Major OEMs (Dell, HPE, Edge-Core) use the BCM84888 in fanless or low-noise switches. Because the chip sips power, manufacturers can put 4 to 8 ports of 10GBase-T on a switch without needing a screaming 40mm fan.
To appreciate the BCM84886, one must understand the problems it solves. As data speeds increase, the physical channel (the copper trace on a board or the copper cable) acts as a filter, distorting the signal. This distortion causes Inter-Symbol Interference (ISI), making the data unreadable at the receiving end. bcm84886
