levels shall be qualified at that level. Their qualification shall be based on IEC standards or other industrial standards in the absence of such IEC standards. b) The qualification tests required at DM level shall be based on the degradatio

44、n mechanisms and failure modes that cannot be effectively detected in the lower part levels. At the DM level, the qualification tests shall not attempt to discover or identify those degradation mechanisms and failure modes that can be discovered in the lower assembly levels than the final product le

45、vel. For example, if all parts in the DM can be effectively tested for damp heat-accelerated degradations, there is no need to repeat the damp heat test at the DM level. 4.3 DM product design A DM is an assembly of various components, parts and interconnections. There are two basic designs in the cu

46、rrent commercial DM market: a) Design 1: parts (as a general term that includes components, parts and interconnections used to build a DM from the of point of view of this standard) are packaged separately. Their packages are usually either hermetic or moisture-resistant. They are integrated into a

47、housing (usually non-hermetic or not moisture-resistant). b) Design 2: some parts used in DMs are unpackaged basic optical elements (e.g. crystals, lenses, mirrors, etc.). These parts cannot be effectively qualified by themselves. These parts/elements are integrated and packaged inside a hermetic bo

48、x or moisture-resistant box. In Design 1, the individual parts can be tested and qualified individually and therefore, the DM qualification does not have to repeat the tests that are performed in the part levels for the same degradation mechanisms and failure modes. In Design 2, the DM qualification

49、 is again focused on the tests that cannot be effectively performed in the lower assembly levels (i.e., the basic part level). However, in this case there are usually more tests required since the parts cannot be effectively tested at the part level individually. Due to the differences in the designs, and therefore different mechanisms and failure modes, different qualification test approaches have to be developed separately. They are described in 5.4.4
