The TIA 568 standard defines three primary MPO polarity methods. These methods use specific MTP® trunk cables (Type A, Type B, or Type C) and duplex patch cables (A-to-A or A-to-B). They ensure correct fiber circuit polarity.
Type A (Straight-Through) MPO Trunk Polarity Explained
Method A uses a Type A trunk cable. This cable connects MTP® modules. It requires standard A-to-B type duplex patch cables on both ends of the link. For duplex applications, Method A requires an A-A duplex patch cord at one end. This flips the transceiver-receiver from Position 1 (Tx) to Position 2 (Rx). An A-B patch cord is needed at the other end. For 40/100 Gig applications, Method A uses a Type A MPO patch cord on one end and a Type B MPO patch cord on the other end. This connects patch panel ports to transceiver ports. Only one Type B patch cord is permitted in the channel.
Type B (Cross-Over) MPO Trunk Polarity for Transceiver Matching
Method B employs a Type B trunk cable. This cable has reversed fiber positions at each end. Standard A-to-B type duplex patch cables are used on both sides. For duplex applications, Method B uses A-B duplex patch cords on both ends. No transceiver-receiver flip is needed. For 40/100 Gig applications, Method B employs Type B MPO patch cords on both ends. This connects patch panel ports to their respective ports. This method is often recommended. It uses the same patch cord type for both duplex and parallel applications.
Type C (Pair-Flipped) MPO Trunk Polarity in Specific Scenarios
Method C utilizes a pair-reversed trunk cable. This cable links MTP® modules. Similar to Method A and B, standard A-to-B type duplex patch cables are used at both ends.
