Fibre optic interconnecting devices and passive components performance standard – Part 031-3: Non-connectorized single-mode 1×N and 2×N non-wavelengthselective branching devices (NWBD) for Category U – Uncontrolled environment
|Publication Date:||1 December 2014|
|ICS Code (Fibres and cables):||33.180.10|
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-selec
The requirements also cover unbalanced, bidirectional, non-connectorized, single-mode, nonwavelength- 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.
