The International Electrotechnical Commission has released a new edition of IEC 61753-031-2. IEC 61753-031-2:2014 ed 2.0 applies to “Fibre optic interconnecting devices and passive components – Performance standard – Part 031-3: Non-connectorized single-mode 1×N and 2×N non-wavelength-selective branching devices for Category U – Uncontrolled environment”. The new edition is available for purchase on the IEC’s website.
“IEC 61753-031-2:2014(E) 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.”
