Note1. As the total average launch power limit has to be met, not all of the lanes can operate at the maximum average launch power ,each lane.
Note2. Average launch power, each lane(min) is informative and not the principal indicator of signal strength. A transmitter with launch power below this value can not be compliant: however, a value above this does not ensure compliance.
Note3. Even if the TDECQ<1.4dB for an extinction ratio of >=4.5dB or TDECQ<1.3dB for an extinction ratio of <4.5dB, the OMA outer (min) must exceed this value.
Note4. Transmitter reflectance is defined looking into the transmitter.
Note5. The receiver shall be able to tolerate, without damage, continuous exposure to an optical input signal having this average power level.
Note6. Average receiver power, each lane(min) is informative and not the principal indicator of signal strength. A received power below this value cannot be compliant; however, a value above this does not ensure compliance.
Note7. Measured with conformance test signal at TP3 for the BER specified in 《100G-FR and 100G-LR1
Technical Specifications Rev 2.0》
Note8. These test conditions are for measuring stressed receiver sensitivity. They are not characteristics of the receiver.

Note1.GND is the symbol for signal and supply (power) common for QSFP28 modules. 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.
Note2. Vcc Rx, Vcc1 and Vcc Tx are the receiver and transmitter power suppliers and shall be applied concurrently. Vcc Rx, Vcc1 and Vcc Tx may be internally connected within the QSFP28 transceiver module in any combination. The connector pins are each rated for a maximum current of 1000mA.
Note3.Timing for SCL, SDA and ModSelL shall comply with the common management interface document SFF-8636 and SFF-8679.
Note4.The QSFP28 module must support hardware reset operation.
Note5.Two Multi-Purpose PIN for supporting Tx_DIS and Rx_LOS function in the 100G QSFP28 module.The IIC interface must function normally when the QSFP28 module is in the LP mode.
