![]() ![]() Most popular MPO connectors have 8, 12, 16, or 24 pins. While this approach works well for duplex applications, it is not suggested for parallel 8-fiber 40 and 100 Gigabit applications.Įach MPO fiber optic cable assembly must specify a type and gender of the MPO connectors. Method C MPO patch cables utilize a key up connector on one end and a key down connector on the other, but the flip occurs within the cable itself, where each pair of fibers is flipped so that the fiber in Position 1 arrives at Position 2 and the fiber in Position 2 arrives at Position 1. Method B utilizes straight A-B patch cords on both ends for duplex applications. Method B MPO patch cables employ key up connectors on both ends to produce the transceiver-receiver flip, such that the fiber in Position 1 ends up in Position 12, the fiber in Position 2 ends up in Position 11, and so on. When employing Method A for duplex applications, one end of the patch cord must have the transceiver-receiver flipped. Method A MPO patch cables employ a key up connection on one end and a key down connector on the other, such that the fiber in Position 1 terminates in Position 1. Industry standards call for three different MPO polarity methods: Method A, Method B, and Method C. MPO polarity scheme's objective is to assure this continuous connection, which gets slightly more complicated when dealing with multi-fiber components. To ensure that data is transmitted correctly across fiber links, the transmit signal (Tx) at one end of the cable must match the equivalent receiver (Rx) at the other end. 48-144 Fiber MPO Patch Cords are available for high-density backbone applications.24-Fiber MPO Patch Cords are generally used for high-density trunk and 100G applications. ![]()
