With the field tool, the polarity of MTP® PRO cables can be changed from key up to key down. No accessories are required since both keys are pre-installed in the MTP® PRO connector. The pins can also be changed from male to female and vice versa. This operation requires pin exchangers as accessories, it can be done without opening the connector.
A big advantage of this tool is that even an unskilled and untrained technician can easily manage polarity and pin reconfiguration right in the field in a minute without needing to remove the connector housing, expose any fibers or perform any other disassembly of the connector.
