Foreword This ETSI Standard (ES) has been produced by ETSI Technical Committee Transmission and Multiplexing (TM). ETSI ETSI ES 202 319 V1.1.1 (2004-06) 5 1 Scope The present docume

14、nt specifies requirements of simplex and duplex cables for use in patchcord applications to be used in single mode optical fibre telecommunication systems. The scope covers the establishment of minimum uniform requirements for the following aspects: optical, environmental and mechanical properties;

15、test conditions; acceptance criteria. Reliability aspects of cables for use in patchcords are not covered by the present document. Some users may have additional specific requirements, such as a need to verify performance at lower temperatures. These users should specify connectors conforming to the

16、 basic ETSI performance standard, plus additional tests or more severe test conditions. Test methods are in accordance with relevant parts of IEC series. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document.

23、 semi-tight buffer may be filled. cable assembly or patchcord: combination of cable(s) and connector(s) with specified performance, used as a single unit intended to be a part of an optical cabling link sheath: overall protection of the cable strength members: tensile and/or anti-buckling protection

24、 of the fibre NOTE: This member may be either metallic or non-metallic and may be located in the cable core and/or under the sheath and/or in the sheath. 3.2 Symbols For the purposes of the present document, the following symbols apply: C Celsius dB deciBel h hourJ joule kg kilogramme km kilometre m

25、 meter mm millimetre N Newton nm nanometre4 Details, measurements and performance requirements Generally optical cables comprise several elements or individual constituents, depending on the cable design which takes into account the cable application, operating environment and assembling processes,

26、and the need to protect the fibre during terminating with connectors and handling. Mechanical and ageing tests are to ensure stability of optical performance, therefore optical tests shall be performed before, during and after the mechanical and ageing tests as applicable. All measurements shall be

27、carried out under normal room conditions, unless otherwise stated. Before the attenuation and return loss measurement, careful cleaning of the connectors in accordance with manufacturers instructions is necessary. The measured results shall be reported in graphical or table format with the limits sp

28、ecified in the standard distinctly shown in the table at the same wavelengths as specified in the present document. All optical tests shall be carried out in the 1 310 nm, 1 550 nm and the 1 625 nm window unless otherwise stated. Light sources with peak wavelengths of 1 310 nm 30 nm, 1 550 nm 30 nm
