27、al, start of life dimensional, optical, mechanical and environmental performance requirements which a terminated and assembled singlemode 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 d

28、ifferent variants and grades of performance are permitted, product marking details are given in3.5. 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 accord

29、ance with Table 1 The intention is that this will be true irrespective of the manufacturing source(s) of the product. In all cases, the intermating of plug variants having different attenuation grades will result in an uncertain level of random attenuation performance. Table 1 - Ensured level of ran

41、ption The LC-APC 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 push-pull coupling mechanism. The optical alignment mechanism of the connectors is of a

42、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 rotation between mated connectors. A cover (dust cap) to protect the ferrule endface

43、 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 requirements must be met under all conditions. 3.2 Adaptor The adaptor has a zirconia cer

44、amic 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 for the sleeve that have directly compatible material properties to zirconia but th

45、e 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. 3.4 Dimensions Outline dimensions and other dimensions necessary to ensure intermateability or which af

46、fect 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 this is clearly stated. 3.5 Colour and marking Marking of the product shall be in the following order of pre

47、cedence: a) identification of manufacturer; b) manufacturing date code : year/week; c) manufacturers part number; d) variant identification number. The following colour scheme is preferred: Table 2 - Preferred colour scheme Delatch housing Adaptor Green Green NOTE The preferred Green is RAL 6024. EN
