1. General Description
This  product  is a transceiver  module designed for  10km  optical communication applications. The   module  incorporates  one  channel  optical  signal,  on   1271/1331nm  center  wavelength, operating at   50Gbaud  data   rate.  The  transmitter   path   incorporates   an  EML Driver  and  a cooled EML together. On the receiver path, the input optical signal is coupled to a Pin photodiode detector. A  DSP based gearbox is used to convert 4x25Gbps  NRZ signals to  1x50Gbaud PAM4 signal. In additional, a 4-channel retimer and  FEC block are integrated in this DSP. The electrical interface   is  compliant  with  IEEE  802.3  and  QSFP28   MSA  in  the  transmitting  and   receiving directions, and optical  interface  is compliant to  IEEE   802.3  and  100G-LR1-10 in 100G Lambda MSA standard. The module has a maximum power consumption of 4.5 W.
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.

2.  Functional Description
This product converts the 4-channel of 100Gbps aggregated  NRZ electrical input data into one channel  of 50Gbaud PAM4 optical signal (light) on  1271/1331nm center wavelength through   a DSPbased  gearbox,  by a driven cooled  Electro-absorption  Modulated  DFB  Laser  (EML).
The  lightpropagates out of the transmitter into an SMF fiber. The receiver module accepts the 50Gbaud PAM4  optical signal input, and converts it into a 50Gbaud  PAM4 electrical signal
via a linear amplifier. And then convert the 50Gbaud  PAM4 signal into 4 channels of 25Gbps NRZ signals. Figure 1 shows the functional block diagram of this product.
A single  +3.3V  power  supply  is  required  to  power  up this  product.  Both  power  supply  pins VccTx  and VccRx  are  internally  connected and  should  be  applied concurrently. As  per  MSA specifications  the module offers seven 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, this product responds to 2-wire   serial  communication  commands.  The ModSelL  allows  the  use  of  this product  on  a   single 2-wire interface bus - individual ModSelL lines 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 memory map.
The   ResetL  pin enables a complete  reset,  returning the 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 it indicates a completion of the reset  interrupt.  The   product  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 product   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 product,   is   normally  pulled  up  to  the   host  Vcc.  When the product 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 its present by setting ModPrsL to a   "Low" state.
Interrupt  (IntL)  is  an  output  pin.    "Low"  indicates  a  possible  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.

Notes:
1.     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.
2.    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 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.

Notes:
1.    Average launch power, each lane min is informative and not the principal indicator of   signal strength. A transmitter with launch power below this value cannot be compliant; however, avalue above this does not ensure compliance.
2.     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 OMAouter (min) must exceed the minimum value specified here.
3.     Average receive power (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.
4.    The receiver shall be able to tolerate, without damage, continuous exposure to a
modulated  optical input signal having this power level on one lane. The receiver does not have to operate correctly at this input power.
5.    Receiver sensitivity (OMAouter) (max) is informative and is defined for a transmitter with
a value of SECQ up to 3.4 dB.  It should meet Equation (1), which is illustrated in Figure 4.
 

 

Where:
