Notes:

1. The optical power is launched into SMF.
2. The receiver shall be able to tolerate, without damage, continuous exposure to an optical input signal having this average power level. The receiver does not have to operate correctly at this input power.
3. Average receive power, each lane (min) is informative and not the principal indicator of signal strength.
4. Measured with conformance test signal at TP3 using the test pattern PRBS31Q or scrambled idle for stressed receiver sensitivity for the BER= 2.4x10^-4.

Notes:

1. GND is the symbol for signal and supply (power) common for the QSFP28 module. All are common within the QSFP28 module and all module 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. Requirements defined for the host side of the Host Edge Card Connector are listed in MSA. The connector pins are each rated for a maximum current of 1000 mA.
3. Two Multi-Purpose Pin for supporting Tx_DIS and Rx_LOS function in the 100G QSFP28 ER1 BIDI module.

Module Power Supply Specification
100G QSFP28 ER1 BIDI needs power supply of 3.3V, the following figure shows the timing of the initial module turn-on in Low Power Mode, and the later transition to full power mode after the host system has enabled it via the two-wire interface. And shows the power supplies to the module and the according current values. Module power supply refer to SFF-8679 TABLE 5-6.
