Foreword This Tec
15、hnical Specification (TS) has been produced by ETSI Technical Committee Transmission and Multiplexing (TM). The present document is a revision of ES 200 671. ETSI ETSI TS 100 671 V1.3.1 (2004-07) 5 1 Scope The present document specifies requirements of connector sets to be used in single-mode optica
16、l fibre telecommunication systems and it applies only to pigtailed connectors, not patchcords. The scope covers the establishment of minimum uniform requirements for the following aspects: - optical, environmental and mechanical properties; - test conditions; - acceptance criteria. Reliability aspec
17、ts of connector sets 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 basic ETSI performance standard, plus additional tests or more sever
18、e test conditions. Connectors for different applications which fall within the scope of the present document have common environmental and mechanical stability requirements, but there are three grades of attenuation requirement and three grades of return loss. The attenuation grades are designated B
19、,C and D The return loss grades are designated 1, 2 and 3 Test methods are in accordance with IEC 61300 series 2. For a definition of a connector set, see clause 3.1 of the present document. 2 References The following documents contain provisions which, through reference in this text, constitute pro
20、visions of the present document. References are either specific (identified by date of publication and/or edition number or version number) or non-specific. For a specific reference, subsequent revisions do not apply. For a non-specific reference, the latest version applies. Referenced documents whi
