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 (TN95-010LWP).
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 optional analog output voltage that indicates
the bias current being supplied to the laser. It is refer-
enced to V
EE
. The conversion for this monitor output is
20 mV for every 1 mA of bias current to the laser. For
example, 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; for single-ended
clocked operation, clock signal must be on pin 20, and
CLOCK
(pin
22) must be 50
terminated to ground.
