25、ns the initial, start of life dimensional, optical, mechanical and environmental performance requirements which a terminated and assembled multimode MT-RJ connector set (plug adapter plug) must meet in order for it to be categorised as an EN standard product. Since different variants are permitted,

26、product marking details are given in 3.5. 1.2 Intermateability All products conforming to the requirements of this standard will intermate and give the specified level of random attenuation and random return loss performance provided the same core size is used. The intention is that this will be tru

27、e irrespective of the manufacturing source(s) of the product. 1.3 Operating environment The tests selected combined with the severity and duration are representative of a customer premise protected environment as defined in EN 50173 and ISO/IEC 11801 and as specified in category C per IEC 61753-1. 1

28、.4 Reliability Whilst the anticipated service life expectancy of the product in this environment is 20 years, compliance with this standard does not guarantee the reliability of the product. This should be predicted using a recognised reliability assessment programme. 1.5 Quality assurance Complianc

29、e with this standard does not guarantee the manufacturing consistency of the product. This should be maintained using a recognised quality assurance programme. 2 Normative references EN 50173 Information Technology - Generic cabling systems EN 61300 series Fibre optic interconnection devices and pas

35、 is a single position plug connector set of plug adapter plug configuration characterised by a spring loaded butting rectangular ferrule with two optical fibres and a latched push-pull coupling mechanism. The optical alignment mechanism of the connectors is of precision pin and hole type. 3.1 Plug T

36、he plug features a rectangular composite ferrule and a latch coupling mechanism. A cover (dust cap) to protect the ferrule endface when the connector is in the unmated condition shall be provided. 3.2 Adapter The adapter has no role in the final alignment mechanism. The mounting style is - rectangul

37、ar flange - 2 hole. Covers (dust caps) may be provided to protect each port of the adapter. 3.3 Materials Materials which are not specified or which are not specifically described are left to the discretion of the manufacturer. The material for the ferrule is filled composite silica and guide pins a

38、re of stainless steel. Alternative materials, which have compatible material properties, may be used as long as endface and performance requirements are met under all conditions as specified in this document. 3.4 Dimensions Outline dimensions and other dimensions necessary to ensure intermateability

39、 or which affect performances are specified. All other dimensions are left to the discretion of the manufacturer. Where the mating face limit dimensions are not in agreement with the IEC interface this is clearly stated. 3.5 Colour and marking Marking of the product shall be in accordance with 2.6.2

40、 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.
