DIN EN 61753-031-6:2015-07

This part of IEC 61753 contains the minimum initial tests and measurement requirements and severities which a non-wavelength selective branching device (NWBD) should satisfy in order to be categorized as meeting the requirement of this IEC standard. The requirements cover balanced bidirectional non-connectorized single-mode 1xN and 2xN non wavelength-selective branching devices for use in an IEC Category C environment (N is the number of branching ports), especially but not exclusively used for PON application. For balanced NWBD two attenuation and uniformity performance classes are considered: - class A (premium class) which meets more restrictive requirements (for example, for extended reach PON application) and class B (standard class) for standard application (for example, normal reach PON application). The requirements also cover unbalanced bidirectional non-connectorized single-mode, non-wavelength-selective branching devices; however, the specifications of unbalanced branching devices are limited to 1x2 and 2x2 devices because they are the most commonly used. The standard contains the test plan for the operational behaviour. The standard thus offers investment security for manufacturers and users and provides testing laboratories and manufacturers with defined information for testing. The responsible committee is Subcommittee 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.
