28、nvironmental requirements a unconnectorised or connectorised 100/200 GHz DWDM module has to fulfill in order to be characterised as an EN standard product. Since different variants are permitted, product-marking details are given in 2.5. The wavelength grid shall be according ITU Recommendation G 67
29、1 (see Annex B). 1.2 Interchangeability Environmental performance requirements which DWDM module terminated on single mode fibre B1.1 without connectors shall meet in order to be categorised as an EN standard product. The module is to be placed in an enclosure to protect it from accidental pulling f
30、orces. All products conforming to the requirements of this specification which meet the transmission and dimensional requirements will be interchangeable. This will be ensured independently of the manufacturing source(s) of the modules. 1.3 Operating environment The tests selected combined with the
31、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 specificati
32、on 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 q
33、uality assurance programme. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies.

37、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
38、 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 in
39、terchangeability 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) manu

46、10 - 6.2 Test and measurement methods All tests and measurements have been selected from EN 61300 series. Unless otherwise stated in the individual test details all optical attenuation measurements shall be performed over the related C and L wavelength band. No deviation from the specified test meth
47、od is allowed. Remark (see Annex B) : The ITU defines the channels in terms of frequency. It is very common to see specifications of wavelengths where the 100 GHz (ITU channel spacing) corresponds to 0,8 nm. This is technically true only at the centre of the C band (1 550 nm). The 200 GHz spacing co
48、rresponds to 1,6 nm interval. The spacing values in nm are only given for indication, the normative values are specified in GHz. 6.3 Test sequence All products shall be subjected to Tests 1 to 7 following which there is no defined sequence in which other tests (see Annex A) must be run. 6.4 Pass/fai
49、l criteria A product will have met the requirements of this specification provided no failures occur in the sample group for any test. In the event of a failure occurring, the test shall be re-run using a sample size double that of the original. 7 Test report A fully documented test report and supporting data shall be prepared and must be available for inspection as evidence that the tests described in Clause 8 have bee
