30、an optical fibre within a connector and which is both removable from and replaceable in the connector. A specific terminus may be used in a wide variety of connector styles (e.g. circular, rectangular, rack and panel, hybrid, etc.) which may be qualified under other specification systems (e.g. speci
31、fications for electrical connectors) 1.3.2 terminus set the two mateable termini. Generally, a set consists of a terminus pin and a terminus socket 1.3.3 mechanically intermateable termini termini which are capable of being mechanically mated. Performance or intermountability are not requirements fo
32、r intermateabilityEN61269-1:1997 4 BSI 02-1999 1.3.4 interchangeable termini termini which meet the same assessed performance specification and are intermountable. Interchangeability applies to a terminus set only since individual termini are not necessarily intermateable 1.3.5 intermountable termin
33、i termini which have identical mounting parameters. Intermateability or interchangeability are not requirements for intermountability 1.3.6 termini control dimensions those termini dimensions which control intermateability and intermountability 1.4 Abbreviations 2 Requirements 2.1 Qualification Comp
34、onents covered by this specification shall be authorized by the NSI for listing on the QPL under the qualification procedure in accordance with11.3.1 of QC001002. 2.2 Classification Termini are classified, either totally or in part, by the following categories: type; arrangement; style; variant; cli
35、matic category; environmental category; assessment level. SeeTable 1 for an example of a complete terminus-set classification. 2.2.1 Type Terminus sets shall be classified by type. Type is defined by three elements the type name, the configuration, and the control dimensions. Examples of terminus-se
36、t names: FOTS, gauge 8; subminiature D, gauge 16. Examples of terminus-set configurations: pin/socket; pin/pin.

37、hall be classified by arrangement. Arrangement category defines the delivered terminus-set form. Examples of arrangements: kit; pigtail. 2.2.3 Style Terminus sets shall be classified by style. Style is defined by the fibre retention technology, the cable retention technology (where applicable), the
38、optical coupling technology, and the alignment technology. Examples of fibre retention technologies: adhesive; crimp. Examples of cable retention technologies (whereapplicable): adhesive; crimp. Examples of optical coupling technologies: non-butting; butting; expanded beam. Examples of alignment tec
39、hnologies: clearance fit; resilient bushing; resilient tip; spherical. 2.2.4 Variant Termini shall be classified by variant. The variant classification consists of the variant, identification number (see2.6.1). Type Name: FOTS, Gauge 8 Configuration: pin/socket Control dimensions: pin; socket; see F
