Figure 4.2-1 - ASE-1019 Laser Radiation Safety Label for Class 1M Laser Product
ASE-1019 Safety Specifications:
1) Wavelength range: 1520 to 1620nm (invisible, infrared region).
2) Beam size: The beam is normally safely confined within a single-mode optical fiber with a
mode-field diameter of about 10-um.
3) Beam divergence: If the beam is allowed to escape into free space (e.g. by not connecting an
optical cable to the input or output connectors, with the dust caps removed), the beam
divergence is given by the numerical aperture of the optical fiber, typically 120mrad (half
angle).
4) Maximum power: The maximum output power (in the form of amplified spontaneous
emission (ASE)) of this module, in the absence of an optical input, is less than the Class 1M
limit of 135 mW (21.3 dBm). This power can be emitted from the output connector (ASE
power emitted from the input connector does not exceed Class 1 limits.). With a saturating
input signal of 0 dBm (1mW), the maximum output power of the module is also less than
135 mw (21.3 dBm).
4.3
Connecting Optical Cables
Optical connections to the module are made via FC connectors. The supplied dust caps should
always be left on the connectors when not in use. These dust caps not only keep the connectors
clean, but they also protect the user from any optical radiation that may emanate from these
connectors.
4.4
Eye Protection
Under normal operating conditions, with an optical cable connected to the output, or with the
dust caps on both FC connectors, there is no optical radiation emitted into free space. Therefore,
no special eye protection is required. It is recommended that optical connection or disconnection
to the module be carried out only with the optical output disabled using the GUI.

USB GUI Software Installation and Initial Power-On
This paragraph describes the USB GUI installation and power-on procedure so if only the Ethernet
interface is planned to be used, please skip to paragraph 6.0.
5.1
USB GUI Installation
Before initially powering on the ASE-1019 module, the USB GUI should be installed onto a
Windows 7, XP, or 8 computer. The included CD-ROM contains all of the required installation files.
Proceed to install the USB GUI by following the instructions in Table 5.1-1. Several screen captures
of the installation process are shown in the figures below.
The installation procedure will install the ASE-1019 GUI application program as well as the National
Instruments Run Time Engine and all USB drivers needed to communicate with the ASE-1019
module. Therefore, no additional driver or software installation is necessary.
