Product Features MTP/MP0 optical connector Single +3.3V power supply Hot-pluggable QSFP28 MSA form factor Up to 100m OM4 MMF Distance 4x28G Electrical Serial Interface (CEI-28G-VSR) AC coupling of CML signals Low power dissipation(Max:3.5W) Built in digital diagnostic function Operating case temperature range:0ºC to 70ºC Compliant with 100GBASE-SR4 I2C Communication Interface Applications 100GBASE-SR4 Infiniband QDR/DDR/SDR 100G Datacom connections  Standards Compliant with IEEE 802.3ba Compliant with QSFP28 MSA hardware specifications Compliant with RoHS Functional Description The 100G QSFP28 SR4 optical transceiver integrates the transmit and receive path onto one module. It converts parallel electrical input signals into parallel optical signals, by a driven Vertical Cavity Surface Emitting Laser (VCSEL) array. The transmitter module accepts electrical input signals compatible with Common Mode Logic (CML) levels. All input data signals are differential and internally terminated. The receiver module converts parallel optical input signals via a photo detector array into parallel electrical output signals. The reCML) levels. All data signals are differential and support a data rates up to 27.9525Gb/s per channel.ceiver module outputs electrical signals are also voltage compatible with Common Mode LogicOn This module features a hot-pluggable electrical interface, low power consumption, and 2-wire serial interface.Absolute Maximum Ratings  ParameterSymbolMin.Max.UnitNoteSupply VoltageVcc-0.53.6V Storage TemperatureTS-4085°C Relative HumidityRH085% Rx Damage Threshold,per LanePRdmg5.5 dBm Note: Stress in excess of the maximum absolute ratings can cause permanent damage to the transceiver.Recommended Operating ConditionsParameterSymbolMinTypMaxUnitsNoteOperating Case TemperatureTC0-+70°C Power Supply VoltageVCC3.143.33.47V Data rate  103.125112Gb/s Link Distance (OM3)   70m Link Distance (OM4)   100m Electrical Characteristics (Top=0~70ºC, Vcc=3.14~3.47V)(Tested under recommended operating conditions,unless otherwise noted)  ParameterSymbolMinTypMaxUnitNotesTransmitterSignaling rate per laneDRPL25.78125 ± 100 ppmGb/s Differential pk-pk input voltage toleranceVin,dpp  900mV Single-ended voltage toleranceVin,pp-0.35 +3.3V Module stress input test Per IEEE 802.3bm  ReceiverSignaling rate per laneDRPL25.78125 ± 100 ppmGb/s Differential data output swingVout,pp400 800mV Eye widthEw0.57  UI Vertical eye closureVEC5.5  dB Differential termination mismatchTm  10% Transition time, 20% to 80%Tr,Tf12  ps Optical Characteristics (Top=0~70ºC, Vcc=3.14~3.47V)(Tested under recommended operating conditions,unless otherwise noted)  ParameterSymbolUnitMinTypMaxNotesTransmitterSignaling rate, each laneDRplGb/s25.78125 ±100 ppm1Center Wavelengtheλnm840850860 RMS Spectral Width nm 0.6  Average launch power, each lanePavgdBm-8.4 2.4 Optical modulation amplitude, each lane (OMA)OMAdBm-6.4 3 Extinction ratioERdB2   Average Launch Power of OFF Transmitter, per LaneRINdBm  -30 Encircled FluxFLXdBm>86% at 19 um
