MPO-24 trunk implementations provide significant advantages for duplex and parallel implementations, providing for faster installation and better pathway efficiency. In the case of parallel applications, MPO-24 also provides the highest panel density when breakout assemblies are used. Also, MPO-24 is always a multiple of "8s" and "12s" (i.e., 24, 48, 72), but MPO-8s are not always multiples of "12" or "24" (i.e., 8, 16, 32, 40, 56). DUPLEX, PARALLEL OR BOTH? Data centers going forward will likely be a mix of duplex and parallel systems. Duplex transmission has a single-lane, or serial architecture, that can support data rates of 10 to 40 Gb/s. In a duplex system, one fiber is used to transmit and the other to receive data. Parallel transmission utilizes multiple lanes (fibers) that can support 40 Gb/s rates and beyond. This means that parallel architectures require multiple fibers to transmit and receive data. For comparison, Figures 4 and 5 show different ways of deploying these architectures based on eight fiber duplex and parallel solutions respectively. There are a lot of different options available today when deploying these higher speeds, which is why ICT designers and installers FIGURE 3: Shows the different MPO options and application benefits.
