1 x 12 PIN Array
The optical transmitter module (see Figure 1) incorporates a 12-channel VCSEL (Vertical Cavity Surface Emitting
Laser) array, a 12-channel input buffer and laser driver, diagnostic monitors, control and bias blocks. The transmitter is designed for IEC-60825 and CDRH eye safety compliance; Class 1M out of the module. The Tx Input Buffer
provides CML compatible differential inputs (presenting
a nominal differential input impedance of 100 Ohms and
a nominal common mode impedance to signal ground
of 25 Ohms) for the high speed electrical interface that
can operate over a wide common mode range without
requiring DC blocking capacitors. For module control and
interrogation, the control interface (LVTTL compatible)
incorporates a Two Wire Serial (TWS) interface of clock
and data signals and dedicated signals for host interrupt,
module address setting and module reset. Diagnostic
monitors for VCSEL bias, light output (LOP), temperature,

upon reading the appropriate flag register. The electrical output will squelch for loss of input signal (unless
squelch is disabled) and channel de-activation through
TWS interface. Status and alarm information are available
via the TWS interface. The interrupt signal (selectable via
the TWS interface as a pulse or static level) is provided to
inform hosts of an assertion of an alarm and/or LOS.
Transmitter Input Equalization
Transmitter inputs can be programmed for one of several
levels of equalization. See Figure 4. The default case
provides a flat gain-frequency response in the inputs.
Different levels of compensation can be selected to
equalize skin-effect losses across the host circuit board.
See Tx Memory Map 01h Upper Page section addresses
228 - 233 for programming details.

Figure 3 shows the interface between an ASIC/SerDes and
the fiber optics modules. For simplicity, only one channel
is shown. As shown in the Figure 3, the compliance
points are on the host board side of the electrical connectors. Sets of s-parameters are defined for the transmitter and receiver interfaces. The transmitter and receiver
are designed, when operating within Recommended
Operating Conditions, to provide a robust eye-opening at
the receiver outputs. See the Recommended Operating
Conditions and the Receiver Electrical Characteristics for
details.

The transmitter inputs support a wide common mode
range and DC blocking capacitors may not be needed –
none are shown in Figure 3. Depending on the common
mode range tolerance of the ASIC/SerDes inputs, DC
blocking capacitors may be required in series with the
receiver. Differential impedances are nominally 100 Ω.
The common mode output impedance for the receiver is
nominally 25 Ω while the nominal common mode input

Receiver Output Amplitude and De-emphasis
Package Outline
Receiver outputs can be programmed to provide several
levels of amplitude and de-emphasis. See Figure 5 for deemphasis definition. The user can program for peak-topeak amplitude and then a de-emphasis level. If zero deemphasis is selected, then the signal steady state equals
the peak-to-peak level. For other levels of de-emphasis
the selected de-emphasis reduces the steady-state from
the peak-to-peak level. The change from peak-to-peak
level to steady-state occurs within a bit time. See Rx
Memory Map 01h Upper Page section addresses 228 - 233
for amplitude programming details and addresses 234 –
239 for de-emphasis programming details.
The module is designed to meet the package outline
defined in the PPOD MSA. This MSA follows the outline
of the SNAP12 MSA except for the position of the MEGArray® connector and pin assignments. See the package
outline and host board footprint figures (Figures 23 -26)
for details.
Control Signal Interface
The control interface includes dedicated signals for
address inputs, interrupt output and reset input and bidirectional clock and data lines for a two-wire serial access
(TWS interface) to control and status and information
registers. The TWS interface is compatible with industry
standard two-wire serial protocol scaled for 3.3 volt LVTTL.
It is implemented as a slave device. Signal and timing
characteristics are further defined in the Control Characteristics and Control Interface & Memory Map sections.
The registers of the serial interface memory are defined in
the Control Interface & Memory Map section.
Regulatory & Compliance Issues
Various standard and regulations apply to the modules.
These include eye-safety, EMC, ESD and RoHS. See
the Regulatory Section for details regarding these and
component recognition. Please note the transmitter module is a Class 1M laser product – DO NOT VIEW
RADIATION DIRECTLY WITH OPTICAL INSTRUMENTS. See
Regulatory Compliance Table for details.

