Fibre optic interconnecting devices and passive components. Performance standard - Non-connectorized single-mode 1×N and 2×N non-wavelength-selective branching devices for Category U. Uncontrolled environment1 Scope 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 requirements of this standard. The requirements cover balanced bidirectional non connectorized single mode 1 N and 2 N non wavelength selective branching devices for use in an IEC category U environment (N is the number of
