49 1 Scope
50 1.1 Product definition
51 This standard contains the initial, start of life dimensional, optical, mechanical and environmental
52 performance requirements which an assembled single-mode patch cord must meet in order for it to be
53 categorised as an EN standard product.
54 Since different variants and grades of performance are permitted, product marking details are given in 3.5
55 and Clause 4.
56 1.2 Intermateability of the plugs
57 Although all products conforming to the requirements of this standard will intermate, the resulting level of
58 random attenuation performance will only be ensured in accordance with Table 1. The intention is that this
59 will be true irrespective of the manufacturing source(s) of the product.
60 When intermating plug variants having different attenuation grades as specified in EN 61755-1, the resulting
61 level of attenuation cannot be assured to be any better than the worst attenuation grade.
62 The intermating of a grade C plug with a grade B plug will result in a grade C level of random attenuation
63 performance.

66 1.3 Operating environment
67 The tests selected combined with the severities and durations are representative of an EN 61753-1
68 Category C environment.
69 1.4 Reliability
70 Whilst the anticipated service life expectancy of the product in this environment is 20 years, compliance with
71 this standard does not guarantee the reliability of the product. This should be predicted using a recognised
72 reliability assessment programme.
73 1.5 Quality assurance
74 Compliance with this standard does not guarantee the manufacturing consistency of the product. This should
75 be maintained using a recognised quality assurance programme.

80 3 Description
81 For the purpose of this document a patch cord is defined as a short length of cable with connector plugs
82 assembled at both cable ends. Typical length (but not limited to) is 1 m to 10 m, measured from tip to tip at
83 the extremes. Patch cords are installed in mechanical protected locations (inside cabinets, distribution
84 frames and enclosures).
85 The document also applies to work area cords which are typically more ruggedised (larger diameter) and
86 used in mechanical less protected locations. For the purpose of this document both patch cords and work
87 area cords are called patch cords.

88 3.1 Plug
89 The plug features a cylindrical ferrule. It has a single male key which is used to limit and may be used to
90 orientate, the relative rotation between mated connectors.
91 A cover (dust cap) to protect the ferrule end faces when the connectors are in the unmated condition shall be
92 provided.
93 The plug shall meet the relevant product specification as listed in Table 2.
