MTP®/MPO cable assemblies are prevalent in fiber networks and their quantities are growing as parallel communication increases. These assemblies introduce unique testing challenges, whether it is a standard 12f MPO to 12f MPO assembly or one of the various different fanouts and fiber count configurations. In this presentation, learn more about equipment identification and setup, as well as proper testing during production. We also explore common pitfalls and ways to identify errors and inaccuracies during the testing process. US Conec will review terminated MPO connector standards required for test leads including polarity methodologies and how configurable connector types can be used to make the test setups more versatile.
IEC-61754-7 and TIA-604-5-F (FOCIS 5)
These standards govern the intermateability of MTP/MPO connectors. Two MTP/MPO connectors should be intermateable so long as they dimensionally meet either of these standards.
Under the IEC standards, the one-row connector variant is governed under IEC-61754-7-1 and the two-row variant is governed under IEC-61754-7-2. TIA standards cover all versions under FOCIS 5.
This standard covers additional details of the MTP/MPO connector such as polarity. This standard specifies the opposing key adapter as a Type A adapter and the aligned key adapter as a Type B adapter.
This recently released standard (March 2020) provides general guidance on maintaining polarity of cables and other components within telecommunications systems.