Handling and Cleaning
The transmitter and receiver modules can be damaged
by exposure to current surges and over voltage events.
Care should be taken to restrict exposure to the conditions defined in the Absolute Maximum Ratings. Wave
soldering, reflow soldering and/or aqueous wash process
with the modules on board are not recommended.
Normal handling precautions for electrostatic discharge
sensitive devices should be observed.
Each module is supplied with an inserted port plug for
protection of the optical ports. This plug should always
be in place whenever a fiber cable is not inserted.
The optical connector includes recessed elements that
are exposed whenever a cable or port plug is not inserted.
Prior to insertion of a fiber optic cable, it is recommended
that the cable end be cleaned to avoid contamination
from the cable plug. The port plug ensures the optics
remain clean and no addition cleaning should be needed.
In the event of contamination, dry nitrogen or clean dry
air at less than 20 psi can be used to dislodge the contamination. The optical port features (e.g. guide pins) preclude
use of a solid instrument. Liquids are also not advised.

Link Model and Reference Channel
Performance specifications for the AFBR-775BxxxZ
Transmitter and AFBR-785BxxxZ Receiver are based on
a reference channel model. A reference channel model
provides the basis for inter-operability between independently produced transmitter and receiver modules. The
reference model used for the AFBR-775BxxxZ Transmitter and AFBR-785BxxxZ Receiver is based on the industry
standard 10GbE link model (10GEPBud3_1_16a.xls
available at the IEEE P802.3ae 10Gb/s Ethernet Task Force
Serial PMD Documents website http://www.ieee802.
org/3/ae/public/adhoc/serial_pmd/documents/ ).
As shown in Figure 6, a channel for a fiber optic link
comprises a transmitter, receiver and cable plant with
inputs at test point TP1 and outputs at test point TP4.
The test points TP1 and TP4 coincide with the compliance
points defined in Figure 3. The cable plant here includes
the fiber and two inline connectors.
A reference channel permits the effect of various channel
attributes to be referred to different points in the channel
and accumulated. For example, in the GbE (All_1250.
xls available at the IEEE website http://grouper.ieee.org/
groups/802/3/10G_study/public/email_attach/All_1250.
xls ) and 10 GbE models all signal impairments are
captured and translated into power penalties. Also, the
effect of transmitter and fiber attributes are also captured
and referred to TP3 to define stressed receiver test criteria.
Similarly, all effects upstream of TP4 can be captured and
referred to TP4 and combined at this point into a figure of
merit. Since the signal at TP4 is electrical and not optical
there are advantages for this.
To ensure inter-operability among independently
produced transmitters and receivers, definition of acceptable devices is required. This can be accomplished on
an individual parameter basis by setting min/max limits
or with aggregates of attributes by establishing a figure
of merit. Referring again to the 10GbE link model, the
entity ‘margin at target distance’ is an aggregate figure of
merit of all link attributes. There a set of link attributes
will yield a specific link margin and a worst case set of link
attributes can be defined for a minimum level of performance. Instead of placing a maximum or minimum limit
on each attribute, it is possible to allow elements in the
set to shift (i.e. tradeoff with others within the set) as long
as the desired margin is achieved. Further, if ‘margin at
target distance’ can be translated into eye opening at
TP4, the aggregate figure of merit is directly measurable. To preserve independence for transmitter, receiver
and fibers, it is required that transmitter attributes only
trade-off with other transmitter attributes and, similarly,
receiver attributes can only trade-off with other receiver
attributes.
In this data sheet, a minimum eye width at TP4 for a
specified maximum BER is the figure of merit used to
define acceptable link performance. Additional inputs
and calculations have been added to the 10GbE link
model to calculate eye closure and the effects of all impairments are referred to TP4 and combined as elements
of eye closure. The minimum eye width at TP4 is included
in tables, Transmitter Optical Characteristics and Receiver
Electrical Characteristics, as minimum “Reference Link
Output Eye Width’.
Note:
1. The Recommended Operating Conditions table and those for
transmitter and receiver characteristics provide the necessary
attributes to define the worst case set for the reference channel.
Various elements of this worst case set are labeled ‘Informative’ and
are allowed to range outside the maximum or minimum limit for the
individual element when there is a compensating improvement in
others of the worst case subset. Transmitter attribute tradeoffs are
limited to the transmitter subset and receiver tradeoffs are limited to
the receiver subset.
The following two tables summarizes the practical tradeoffs between different informative transmitter parameters, as well as different informative receiver parameters,
respectively. Although the wavelength and spectral width
can also trade off with each other, they are not included
here for interoperability reason.

