Defines 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 standard.

This part of IEC61753 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 categoryU 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. for 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 1×2 and 2×2 devices because they are the most commonly used.
