IMPEDANCE MATCHING AND POWER SUPPLY FILTERING
Signal inputs/outputs on the GBIC transceiver modules are AC coupled and internally terminated to 75 ohms (TD+, TD-, RD+, RD-). Each
leg of the differential pair was equally matched in length. Figure 2 shows the recommended power supply filtering network.
