1.3 Operating environment The tests selected combined with the severities and durations are representative of a controlled environment typically, but not limited to, that defined as in EN 61753-051-3 and IEC Category C. 1.4 Reliability Whilst the anticipated service life expectancy of the product in this environment is 20 years, compliance with this specification does not guarantee the reliability of the product. This should be predicted using a recognised reliability assessment programme. 1.5 Quality assurance Compliance with this specification does not guarantee the manufacturing consistency of the product. This should be maintained using a recognised quality assurance programme. 2 Normative references The following referenced documents are indispensable for the application of this document.

- 7 - EN 50378-3-1:2007 3 Description 3.1 General The DWDM module, is a passive component providing a transition between 1 buffered fibre and N individual buffered fibre cables (N = 4,8). The product maybe unconnectorised or connectorised. When the product is connectorised the connectors shall be selected from the EN 50377 series. 3.2 Cable fixing structure
No cable fixing element is foreseen as the module is terminated on buffered fibres. The module is to be secured against high accidental pulling forces. 3.3 Materials
The material of the module housing shall be left to the discretion of the manufacturer. For plastic materials preferred materials shall have Low Smoke Zero Halogen characteristics. 3.4 Dimensions
Outline dimensions and other dimensions necessary to ensure interchangeability or which affect performance, are specified here. All other dimensions are left to the discretion of the manufacturer.
3.5 Marking
Marking of the product shall be in the following order of precedence:
a) identification of manufacturer; b) manufacturing date code: year / week; c) manufacturers part number; d) variant identification number.

The defined DWDM modules variants are given in Table 1.
