29、der 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 3.4 and Clause 4. 1.2 Intermateability of the plugs Although all products conforming to the requirements of this standard will intermate, the
30、 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. When intermating plug variants having different attenuation grades as specified in EN 61755-1, the r
31、esulting level of attenuation cannot be assured to be any better than the worst attenuation grade. The intermating of a grade C plug with a grade B plug will result in a grade C level of random attenuation performance.

32、 2 C B Plug 1 C C C B C B 1.3 Operating environment The tests selected combined with the severities and durations are representative of an EN 61753-1 category C environment. 1.4 Reliability Whilst the anticipated service life expectancy of the product in this environment is 20 years, compliance with
33、 this 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 standard does not guarantee the manufacturing consistency of the product. This should be maintained using a recog

43、 Optical interfaces for single mode non-dispersion shifted fibres General and guidance (IEC 61755-1) 3 Description This document applies to both patch cords and work area cords. A patch cord is defined as a short length of cable with connector plugs assembled at both cable ends. Typical length (but
44、not limited to) is 1 m to 10 m, measured from tip to tip at the extremes. Patch cords are installed in mechanically protected locations (inside cabinets, distribution frames and enclosures). BS EN 50377-14-1:2011 7 EN 50377-14-1:2011 Work area cords are typically more ruggedized (larger diameter) an
45、d used in mechanically less protected locations. For the purpose of this document, both patch cords and work area cords are called patch cords. 3.1 Plug The plug features a cylindrical ferrule. It has a single male key that is used to limit and may be used to orientate, the relative rotation between
46、 mated connectors. A cover (dust cap) to protect the ferrule end faces when the connectors are in the unmated condition shall be provided. The plug shall meet the relevant product specification as listed in Table 2 (most common types are listed). Table 2 Connector references Connector Reference FC E

48、ibed are left to the discretion of the manufacturer. The plug materials shall meet the relevant requirements of the product specifications listed in Table 2. The cable materials shall meet the requirements of EN 60794-2-50. 3.4 Marking Marking of the product shall be in the following order of precedence: a) identification of the cable assembly manufacturer; b) manufacturing date code: year/week; c) manufacturers part number; d) variant identification number. Provision should be taken to avoid confusion between the original cable marking and the patch cord product information. BS EN 50377-1
