Foreword This ETSI Standard (ES) has been produced by ETSI Technical Committee Transmission and Multiplexing (TM). ETSI 5 ETSI ES 201 792 V1.l.l (2000-08) 1 Scope The pres

12、ent document is an ETSI standard on optical patchcords with connectors for use as patchcords within optical transmission systems. The optical fibres are those described in EN 188100 9 (sectional specification) and EN 188101 lo (family specification). The considered patchcords use the cables with eit

13、her primary and secondary coating and diameter of 0,9 mm or primary, secondary and outer coating and diameter up to 33 mm. The present document specifies requirements of cables assemblies with connector sets to be used in single-mode optical fibre telecommunication systems. The scope covers the esta

14、blishment of minimum uniform requirements for the following aspects: test conditions; optical, environmental and mechanical properties; acceptance criteria. Some users may have additional specific requirements, such as a need to verify performance at lower temperatures. These users should specify pa

15、tchcords with connectors conforming to the basic ETSI performance standard, plus additional tests or more severe test conditions. Patchcords for different applications which fall within the scope of the present document have common environmental and mechanical stability requirements. Patchcords spec

16、ified according to this specification shall be assembled with connector sets already approved by I-ETS 300 671 7. Patchcords specified according to this specification shall also be assembled with single fibre cables already approved by I-ETS 300 644 SI. The outer diameter of the single fibre cable s

17、hall be up to 33 mm. Test methods are in accordance with EN 186000-1 i or IEC 61300 3 series 3. For a definition of a patchcord with connector see clause 3 of the present document. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of

26、ions covered by the present document are based on those in table 1 of EN 186005 2. There are, however, several significant differences and these are listed below. All measurements shall be carried out under normal room conditions, unless otherwise stated. Before the insertion and return loss measure

27、ment, careful cleaning in accordance with manufacturers instructions is necessary. All optical tests shall be carried out in both the 1 310 nm window and the 1 550 nm window unless otherwise stated. Light sources with peak wavelengths of 1 3 10 * 30 nm and 1 550 * 30 nm shall be used. 4.1 Attenuatio

28、n NOTE: Attenuation is referred to as “insertion loss“ in EN 186000-1 i and EN 186005 2. The two terms are interchangeable and “attenuation“ is used in the present document.
