26、mensional, optical, mechanical and environmental performance requirements which a terminated and assembled multimode resilient alignment sleeve LC-PC duplex connector set (plug / adaptor / plug) must meet in order for it to be categorised as an European Standard product. Since different variants and
27、 grades of performance are permitted, product marking details are given in 3.5. 1.2 Intermateability Although all products conforming to the requirements of this European Standard will intermate, the resulting level of random attenuation performance will only be ensured in accordance with Table 1. T
28、he intention is that this will be true irrespective of the manufacturing source(s) of the product. A simplex plug can be connected in a duplex adaptor without degrading the level of performance. 1.3 Operating environment The tests selected combined with the severities and durations are representativ
29、e of an indoor environment typically, but not limited to, that found in generic cabling on commercial premises as defined as in ISO/IEC 11801 and EN 50173 and specified as IEC category C. 1.4 Reliability Whilst the anticipated service life expectancy of the product in this environment is 20 years, c
30、ompliance with this European Standard 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 European Standard does not guarantee the manufacturing consistency of the product. This sh
31、ould be maintained using a recognised quality assurance programme. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed

37、 ISO/IEC 11801 Information Technology - Generic cabling for customer premises 3 Description The LC-PC duplex connector is a single position plug connector set of plug adaptor plug configuration characterised by cylindrical, spring loaded butting ferrules of 1,25 mm nominal diameter and a latched pus
38、h-pull coupling mechanism. The optical alignment mechanism of the connectors is of a resilient sleeve style 3.1 Plug The plug features a cylindrical zirconia ceramic ferrule and a latched push-pull mechanism. It has a single male key which is used to limit and may be used to orientate, the relative
39、rotation between mated connectors. A cover (dust cap) 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 zirconia but the endface and performance requi
40、rements must be met under all conditions. 3.2 Adaptor The adaptor has a zirconia ceramic resilient alignment sleeve. The mounting style is duplex rectangular flange equipped with snap-latches. Covers (dust caps) shall be provided to protect each port of the adaptor. Alternative materials may be used
41、 for the sleeve that have directly compatible material properties to zirconia but the performance requirements must be met under all conditions. 3.3 Materials Materials which are not specified or which are not specifically described are left to the discretion of the manufacturer. - 7 - EN 50377-7-1:
42、2004 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 dimensions are not in agreement with an IEC Interface Standard
43、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) manufacturers part number; d) variant identification number.
