32、sembled singlemode resilient alignment sleeve MU-APC simplex connector set (plug adaptor plug) must meet in order for it to be categorised as an EN standard product. Since different variants and grades of performance are permitted, product marking details are given in Section 3.5. 1.2 Intermateabili
33、ty Although all products conforming to the requirements of this specification will intermate, the resulting level of random attenuation performance will only be ensured in accordance with Table 1. The intention is that this will be true irrespective of the manufacturing source(s) of the product. In
34、all cases, the intermating of plug variants having different attenuation or return loss grades will result in an uncertain level of random attenuation performance. When intermating plug variants having different return loss grades, the resulting level of return loss can not be assured to be any bett
35、er than the worst return loss grade Similarly, the intermating of a grade P plug with a grade Q plug will result in an uncertain level of random attenuation performance. Table 1 - Ensured level of random attenuation Plug variant/Attenuation grade P QPPPQP1.3 Operating environment The tests selected
36、combined with the severities and durations are representative of an IEC Category U environment and the ES 200 671 environment. 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 reli
37、ability 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. Li

48、 Copy, (c) BSIEN 50377-10-2:2005 - 8 - 3 Description The MU-APC connector is a single position plug connector set of plug adaptor plug configuration characterised by a cylindrical, spring loaded butting ferrule of 1,25 mm nominal diameter and a push-pull coupling mechanism. The optical alignment mec
49、hanism of the connectors is of a resilient sleeve style. 3.1 Plug The plug features a cylindrical zirconia ferrule and a push-pull mechanism. It has a single male key which is used to limit and may be used to orientate, the relative rotation between mated connectors. A cover (dustcap) to protect the ferrule endface when the connector is in the unmated condition shall be provided. Alternative materials may be used for the ferrule that have directly compatible material properties to the specifie
