Operational Overview
The ASE-1019 is an ASE light source providing a typical output power of +19 dBm. It is one of the
series of amplifier/light source modules which are designed as user-friendly, compact, portable,
cost-effective solutions for use in a variety of applications.
A detailed block diagram showing the
internal hardware connectivity of this chassis is shown in Figure 2.0-1.
An Ethernet communications hardware interface is provided to allow the ASE-1019 to be
controlled via a 10/100BaseT link using either Static or Dynamic IP addressing. In this
configuration, a standard HTML browser (e.g. Firefox, Chrome, Internet Explorer) provides the user
interface and the various control and status HTML pages are integrated into the microcontroller’s
firmware. A +5V AC/DC adapter is provided to power the module.
In addition to the Ethernet GUI, the ASE-1019 can be connected directly to a Windows based
computer which runs the USB graphical user interface (GUI) software. This GUI also provides
complete control and status of all amplifier and optical power monitoring functions.
The output optical power level is measured using a 1% tap to minimize insertion loss. An onboard
temperature sensor allows the power monitoring circuitry to be calibrated during production test
to provide measurement resolution of 0.01 dB and linearity (relative accuracy) of 0.1 dB over an
operating temperature range of 0°C to 40°C.

The GUI application has an additional optional feature which allows the user to perform time
stamped data logging. This option includes capturing the input and output optical power levels as
