European Standard contains the initial, start of life dimensional, optical, mechanical and environmental performance requirements that a Factory Polished Field Terminated (FPFT) single mode simplex connector set (plug adaptor plug), adaptor will meet in order for it to be categorised as an EN standard product The FPFT is designed for either fusion or mechanical splice methods The performance is specified for the mated combination between a FPFT plug and an EN standardised plug from the EN 50377 series (configuration 1) or between two FTFP plugs (configuration 2) The fibre specified inside the FPFT plug in this European Standard is standard single mode fibre with low water peak as specified as B1.3, which is field, mated to B1.3 fibre or bend insensitive single mode fibre specified as B6_a1 or B6_a2 in EN 60793-2-50 Mixing standard and bend insensitive fibres in a connection causes a considerable intrinsic attenuation due to mode field diameter mismatch These connectors are intended to be installed inside wall outlets or other fibre organisers, and are therefore considered as being in a “protected environment” and are terminated onto either 250 μm primary coated or up to 900 μm buffered fibres Since different variants and grades of performance are permitted, product marking details are given in 3.5 1.2 1.2.1 Intermateability Mechanical intermateability In order to meet mechanical performance requirements, the FPFT plug will meet the optical, environmental and mechanical requirements as stated in this European Standard and the mated plug will meet the all requirements of the relevant EN 50377 series for category C Intermateability between the FPFT plug and its standard EN 50377 counterpart can only be guaranteed when both plugs meet the same EN 50377 product specification mechanical connector interface dimensions and endface geometry requirements 1.2.2 Optical intermateability In EN 50377 product specifications, the random mated performance is calculated when the two connector plugs have been terminated with single-mode fibres using a worst case MFD The specified MFD range in fibre standards (e.g B1.3 fibres) is 8,0 μm to 10,1 μm at 310 nm, which causes 0,22 dB worst case intrinsic attenuation However, in EN 50377 product specification series, the MFD is limited to 8,9 μm to 9,5 μm at 310 nm In this European Standard, in order to achieve the random mate performance values, the total MFD range of bend insensitive fibres, e.g B6a fibres, is limited to 8,5 μm to 9,5 μm at 310 nm This causes a worst case intrinsic attenuation of 0,05 dB 1.3 Operating environment The tests selected, combined with the severities and durations, are representative of a category C environment as defined in EN 61753-1 The FPFT plugs are terminated on to 250 µm primary coated or up to 900 µm buffered fibres and are specified to be located in a protected environment 1.4 Reliability Whilst the anticipated service life expectancy of the product in this environment is 20 years, compliance 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 should be maintained using a recognised quality assurance programme BS EN

Attenuation of random mated connectors (IEC 61300-3-34) 3.1 Description General The FPFT PC or APC connector is a single position plug connector set of plug adaptor plug configuration characterised by a cylindrical, spring loaded butting ferrule and a coupling mechanism The optical alignment mechanism of the connectors is of a resilient sleeve style 3.2 Plug The plug features a cylindrical ferrule and a coupling mechanism It has a single male key that is used to limit and may be used to orientate the relative rotation between mated connectors The ferrule is factory terminated with B1.3 fibre where the MFD is limited to 8,9 µm to 9,5 µm at 310 nm and the optical interface is completed to the appropriate EN 50377 product specification The plug shall contain a mechanism / feature which allows the factory polished component to be field terminated onto the incoming fibre either by mechanical or by fusion splicing A cover (dust cap) to protect the ferrule endface when the connector is in the unmated condition shall be provided 3.3 Adaptor The adaptor has a zirconia ceramic resilient alignment sleeve Covers (dust caps) shall be provided to protect each port of the adaptor 3.4

50377-17-1:2013 21 Annex B (informative) Reference connector details B.1 General information Reference connectors might used for final production approval as part of the quality assurance procedures or for testing purposes This European Standard specifies that the fibre inside the FPFT plug is a B 1.3 type as specified in EN 60793-2-50 The FPFT plug may be terminated onto B 1.3 or B6a fibres The MFD of the used fibre might influence the measured total attenuation due to the intrinsic attenuation caused by MFD mismatches We therefore recommend a limited range of MFD to be used for the reference connector B.2 Reference connector details When reference connectors are used, the following standards and details are recommended:  IEC 61755-2-4, Fibre optic interconnecting devices and passive components — Fibre optic connector optical interfaces — Part 2-4: Connection of non-dispersion shifted single mode non-angled physically contacting fibres for reference connector application;  IEC 61755-2-5, Fibre optic interconnecting devices and passive components — Fibre optic connector optical interfaces — Part 2-5: Connection of non-dispersion shifted single mode angled polished physically contacting fibres for reference connector applications Table B.1 — Reference connector details Eccentricity of spherically polished ferrule endface < 50 µm Visual examination of fibre endface with ×200 magnification No defects in core zone Attenuation between two reference plugs at 310 nm < 0,10 dB Visual examination every mating BS EN 50377-17-1:2013 EN 50377-17-1:2013 22
