Proper polarization connectivity in MTP system
The following part illustrates how the components in MTP system are used together to maintain the proper polarization connectivity, which are defined by TIA standards.
Method A: the connectivity Method A is shown in the following picture. A type-A trunk cable connects a MTP module on each side of the link. In Method A, two types of patch cords are used to correct the polarity. The patch cable on the left is standard duplex A-to-B type, while on the right a duplex A-to-A type patch cable is employed.
Method B: in connectivity Method B, a Type B truck cable is used to connect the two modules on each side of the link. As mentioned, the fiber positions of Type B cable are reversed at each end. Therefore standard A-to-B type duplex patch cables are used on both sided.
Method C: the pair-reversed trunk cable is used in Method C connectivity to connect the MTP modules one each side of the link. Patch cords at both ends are the standard duplex A-to-B type.
