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

µm core PMF

panda-type fiber. (914

µm) diameter, tight-buffered

outer jacket. The standard length is 39 in. ± 4 in.

(1 m ± 10 cm) and is terminated with an

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

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.