The reference model for testing transmitters consists
of a pattern generator, fiber optic test cable, attenuator,
test receiver and BERT. See Figure 7 for the evolution of
a reference channel to a transmitter test channel. Differences between the worst case values for attributes in
the reference model and those in the test equipment set
can be compensated by an added attenuator (note that
the 10GbE model translates all impairments into power
penalties) and adjustments in TJ criteria at TP4. Differences in the TP1 input jitter between the defined conditions, TJ r and DJ r, for the reference channel and actually
provided in the test channel, TJ t and DJ t, can also be
accommodated by adjustments to TP4 test criteria (TJ r
becomes TJ t). The extended 10GbE Link model is used to
determine the compensating attenuation and TP4 criteria
adjustments.
The reference for testing receivers consists of a pattern
generator, test transmitter, fiber optic test cable, attenuator and BERT. See Figure 8 for the evolution of a reference
channel to a receiver test channel. In a similar manner
as with the transmitter, all differences between the test
equipment and worst case channel are compensated with
an attenuator and adjustments in the TP4 criteria.

Absolute Maximum Ratings
Stress in excess of any of the individual Absolute Maximum Ratings can cause immediate catastrophic damage to the
module even if all other parameters are within Recommended Operation Conditions. It should not be assumed that
limiting values of more than one parameter can be applied to the module concurrently. Exposure to any of the Absolute
Maximum Ratings for extended periods can adversely affect reliability.

Notes:
* Control signals, LVTTL (3.3 V) compatible, include Adr[2:0], IntL, ResetL, SCL and SDA.
1 The position for case temperature measurement is shown in Figure 11. Continuous operation at the maximum Recommended Operating Case
Temperature should be avoided in order not to degrade reliability. Modules will function (degraded performance may result) where operated with
case temperatures below the minimum Recommended Operating Case Temperature.
2. While operation for various codes, e.g. 8b10b, are supported, certain parameters, jitter and sensitivity, are defined for specific operating conditions
of 5.0 GBd and 8b10b equivalent test patterns. The receiver has a low frequency -3dB corner near 100 kHz.
3. Data inputs are CML compatible. Minimum input requirement holds for default input equalization settings. Data Input Differential Peak to Peak
Voltage Swing is defined as follows: ΔVDI pp = ΔVDIH – ΔVDIL where ΔVDIH = High State Differential Data Input Voltage and ΔVDIL = Low State
Differential Data Input Voltage.
4. Data Input Common Mode Voltage is defined as follows: VDICM = (VDinp + VDinn)/2.
5. Deterministic Jitter, DJ, conforms to the dual-Dirac model where TJ(BER) = DJ + 2Q(BER)RJrms and RJrms is the width of the Gaussian component.
Here BER = 10-12. DJ is measured with the same conditions as TJ. Effects of impairments in the test signal due to the test system are removed from
the measurement. All channels not under test are operating with similar test patterns.
6. Total Jitter, TJ, defined for a BER of 10-12, is measured at the 50% signal level using a 5.0 GBd Pseudo Random Bit Sequence of length 27-1 (PRBS7),
or equivalent, test pattern. Effects of impairments in the test signals due to the test system are removed from the measurement. All channels not
under test are operating with similar test patterns.
7. Power Supply Noise is defined as the peak-to-peak noise amplitude over the frequency range at the host supply side of the recommended power
supply filter with the module and recommended filter in place. Voltage levels including peak-to-peak noise are limited to the recommended
operating range of the associated power supply. See Figures 12 and 13 for recommended power supply filters.
8. For data pattern with restricted run lengths and disparity, e.g. 8b10b, smaller value capacitors may provide acceptable results.
9. Channel insertion loss includes 3.5 dB/km attenuation, 1.5 dB connector loss and 0.3 dB modal noise penalty allocations.

