Product Description
The Link-all's LAQS-LR4Mis a Four-Channel, Pluggable, Parallel, Fiber-Optic QSFP+ Transceiver for InfiniBand
QDR/DDR/SDR, 10G/8G/4G/2G fiber channel, PCIe and SAS Applications. The QSFP full-duplex optical module offers
4 independent transmit and receive channels, each capable of 10.3Gbps operation for an aggregate data rate of
40Gbps 10km using single mode fiber. These modules are designed to operate over single mode fiber systems using   1310nm DFB laser array. An optical fiber ribbon cable with an MPO/MTPTM connector can be plugged into the QSFP  module receptacle. QSFP+ PSM LR4 is one kind of parallel transceiver which provides increased port density and total
system cost savings.

Diagnostic Monitoring  Interface
Digital diagnostics monitoring function is available on all QSFP+ module. A 2-wire serial interface provides user to contact with module. The structure of the memory is shown in flowing. The memory space is arranged into a lower, single page, address space of 128 bytes and multiple upper address space pages. This structure permits timely access to addresses in the lower page, such as Interrupt Flags and Monitors. Less time critical time entries, such as serial ID information and threshold settings, are available with the Page Select function. The interface address used is A0xh and is mainly used for time critical data like interrupt handling in order to enable a one-time-read for all data related to an interrupt situation. After an interrupt, IntL has been asserted, the host can read out the flag field to determine the affected channel and type of flag.

a +/- 3 dB total accuracy.


ModSelL Pin
The ModSelL is an input pin. When held low by the host, the module responds to 2-wi re serial communication
commands. The ModSelL allows the use of multiple QSFP modules on a single 2-wire interface bus. When the
ModSelL is  "High  ", the module will not respond to any 2-wire interface communication from the host. ModSelL has
an internal pull-up in the module.
ResetL Pin
Reset. LPMode_ Reset has an internal pull-up in the module. A low level on the Reset L pin for longer than the
minimum pulse length (t_Reset_i nit) 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 Reset L 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 posting an IntL signal with the Data_Not_Ready bit
negated. Note that on power up (including hot insertion) the module will post this completion of reset interrupt
without requiring a reset.
LPMode Pin
Link-all's LAQS-LR4M operate in the low power mode (less than 1.5 W power consumption) This pin active high will
decrease power consumption to less than 1W.
ModPrsL Pin
Mod PrsL is pulled up to Vcc on the host board and grounded in the module. The Mod PrsL is asserted  " Low"  when the module is inserted and deasserted  "High  "  when the module is physically absent from the host connector.
IntL Pin
IntL is an output pin. When  "Low" , it indicates a possible module operational fault or a status critical to the host    system. The host identifies the source of the interrupt by using the 2-wire serial interface. The IntL pin is an open
collector output and must be pulled up to Vcc on the host board.

Notes:
1. GND is the symbol for single and supply(power) common for QSFP modules, All are common within the QSFP module and all module voltages are referenced to this potential otherwise noted. Connect these   directly to the host board signal common ground plane. Laser output disabled on TDIS >2.0V or open,   enabled on TDIS <0.8V.
2.VccRx, Vcc1 and VccTx are the receiver and transmitter power suppliers and shall be applied
concurrently. Recommended host board power supply filtering is shown below. VccRx, Vcc1 and VccTx may be internally connected within the QSFP transceiver module in any combination. The connector
pins are each rated for maximum current of 500mA.
