AS/NZS 14763.3 was published on Friday 3rd February 2017.
With the publication of AS/NZ 14763.3:2017 fibre testing, the requirements now align with current international standards.
Key elements of change from the previous version include
- The relaxation for the optical attenuation allowance from 0.5 dB to 0.75 dB for reference to non-reference connectors for single mode
- The relaxation for the optical attenuation allowance from 0.3 dB to 0.5 dB for reference to non-reference connectors for multimode
- The removal of support for the previous three test cord referencing method
- The previous three cord referencing method had more restrictive pass/fail requirements and could produce results with apparent gains
- Introduction of the enhanced three test cord referencing method
- Enhanced three test cord referencing method has the same pass/fail numbers as the one test cord referencing method
- At time of referencing utilising the enhanced three test cord method, only one test cord is utilised to establish the reference (One test cord between the light source and the power meter).
- After reference is set, the addition and testing of the substitution cord and/or tail cord is to have a maximum attenuation of two sets of reference connectors combined (0.20 dB max multimode, 0.40 dB singlemode)
The Publication Number and Title are as follows
Information technology -- Implementation and operation of customer premises cabling -- Part 3: Testing of optical fibre cabling.
- The reference planes for the one and enhanced three cord reference methods align to the reference planes of permanent links and links defined in AS/NZS 3080 and ISO/IEC 11801
- AS/NZS 14763.3:2017 is a modified text adoption of ISO/IEC 14763-3 and as such the publication number does not contain “ISO/IEC” in its descriptor
- All modified text is informative and as such does not change the normative requirements of the standards
