2. See Figure 4 below.
3. 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 atthis input power.
4. Measured with conformance test signal at receiver input for BER = 1x10-12.
5. Vertical eye closure penalty and stressed eye jitter are test conditions for measuring stressed receiversensitivity. They are not characteristics of the receiver.

ModSelL Pin
The ModSelL is an input signal that must be pulled to Vcc in the QSFP-DD module. When held low by
the host, the module responds to 2-wire serial communication commands. The ModSelL allows the useof multiple QSFP-DD modules on a single 2-wire interface bus. When ModSelL is “High”, the module
shall not respond to or acknowledge any 2-wire interface communication from the host.
In order to avoid conflicts, the host system shall not attempt 2-wire interface communications within theModSelL de-assert time after any QSFP-DD modules are deselected. Similarly, the host must wait atleast 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 Pin
The ResetL signal shall be pulled to Vcc in the module. A low level on the ResetL signal for longer thanthe minimum pulse length (t_Reset_init) (SeeTable 13 ) initiates a complete module reset, returning

all user module settings to their default state.

LPMode Pin
LPMode is an input signal. The LPMode signal shall be pulled up to Vcc in the QSFP-DD module (seeTable 2). LPMode is used in the control of the module power mode.
See CMIS Section 6.3.1.3.

ModPrsL Pin
ModPrsL must be pulled up to Vcc Host on the host board and grounded in the module. The ModPrsL isasserted “Low” when the module is inserted and deasserted “High” when the module is physicallyabsent from the host connector.

IntL Pin
IntL is an output signal. The IntL signal is an open collector output and must be pulled to Vcc Host onthe host board. When the IntL signal is asserted Low it indicates a change in module state, a possible
module operational fault or a status critical to the host system. The host identifies the source of theinterrupt using the 2-wire serial interface. The IntL signal is deasserted “High” after all set interrupt
flags are read.

Power Supply Filtering

The host board should use the power supply filtering shown in Figure3.

Figure3. Host Board Power Supply FilteringDIAGNOSTIC MONITORING INTERFACE
Digital diagnostics monitoring function is available on all CA OPTRONICS GROUP QSFP DD products. A
2-wire serial interface provides user to contact with module.
This subsection defines the Memory Map for a CMIS Module used for serial ID, digital 3 monitoring
and certain control functions. The interface is mandatory for all CMIS 4 devices. The interface has been
designed largely after the QSFP memory map. The memory 5 map has been changed in order toaccommodate 8 electrical lanes and limit the required 6 memory space. The single address approach isused as found in QSFP. Paging is used in 7 order to enable time critical interactions between host andmodule.
The structure of the memory is shown inFigure 5 . The memory space is arranged into a 10 lower,

single page, address space of 128 bytes and multiple upper address space pages. 11 This structure
supports a flat 256 byte memory for passive copper cables and permits 12 timely access to addresses in
the lower page, e.g. Flags and Monitors. Less time critical 13 entries, e.g. serial ID information andthreshold settings, are available with the Page 14 Select function. The structure also provides address
expansion by adding additional upper 15 pages as needed. Upper pages 00-02 all contain static,

non-volatile advertising 16 registers. Upper page 01 provides revision codes and advertising registers
that indicate 17 the capabilities of the module. Upper page 02 provides thresholds for monitored 18functions. Upper page 03 provides a user read/write space. The lower page and upper page 19 00 arerequired for passive copper cables and are always implemented. In addition, upper 20 pages 1, 2 andbank 0 pages 10h and 11h are required for active modules. See

CMIS Document Table 40

for 21

details regarding the implementation of optional upper pages and the bank pages. Bank 22 pages areprovided to provide the ability to support modules with more than 8 lanes. Bank 23 0 provides
lane-specific registers for the lower 8 lanes. Each additional bank provides 24 support for an additional 8lanes. Reserved bytes are for future use and shall not be 25 used and shall be set to 0. Otherorganizations shall contact the managing organization 26 or the editor of this document to request
allocations of registers. The use of custom 27 bytes is not restricted and may be vendor defined. The useof registers defined as custom 28 may be subject to additional agreements between module users andvendors.