1. Max conditions includes default output amplitude and de-emphasis programming.
2. Supply current includes that of all Vcc25 contacts. Max conditions include maximum output amplitude and de-emphasis programming.
3. Supply current includes that of all Vcc33 contacts. Max conditions include maximum output amplitude and de-emphasis programming.
4. Data outputs are CML compatible. Data Output Differential Peak to Peak Voltage Swing is defined as follows: ΔVDO pp = ΔVDOH - ΔVDOL
where ΔVDOH = High State Differential Data Output Voltage and ΔVDOL = Low State Differential Data Output Voltage. Impairments in
measurements due to the test system are removed.
5. Data Output Common Mode Voltage is defined as follows: VDO CM = (VDoutp + VDoutn)/2.
6. These are unfiltered rise and fall times without de-emphasis measured between the 20% and 80% levels using a 500 MHz square wave test
pattern. Impairments in measurements due to the test system are removed.
7. This is the module response time from fall of Rx input to less than Rx input LOS threshold to squelch of Rx outputs.
8. This is the module response time from rise of Rx input to greater than Rx input LOS threshold to resumption of Rx outputs.
9. Deterministic Jitter, DJ, conforms to the dual-Dirac model where TJ(BER) = DJ + 2Q(BER)RJrms and RJrms is the width of the Gaussian
component. Here BER = 10-12. DJ is measured with the same conditions as TJ. The receiver output is measured with default de-emphasis.
Effects of impairments in the test signals due to the test system are removed from the measurement. All channels not under test are operating
with test patterns at an input signal 6 dB above maximum Receiver Sensitivity.
10. Total Jitter, TJ, defined for BER of 10-12, is measured at the 50% signal level using a 5.0 GBd Pseudo Random Bit Sequence of length 27-1
(PRBS7), or equivalent, test pattern with characteristics that are equivalent to that of an AFBR 775B transmitter module and maximum cable
length operating per the Recommended Operation Conditions as the test source. Effects of impairments in the test signals due to the test
system are removed from the measurement. All channels not under test are operating with similar test patterns.
11. Eye Opening is defined as the unit interval less TJ for the same test pattern and conditions as TJ.
12. Measured over the range 100 MHz to 3.75 GHz with reference differential impedance of 100 Ω
13. Measured over the range 100 MHz to 3.75 GHz with reference common mode impedance 25 Ω
14. Measured over the range 100 MHz to 3.75 GHz with reference differential impedance 100 Ω
15. Power On Initialization Time is the time from when the supply voltages reach and remain within Recommended Operating Conditions to the
time when the module enables TWS access. The module at that point is fully functional.
16. Inter-Channel Skew is defined for the condition of equal amplitude, zero ps skew input signals.

Notes:
* Control signals include Adr[2:0], IntL, ResetL, SCL and SDA.
1. This is the module response time from a change in module address, Adr[2:0], to response to TWS communication using the new address.
2. This is the module response time from occurrence of interrupt generating event to IntL assertion, Vout:IntL = Vol.
3. Pulse or static level can be selected for IntL. Pulse mode is default. See Memory Map.
4. This is the module response time from clear on read operation, measured from falling SCL edge after stop bit of read transaction, until
Vout:IntL = Voh where IntL is in static mode.
5. Assertion of ResetL activates a complete module reset, i.e. module returns to factory default and non-volatile control settings. While ResetL
is Low, Tx and Rx outputs are disabled and the module does not respond to the TWS interface.
6. This is the response time from ResetL de-assertion to resumption of operation.
7. Data In Set Up Time is measured from Vil(max)SDA or Vih(min)SDA to Vil(max)SCL.
8. Data In Hold Time is measured from Vil(max)SCL to Vil(max)SDA or Vih(min)SDA.
9. Clock Low to Data Out Time is measured from Vil(max)SCL to Vol(max)SDA or Voh(min)SDA.
10 . Data Out Hold Time is measured from Vil(max)SCL to Vol(max)SDA or Voh(min)SDA.

