Conventional cabling systems employ a single fiber connector to maintain the polarity requirement for the "B" transmit signal while the "a" receives signal. However, two alternative types of serial duplex connections are available for the duplex jumper, depending on whether the polarity method is "straight-through" routing for the "a-to-B" jumper or "cross" routing for the "a-to-a" jumper. Therefore, polarity reversal is generally required in fiber routing. However, for conventional LC fiber jumpers, polarity reversal is very limiting.
