Product Description

100G QSFP28 ZR4 80KM Transceiver Module
LAQ28-ZR4

Product Description

Link-all 's LAQ28-ZR4 is a 100Gb/s transceiver module designed for optical communication applications compliant to 100GBASE-ZR4 standard. The module converts 4 input channels of 25Gb/s electrical data to 4 channels of LAN WDM optical signals and then multiplexes them into a single channel for  100Gb/s optical transmission. Reversely on the receiver side, the module de-multiplexes a 100Gb/s optical input into 4 channels of LAN WDM optical signals and then converts them to 4 output channels of electrical data. The central wavelengths of the 4 LAN WDM channels are 1295.56, 1300.05, 1304.58 and 1309. 14 nm as members  of  the  LAN  WDM  wavelength  grid  defined  in  IEEE  802.3ba.  The  high  performance  EML transmitters and high sensitivity SOA+PIN receivers provide superior performance for 100Gigabit Ethernet applications up to 80km with FEC.
The  product  is  designed with form factor,  optical/electrical  connection  and  digital  diagnostic  interface according to the  QSFP+  Multi-Source Agreement  (MSA).  It  has  been  designed  to  meet the  harshest external operating conditions including temperature, humidity and EMI interference.

Product Features
QSFP28 MSA compliant
Hot pluggable 38 pin electrical interface

Transceiver Block Diagrams


ModSelL:
The 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 modules on a single 2-wire interface bus. When the ModSelL is "High", the module shall not respond to or acknowledge any 2-wire interface communication from the host. ModSelL signal input node shall be biased to the "High" state in the module.
In order to avoid conflicts, the  host system shall not attempt 2-wire interface communications within the ModSelL de-assert time after any modules are deselected. Similarly, the host shall wait at least for the period of the  ModSelL  assert  time  before  communicating  with  the  newly  selected  module.  The  assertion  and de-asserting periods of different modules may overlap as long as the above timing requirements are met.
ResetL:
The ResetL pin shall be pulled to Vcc in the module. A low level on the  ResetL pin for longer than the minimum pulse length (t_Reset_init) initiates a complete module reset, returning all user module settings to their default state. Module Reset Assert Time (t_init) starts on the rising edge after the low level on the ResetL pin is released. During the execution of a reset (t_init) the host shall disregard all status bits until the module indicates a completion of the reset interrupt. The module indicates this by asserting "low" an IntL signal with the Data_Not_Ready bit negated. Note that on power up (including hot insertion) the module should post this completion of reset interrupt without requiring a reset.
LPMode:
The LPMode pin shall be pulled up to Vcc in the module. The pin is a hardware control used to put modules into a low power mode when high. By using the LPMode pin and a combination of the Power override, Power_set and High_Power_Class_Enable software control bits (Address A0h, byte 93 bits 0, 1,2).
ModPrsL:
ModPrsL is pulled up to Vcc_Host on the host board and grounded in the module. The ModPrsL is asserted "Low" when inserted and deasserted "High" when the module is physically absent from the host connector.
IntL:
IntL is an output pin. When IntL is "Low", it 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 shall be  pulled to  host supply voltage on the  host board. The  INTL  pin  is deasserted "High" after completion of reset, when byte 2 bit 0 (Data Not Ready) is read with a value of '0' and the flag field is read (see SFF-8636).
