29、alignment sleeve SC-RJ connector set (plug / adaptor / plug) must meet in order for it to be categorised as an EN standard product. Product marking details are given in 3.5. 1.2 Intermateability Products conforming to the requirements of this specification will intermate and give the specified level
30、 of random attenuation and random return loss performance provided the same fibre type is used. The intention is that this will be true irrespective of the manufacturing source(s) of the product. 1.3 Operating environment The tests selected combined with the severities and durations are representati

32、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
33、 maintained using a recognised quality assurance programme. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications.

40、 cylindrical, spring loaded butting ferrules of 2,5 mm nominal diameter and a push-pull coupling mechanism. The optical alignment mechanism of the connector is of a resilient sleeve style. 3.1 SC-RJ plug The plug features two cylindrical zirconia ceramic ferrules and a push-pull coupling mechanisms.
41、 Alternative materials that have material properties directly compatible with zirconia may be used for the ferrules, but the endface and performance requirements must be met under all conditions. The plug housing has a single male key which is used to limit the relative rotation between mated plugs.
42、 A cover (dust cap) to protect the ferrule endface when the plug is in the unmated condition is provided. 3.2 SC-RJ adaptor The adaptor consists of two zirconia ceramic resilient alignment sleeves and two push-pull coupling mechanisms, one for each sleeve. Alternative materials that have material pr
43、operties directly compatible with zirconia may be used for the sleeves. The mounting style is a rectangular flange with 2 hole fixing. The adaptor can either connect to a SC-RJ plug or to two simplex SC plugs according to EN 61754-4. The adaptor housing has three female keys which are used to limit
44、the relative rotation between mated plugs. One key is used to position the SC-RJ plug and the other two keys are used to orientate the two simplex SC plugs. Covers (dust caps) are provided to protect each duplex port of the adaptor. 3.3 Materials Materials which are not specified or which are not sp
45、ecifically described are left to the discretion of the manufacturer. 3.4 Dimensions Outline dimensions and other dimensions necessary to ensure intermateability or which affect performance are specified. All other dimensions are left to the discretion of the manufacturer. Where the mating face limit
46、 dimensions are not in agreement with an IEC Interface Standard this is clearly stated. 3.5 Colour and marking Marking of the product shall be in accordance with 2.6.2 of EN 186000-1 in the following order of precedence: a) identification of manufacturer; b) manufacturing date code: year / week; c)
47、manufacturers part number; d) variant identification number. The preferred colour scheme is given in Table 1.