Control Interface & Memory Map
The control interface combines dedicated signal lines for
address inputs, Adr[2:0], interrupt output, IntL, and reset
input, ResetL, with two-wire serial, TWS, interface clock,
SCL, and data, SDA, signals to provide users rich functionality over an efficient and easily used interface. The
TWS interface is implemented as a slave device and compatible with industry standard two-wire serial protocol.
It is scaled for 3.3 volt LVTTL. Outputs are high-z in the
high state to support busing of these signals. Signal and
timing characteristics are further defined in the Control
I/O Characteristics section. In general, TWS bus timing
and protocols follow the implementation popularized in
Atmel Two-wire Serial EEPROMs. For additional details
see, e.g., Atmel AT24C01A.
The address signals, Adr2, Adr1 and Adr0, provide the
ability to program the TWS bus address of the module.
The module address has the binary form 0101hjkx, where
h, j and k correspond to Adr2, Adr1 and Adr0, respectively and x corresponds to the Read/Write command bit.
Modules will respond to TWS bus addresses in the range
of 50h to 5Fh (hereafter 5ih) depending upon the state of
Adr2, Adr1 and Adr0. The address B0(h) should be avoided
on the TWS bus where these modules are used.
An interrupt signal, IntL, is used to alert the host of a loss
of input signal (LOS), transmitter fault conditions and/or
assertion of any monitor flag. This reduces the need for
dedicated status signal lines and polling the status and
monitor registers while maintaining timely alerts to significant events. IntL can be programmed (page 01h byte
225 bit 0) to either pulse or static mode with pulse as the
default mode.
A dedicated module reset signal, ResetL, is provided in
case the TWS interface becomes dysfunctional. When
ResetL is asserted, the outputs are disabled, TWS interface
commands are inhibited and the module returns to
factory default settings except Non-volatile Read-Write
(RWn) registers which retain the last write. A module
register (memory map except the non-volatile registers)
reset can also be initiated over the TWS interface (page
5ih byte 91, bit 0). A TWS reset can be initiated by nine
SLA clock cycles with SDA high in each cycle and creating
a start condition.
With the TWS interface the user can read a status register
(page 5ih byte 2) to see if data is available in the monitor
registers, if the module has generated an IntL that has not
been cleared and global status reports for loss of signal
and fault conditions.
LOS, Tx fault and/or monitor flag registers can be accessed
to check the status of individual channels or which channel
may have generated a recent IntL. LOS, Tx fault and flag
bits remain set (latched) after assertion even in the event
the condition changes and operation resumes until
24
cleared by the read operation of the associated registers
or reset by ResetL or the TWS module reset function.
The user can read the present value of the various monitors.
For transmitters and receivers, internal module temperature and supply voltages are reported. For transmitters,
monitors provide for each channel laser bias current and
laser light output power (LOP) information. For receivers,
input power (Pave) is monitored for each channel. In
addition, elapsed operating time is reported. All monitor
items are two-byte fields and to maintain coherency,
the host must access these with single two-byte read
sequences. For each monitored item, alarm thresholds
are established. If an item moves past a threshold, a flag is
set, and, provided the item is not masked, IntL is asserted.
The threshold settings are available in the upper memory
page, 01h.
The user can select either a pulse or static mode for the
interrupt signal IntL and initiate a module register reset.
The user is provided the ability to disable individual
channels. For transmitters, equalization levels can be
independently set for individual channels. For receivers,
output signal amplitude, de-emphasis levels and rate
select can be independently set for individual channels.
In the upper page, 01h, control field the user can invert
the truth of the differential inputs for individual transmitter channel and for the differential outputs of individual
receiver channels. In addition, the user can disable the
output squelch function on an individual channel basis
for both transmitters and receivers. For transmitters
the user can, on an individual channel basis, activate a
margin mode that reduces the output optical modulation
amplitude for the channel.
All non-volatile control registers are located in the upper
page 01(h). Non-volatile functions include the IntL mode
selection bit, input and output polarity flip bits, transmitter equalization control bits, receiver output amplitude
control and receiver output de-emphasis control. Entries
into these registers will retain the last write for supply
voltage cycles and for ResetL and module register resets.
Volatile functions include module register reset, channel
disable, squelch disable and margin activation.
A mask bit that can be set to prevent assertion of IntL
for the individual item exists for every LOS, Tx fault and
monitor flag. Mask fields for LOS, Tx fault and module
monitors are in the lower memory page, 5ih, and the mask
field for the channel monitors are in the upper page 01h.
Entries in the mask fields are volatile.
Page 00h, based on the Serial ID pages of XFP and QSFP,
provides module identity and information regarding the
capabilities of the module.
Memory Map Overview
The memory is structured as a single address, multiple
page approach after that in the XFP MSA and adapted
by QSFP MSA for multi-channel transceivers. Figure 27

Transmitter Input Equalization Control Code Description
Control registers 228 through 233 permit input equalization control. Four bit code blocks (either bits 7 through 4 or 3
through 0 where bit 7 or 3 is the msb) are assigned to each channel.
Codes 1xxx are reserved.
Code 0111 calls for full scale equalization and code 0000 calls for no equalization.
Intermediate code values provide intermediate levels of compensation.
