DIN EN 61753-1-3:2015-03

This part of IEC 61753 defines the minimum initial performance, test and measurement requirements and the severities requirements which a connector or cable assembly with single-mode fibres needs to satisfy in order to be categorized as meeting IEC Category I (industrial environment). Category I is an additional environmental category to C, U, O and E already described in IEC 61753-1. Category I is based on the MICE Table described in ISO/IEC 24702. The performance tests evaluate the product for two basic acceptance criteria: mechanical integrity and optical transmission requirements, by simulating the effects of exposure to the environment in which it will be installed, simulating installation and intervention conditions, and evaluating all specified features of the product. The defined performance test procedures simulate the situation in a mated condition under use in an industrial environment. It is not the intention to simulate the situation: - when being mated or demated; - during the assembling of the connector; - during transportation and storage of the connector. Reliability tests for life time expectations are not covered by this standard. The standard gives the minimum requirements, details and testing severities für 20 different tests. Thus, the standard provides investment security for manufacturers and users as well as defined testing information for testing laboratories and manufacturers. The responsible committee is DKE/UK 412.7 "LWL-Verbindungstechnik und passive optische Komponenten" ("Fibre optic interconnecting devices and passive optical components") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
