Notes:
- Vcm is generated by the Specification includes effects of ground offset voltage.
- From 250MHz to
- The receiver shall be able to tolerate, without damage, continuous exposure to a modulated optical inputsignal having this power level on one lane. The receiver does not have to operate correctly at this input power.
- Measured with conformance test signal at receiver input for BER = 1×10-12.
- Vertical eye closure penalty, stressed eye J2 jitter, and stressed eye J9 jitter are test conditions for measuring stressed receiver sensitivity. They are not characteristics of the receiver.

Note:
- GND is the symbol for signal and supply (power) common for the QSFP28 All are common within the module and all module voltages are referenced to this potential unless otherwise noted. Connect these directly to the host board signal common ground plane.
- VccRx, Vcc1 and VccTx are the receiving and transmission power suppliers and shall be applied concurrently. Recommended host board power supply filtering is shown in Figure 3 below. Vcc Rx, Vcc1 andVcc Tx may be internally connected within the module in any The connector pins are each ratedfor a maximum current of 1000mA.
