Foreword This ETSI Standard (ES) has been produced by ETSI Technical Committee Transmission and Multiplexing (TM). The present document is a revision of I-ETS 300 67 1 5. ETSI 5 ETSI ES 200 671 V1.2.1 (2000-
15、08) 1 Scope The present document specifies requirements of connector sets to be used in single-mode optical 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: - opt
16、ical, environmental and mechanical properties; - test conditions: - acceptance criteria. Reliability aspects 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
17、 specify connectors conforming to the basic ETSI performance standard, plus additional tests or more severe 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 two gr
18、ades of attenuation requirement and three grades of return loss. The attenuation grades are designated P and Q. The return loss grades are designated T, U and V. Test methods are in accordance with IEC 61300 series 2. For a definition of a connector set, see subclause 3.1 of the present document. 2

Reference plug: Type A): For qualification testing to determine the loss of connector sets when one side is a defined reference, the eccentric
31、ity of the reference connector plug (centre of fibre core to centre of ferrule) shall be 5 0,3 pm.

For these tests, the initial loss of the connector sets that are to be tested shall be less than 1,O dl3 for plugs conforming to grade P or less than
33、 0,60 dl3 for plugs conforming to grade Q. Type B): Only the fundamental mode shall propagate at the connector interface and at the detector.
