Operational Overview
The AMP-1030P is an optical pre-amplifier providing a minimum gain of +30 dB with a -30 dBm
input signal. It is one of the AMP-1000 series of amplifier 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.
The AMP-1030P can be USB powered and connects directly to a Windows based computer which
runs the USB graphical user interface (GUI) software. The GUI provides complete control and status
of all amplifier and optical power monitoring functions.
In addition to the USB GUI, an Ethernet communications hardware interface is provided to allow
the AMP-1030P 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.
The input and output optical power levels are measured using a 1% tap to minimize insertion loss.
An isolator is used prior to the optical amplifier in order to minimize backward ASE noise. 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
well as the corresponding amplifier bias current, operating modes, temperature, LOS level and
alarms, and writing this information to a .csv file.
