S-QD4A31M05-CD-4 module converts 8 channels of 50Gb/s (PAM4) electrical input data to 4 channels of parallel optical signals, each capable of 100Gb/s operation for an aggregate data rate of 400Gb/s. Reversely, on the receiverside, the module converts 4 channels of parallel optical signals of 100Gb/s each channel for an aggregate data rate of 400Gb/s into 8 channels of 50Gb/s (PAM4) electrical output data.An optical fiber cable with an MTP/MPO-12 connector can be plugged into the Springtek 400Gb/s QSFP-DD DR4 module receptacle.Proper alignment is ensured by the guide pins inside the receptacle.The cable usually cannot be twisted for proper channel to channel alignment.Electrical connection is achieved through an QSFP-DD MSA-compliant edge type connector.The product is designed with form factor, optical/electrical connection and digital diagnostic interface according to the QSFP-DD Multi-Source Agreement FeaturesQSFP-DD MSA compliantParallel 4 Optical LanesIEEE 802.3bs 400G-DR4 Specification compliantUp to 500m transmission on single mode fiber (SMF) with FECOperating case temperature: 0 to 70oC8x53.125Gb/s electrical interface(400GAUI-8)Data Rate 106.25Gbps (PAM4) per channel.Maximum power consumption 12WMPO-12 connectorRoHS compliantApplications400G EthernetInfiniband interconnectsData Center Enterprise networking Absolute Maximum RatingsIt hasto be noted that the operation in excess of any individual absolute maximum ratings might cause permanent damage to this module.ParameterSymbolMinTypMaxUnitPower Supply VoltageVcc-0.5 3.6VStorage Temperature RangeTs-40 85°COperating Case TemperatureTo0 70°CRelative Humidity (non-condensation)RH0 85% Recommended Operating Conditions and Power Supply RequirementsParameterSymbolMinTypicalMaxUnitsNotesOperating Case TemperatureTOP0 70degC Power Supply VoltageVCC3.1353.33.465V Data Rate, each Lane  26.5625 GBdPAM4Data Rate Accuracy -100 100ppm Pre-FEC Bit Error Ratio   2.4x10-4  Post-FEC Bit Error Ratio   1x10-12 1Link DistanceD0.002 500m2 Electrical CharacteristicsThe following electrical characteristics are defined over the Recommended Operating Environment unless otherwise specified.ParameterTest ointMinTypicalMaxUnitsNotesPower Consumption   12W Supply CurrentIcc  3.64A Transmitter (each Lane)Signaling Rate, each LaneTP126.5625 ± 100 ppmGBd Differential pk-pk Input Voltage ToleranceMismatchTP1a900  mVpp1Differential TerminationTP1  10% Differential Input Return LossTP1IEEE 802.3-2015Equation (83E-5)  dB Differential to Common ModeInput Return LossTP1IEEE 802.3-2015Equation (83E-6)  dB Module Stressed Input TestTP1aSee IEEE 802.3bs120E.3.4.1 2Single-ended VoltageTolerance Range (Min)TP1a-0.4 to 3.3V Near-end Eye Height, DifferentialTP1-350 2850mV3Receiver (each Lane)Far-end Eye Height, DifferentialTP426.5625 ± 100 ppmGBd Differential Peak-to-PeakOutput VoltageTP4  900mVpp AC Common Mode Output Voltage (Vcm)TP4  17.5mV Differential TerminationMismatchTP4  10% Differential Output Return Loss TP4IEEE 802.3-2015Equation(83E-2)    Common to Differential Mode ConversionReturn LossTP4IEEE 802.3-2015Equation(83E-3)    Transition Time, 20% to 80% TP49.5  ps Near-end Eye Symmetry Mask Width(ESMW)TP4 0.265 UI Near-end Eye Height,DifferentialTP470  mV Far-end Eye Symmetry Mask Width(ESMW)TP4 0.2 UI Far-end Eye Height,DifferentialTP430  mV Far-end Pre-cursor ISI RatioTP4-4.5 2.5% Common Mode Output Voltage (Vcm)TP4-350 2850mV3Notes:1.
