Description
The T92-Type 10 Gb/s laser transmitters are
designed for use in transmission systems and high-
speed data communication applications. For trans-
mission system applications, the transmitter oper-
ates at the SONET OC-192 standard and FEC rates,
and SDH rate of STM-64 standard and FEC rates as
per ITU-T G.709. For high-speed data communica-
tions, the transmitter operates at 10G Ethernet rate
and 10G Fibre Channel rate.
The transmitters meet all present Telcordia Technol-
ogies
TM GR-253-CORE requirements and the ITU-T
G.693 recommendations. The transmitters are also
ideally suited for extended distance data and net-
working applications.
Manufactured in a 24-pin DIP assembly, the trans-
mitter uses an hermetic, isolated, 1300 nm MQW
DFB laser, an InGaAs PIN photodiode back-facet
monitor and a GaAs laser driver IC. The transmitter
requires a single power supply (5.2 V or +5.0 V).
Pin information is listed in Table 1.

Description
(continued)
Transmitter Processing
The transmitter can withstand normal wave soldering
processes. The complete transmitter module is not her-
metically sealed; therefore, it should not be immersed
in or sprayed with any cleaning solution or solvents.
The process cap and fiber pigtail jacket can deform at
temperatures greater than 85 C. The transmitter pins
can be wave-soldered at a maximum temperature of
250 C for 10 seconds.
Installation Considerations
Although the transmitter has been designed with rug-
gedness in mind, care should be used during handling.
The optical connector should be kept free from dust,
and the process cap should be kept in place as a dust
cover when the device is not connected to a cable. If
contamination is present on the optical connector, the
use of canned air with an extension tube should
remove any debris. Other cleaning procedures are
identified in the Cleaning Fiber-Optic Assemblies Tech-
nical Note (TN95-010).
Laser Degrade-Mode Alarm
An output of the transmitter that indicates when the
laser bias has reached its end-of-life condition. The
transmitter will still function, but may not meet all speci-
fications. The transmitter should be replaced when this
alarm is active (active-low). Specifically, this alarm indi-
cates that the bias of the laser has changed more than
50% from its original value.
Back-facet Monitor Output
This is an analog output that indicates whether the
transmitter has the correct optically generated back-
facet current. It may be used for alarm purposes. It is
referenced to V
EE
. Under normal operating conditions,
this monitor will output a voltage that is nominally
500 mV above V
EE
. When the optical output power of
the transmitter increases or decreases, this voltage will
move proportionately.
Bias Monitor Output
This is an analog output voltage that indicates the bias
current being supplied to the laser. It is referenced to
V
EE
. The conversion for this monitor output is 20 mV
for every 1 mA of bias current to the laser. For exam-
ple, a 400 mV output above V
EE
would indicate 20 mA
of bias current to the laser.
Table 1. Pin Descriptions
1. Laser back-facet function is a customer-use option that is not
required for normal operations of the transmitter and is normally
used during manufacture and for diagnostics.
2. Laser temperature (C) = (V
TEMP
0.5 V)/0.01 V, where V
TEMP
is
the temperature monitor voltage.
3. This pin can be tied to ground.
4. For single-ended operation, data signal must be on pin 16, and
DATA
(pin 18) must 50
terminated to ground.
NUC = No user connection. Pin must not be tied to ground or any
other circuit potential.

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are abso-
lute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess
of those given in the operations sections of the data sheet. Exposure to absolute maximum ratings for extended
periods can adversely affect device reliability.
Characteristics
(Minimum and maximum values specified over operating case temperature range at 50% duty cycle data signal.
Typical values are measured at room temperature unless otherwise noted.)
1. With V
EE
connected to 5.2 V, V
CC
must be at 0 V; With V
CC
connected to +5.0 V, V
EE
must be at 0 V.
2. Inputs are ac-coupled into an equivalent input impedance of 50
.
3. Single-ended or differential operation may be used. If the inputs are driven single-ended, Data must be 50
terminated to ground.
4. The transmitter is normally enabled and requires an external voltage to disable.
5. This alarm will go active when the bias current to the laser has increased 50% or more from its beginning-of-life (BOL) value.
6. This voltage is measured from Pin 3 to V
EE
and is converted to laser bias current with the ratio of 20 mV/mA.
7. This voltage is measured from Pin 2 to V
EE
.

Qualification and Reliability
To help ensure high product reliability and customer satisfaction, TriQuint is committed to an intensive quality pro-
gram that starts in the design phase and proceeds through the manufacturing process. Optoelectronics modules
are qualified to TriQuint's internal standards using MIL-STD-883 test methods and procedures and using sampling
techniques consistent with Telcordia Technologies requirements. This qualification program fully meets the intent of
Telcordia GR-468-CORE reliability practices. In addition, the TriQuint design, development, and manufacturing
facility has been certified to be in full compliance with ISO
9001 Quality System Standards.
Electrostatic Discharge
CAUTION: This device is susceptible to damage as a result of electrostatic discharge. Take proper precau-
tions during both handling and testing. Follow guidelines such as JEDEC Publication No. 108-A
(Dec. 1988).
TriQuint employs a human-body model (HBM) for ESD-susceptibility testing and protection-design evaluation. ESD
voltage thresholds are dependent on the critical parameters used to define the model. A standard HBM (resistance
= 1.5 k
, capacitance = 100 pF) is widely used and can be used for comparison purposes. The HBM ESD with-
stand voltage established for the T923-type transmitter is 100 V.
