20、ce details.9 EN 61753-021-6:2008 4 INTRODUCTION Performance standards define the requirements for standard optical performance under a set of specified conditions. Each standard contains a series or a set of tests and measurements with clearly stated conditions, severities and pass/fail criteria. Th
21、e series of tests, commonly referred to as an operating service environment or performance category, is intended to be run on a one-off basis to prove the products ability to satisfy the requirements of a specific application, market sector or user group. The subsequent parts of this document define
22、 those sets of tests which form each operating service environment or performance category and which have been standardized for international use. A product that has been shown to meet all the requirements of a performance standard may be declared as complying with that performance standard. Product
23、s having the same classification from one manufacturer that satisfy a performance standard will operate within the boundaries set by the performance standard. Intermateability or interchangeability of products from different suppliers (having the same classification and conforming to the same perfor
24、mance standard) can only be guaranteed when these products also meet the interface standards. Only in this condition will an equivalent level of performance be provided when they are used together (for example, in the case of optical connectors). Conformance to a performance standard is not a guaran
25、tee of lifetime assured performance or reliability. Reliability testing must be the subject of a separate test schedule, where the tests and severities selected are truly representative of the requirements of this reliability test programme. Consistency of manufacture should be maintained using a re
26、cognized Quality Assurance programme whilst the reliability of the product should be evaluated using the procedures recommended in IEC 62005. Tests and measurements should be selected from the IEC 61300 series. Where this is not possible, the required test method should be attached as an annex to th
27、e performance standard. 5 EN 61753-021-6:2008 FIBRE OPTIC INTERCONNECTING DEVICES AND PASSIVE COMPONENTS PERFORMANCE STANDARD Part 021-6: Grade B/2 single-mode fibre optic connectors for category O Uncontrolled environment 1 Scope This part of IEC 61753 defines B/2 performance levels which a singlem
