Overview

This part of IEC 61753 defines the minimum initial test and measurement requirements and severities which single-mode fibre optic connectors terminated as a pigtail or a patchcord satisfy in order to be categorised as meeting the IEC standard category OP+ (extended outdoor protected environment), as defined in IEC 61753-1. Performance standards define the requirements for standardized optical performance under specified conditions. Each standard contains a series or set of tests and measurements with clearly specified conditions, test severities, and acceptance/rejection criteria. The test series, which are generally related to an operating environment or performance category, are intended to be performed on a one-off basis to demonstrate that a product is capable of meeting the requirements of a specific application, market segment, or user group. The following parts of this document specify test series that constitute the respective operating environment or performance category and have been standardized for international application. There are no restrictions on the scope of application of the document. The standard differs from DIN EN 61753-021-6:2008-07 as follows: a) updated environmental category (from O to OP+), tests and their severities according to IEC 61753-1:2018; b) removed the copyright notice as it is no longer needed; c) changed title and scope to remove restrictions on attenuation and return loss grades; d) changed the term and definitions of the different types of test samples (pigtail test samples and patchcord test samples) used in the various tests to avoid confusion; e) removed the term and definition for small form factor (SFF) connectors as it is no longer used in the document; f) the naming conventions for fibers have been updated in accordance with the latest revision of IEC 60793-2, and specifications for B-657 fibers have been added; g) added all the attenuation and return loss grades defined in IEC 61753-1; h) removed the static side load test; i) removed the need to perform all tests sequentially to align with other performance standards; j) added provisions for rectangular ferrule connectors; k) added Annex B for visual examination of the outer cable sheath movement of reinforced cables as an additional requirement for change of temperature, cable retention and flexing of the strain relief tests. The application of this document increases investment security for manufacturers and users, provides test laboratories and manufacturers with defined test specifications, and ensures compatibility across manufacturers.
