Abstract

IEC 61753-031-6:2014 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 requirements of this standard. The requirements cover balanced bidirectional non-connectorized single-mode 1xN and 2xN non-wavelength-selective branching devices for use in an IEC category O 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 (i.e. for extended reach PON application) and - class B (standard class) for standard application (i.e. 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. This second edition of IEC 61753-031-6 cancels and replaces the first edition published in 2008 and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - deletion of the Introduction; - an updated and extended scope to reflect an introduction of two attenuation and uniformity performance classes for balanced NWBD instead of branching device technologies on the market; - an updated list of normative references; - a more simplified introduction to the two types of spectral bands; - Clause 5, Performance requirements, has been updated and extended to reflect the introduction of two attenuation and uniformity performance classes for balanced NWBD; - simplified test items to exclude tests for damp heat (steady state) and impact for performance requirements; - Annex A has been changed to introduce the calculated and minimum requirements for attenuation and uniformity. Keywords: non-wavelength selective branching device (NWBD), IEC category O environment
