Notes:

1. GND is the symbol for single and supply(power) common for QSFP28 modules. All are common within the QSFP28 module and all module voltages are referenced to this potential otherwise noted.Connect these directly to the host board signal common ground plane.Laser output disabled on TDIS>2.0V or open,enabled on TDIS<0.8V.

2. VccRx,Vcc1 and VccTx are the receiver and transmitter power suppliers and shall be applied concurrently. Recommended host board power supply filtering is shown below.VccRx,Vcc1 and VccTx may be internally connected within the QSFP28 transceiver module in any combination.The connector pins are each rated for maximum current of 500mA.
