It provides increased port density and total system cost savings. The QSFP28 full-duplex optical module offers 4 independent transmit and receive channels,Website:http://www.dwdmsfp.net, each capable of 25Gb/s operation for an aggregate data rate of 100Gb/s on 2km of single mode fiber.An optical fiber ribbon cable with an MTP/MPO connector can be plugged into the QSFP28 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 MSA-compliant 38-pin edge type connector. The module operates with single +3.3V power supply. LVCMOS/LVTTL global control signals, such as Module Present, Reset, Interrupt and Low Power Mode, are available with the modules. A 2-wire serial interface is available to send and receive more complex control signals, and to receive digital diagnostic information. Individual channels can be addressed and unused channels can be shut down for maximum design flexibility. The product is designed with form factor, optical/electrical connection and digital diagnostic interface according to the QSFP28 Multi-Source Agreement (MSA). It has been designed to meet the harshest external operating conditions including temperature, humidity and EMI interference. The module can be managed through the I2C two-wire serial interface.2. Functional DescriptionThis product is a QSFP28 parallel single mode optical transceiver with an MTP/MPO fiber ribbon connector. 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 receiver module outputs electrical signals are also voltage compatible with Common Mode Logic (CML) levels. All data signals are differential and support a data rates up to 25Gb/s per channel. Figure 1 shows the functional block diagram of this product.A single +3.3V power supply is required to power up the module. Both power supply pins VccTx and VccRx are internally connected and should be applied concurrently. Per MSA the module offers 7 low speed hardware control pins (including the 2-wire serial interface): ModSelL, SCL, SDA, ResetL, LPMode, ModPrsL and IntL.Module Select (ModSelL) is an input pin. When held low by the host, the module responds to 2-wire serial communication commands. The ModSelL allows the use of multiple QSFP28 modules on a single 2-wire interface bus – individual ModSelL lines for each QSFP28 module must be used.Serial Clock (SCL) and Serial Data (SDA) are required for the 2-wire serial bus communication interface and enable the host to access the QSFP28 memory map.The ResetL pin enables a complete module reset, returning module settings to their default state, when a low level on the ResetL pin is held for longer than the minimum pulse length. During the execution of a reset the host shall disregard all status bits until the module indicates a completion of the reset interrupt. The module indicates this by posting an IntL (Interrupt) signal with the Data_Not_Ready bit negated in the memory map. Note that on power up (including hot insertion) the module should post this completion of reset interrupt without requiring a reset.Low Power Mode (LPMode) pin is used to set the maximum power consumption for the module in order to protect hosts that are not capable of cooling higher power modules, should such modules be accidentally inserted.Module Present (ModPrsL) is a signal local to the host board which, in the absence of a module, is normally pulled up to the host Vcc. When a module is inserted into the connector, it completes the path to ground through a resistor on the host board and asserts the signal. ModPrsL then indicates a module is present by setting ModPrsL to a "Low" state.Interrupt (IntL) is an output pin. Low indicates a possible module operational fault or a status critical to the host system. The host identifies the source of the interrupt using the 2-wire serial interface. The IntL pin is an open collector output and must be pulled to the Host Vcc voltage on the Host board.Optical CharacteristicsAll parameters are specified under the recommended operating conditions with PRBS31 data pattern unless otherwise specified.Parameter Symbol Min Typical Max Units Notes TransmitterCenter WavelengthλC129513101325nmSide Mode Suppression RatioSMSR30dBTotal Average Launch PowerPT8.0dBmAverage Launch Power, each LanePAVG-5.52.0dBmOptical Modulation Amplitude (OMA), each LanePOMA-3.52.2dBm1Difference in Launch Power between any Two Lanes (OMA)Ptx,diff5dBLaunch Power in OMA minus Transmitter and Dispersion Penalty (TDP), each Lane-4.3dBmTDP, each LaneTDP2.9dBExtinction RatioER3.5dBRelative Intensity NoiseRIN-128dB/HzOptical Return Loss ToleranceTOL20dBTransmitter ReflectanceRT-12dBAverage Launch Power OFF Transmitter, each LanePoff-30dBmTransmitter Eye Mask Definition {X1, X2, X3, Y1, Y2, Y3}{0.31, 0.4, 0.45, 0.34, 0.38, 0.4}2ReceiverCenter WavelengthλC129513101325nmDamage Threshold, each LaneTHd4.5dBm3Average Receive Power, each Lane-10.22.0dBmReceive Power (OMA), each Lane2.2dBmReceiver Sensitivity (OMA), each LaneSEN1-9.0dBm4Receiver Sensitivity (OMA), each LaneSEN2-12.0dBm5Receiver ReflectanceRR-26dBDifference in Receive Power between any Two Lanes (OMA)Prx,diff5.5dBLOS AssertLOSA-20dBmLOS DeassertLOSD-18dBmLOS HysteresisLOSH0.5dBReceiver Electrical 3 dB upper Cutoff Frequency, each LaneFc31GHzNotes:1.
