8.2.2 Front-Port Applications

The DS280BR810 has strong equalization capabilities that allow it to equalize insertion loss and extend the reach of front-port channels by 15 dB beyond the normal capabilities of the ASIC while support CAUI-4 and CR4 electrical requirements. The DS280BR810 is designed to apply gain in a linear fashion in order to support longer distances between the switch ASIC and the front-port module. A single DS280BR810 can be used to support all eight egress channels or all eight ingress channels for two 100 GbE ports. Figure 9 illustrates this configuration.
