Module Processing
The module can withstand normal wave soldering pro-
cesses. 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.
Connector Options
The standard fiber-optic pigtail is an 8
μ
m core PMF
panda-type fiber. (914
μ
m) diameter, tight-buffered
outer jacket. The standard length is 39 in. ± 4 in.
(1 m ± 10 cm) and is terminated with an ST
optical
connector.
Installation Considerations
Although the module has been designed with rugged-
ness 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).
Pin Information
1. Laser back-facet and bias alarm functions are customer-use
options that are not required for normal operations of the transmit-
ter
and are normally used during manufacture and for diagnostics.
The output will optionally be either a logic signal or an analog volt-
age. All alarm, select, and enable signals are active-high.
2. NUC = no user connection.
