Notes:
1. GND is the symbol for signal supply (power) common for the QSFP+ AOC. All are common within the
QSFP+ AOC and all device voltages are referenced to this potential unless otherwise noted. Connect these
directly to the host board signal-common ground plane
2. Vcc Rx, Vcc1 and Vcc Tx are the receiver and transmitter power supplies and shall be applied concurrently.
