Optical Amplifier Analyzer
AQ8423Z

Dual Band Optical Amplifier Analyzer
Switchable C-band and L-band


Dual Band Optical Amplifier Analyzer
Switchable C-band and L-band

The AQ8423Z is a unique dual-range optical amplifier
analyzer. In conjunction with an external optical
spectrum analyzer (OSA) and light sources (such as
tunable laser sources or DFBs), the AQ8423Z can
measure gain and noise figure (NF) of optical amplifiers
both in C-band and L-band. Two testing wavelength
ranges can be switched internally by simple
operation.

The AQ8423Z employs the proven "Pulse
method" technique. It utilizes 1 MHz modulation frequency,
which is high enough to suppress a rise of
ASE (amplified spontaneous emission) level during
off signal. The AQ8423Z can achieve very high
accuracy in ASE measurement resulting in accurate
NF measurement.

Since the AQ8423Z can eliminate all DWDM signals
simultaneously during ASE measurement, it
can obtain measurement results under actual
DWDM operational conditions.

Features

 Pulse method with 1 MHz modulation
High enough frequency to suppress a rise of ASE
during a measurement

 C- and L-band measurement capability
Measurement range is switchable, either to
C-band (1520-1580 nm) or L-band (1560-1620 nm)

 DWDM measurement mode
A DWDM amplifier, with multi-tone signals, can be
measured under its actual operational conditions.

 Hands-free calibration
New hands-free calibration function, added to full
user calibration feature, makes daily calibration simple
and quick.

 Maximum test channel: 200 channels
 Minimum channel spacing: 25 GHz

Notes

. Optical spectrum analyzer has to be ANDO product (AQ6317B is recommended).
. Optical spectrum analyzer is fully controlled by AQ8423Z via GP-IB during a measurement.
. A bunch of DFB-LDs and tunable laser source can be used as an external light source. Tunable laser source from different
manufacturers can be controlled via GP-IB by AQ8423Z.

WDM Signals + ASE ASE
The AQ8423Z modulates signals from external
light sources with AOM1, and AOM2 selects
the timing to measure, signal or ASE (Amplified
spontaneous emission).

When AOM2 is set for ASE measurement,
AOM2 eliminates the source signal and SSE
(Source spontaneous emission) without affecting
the ASE level (to increase input power, a
booster amplifier can be added to external
light sources, the SSE includes ASE of the
booster amplifier in this case). Thus, the
AQ8423Z can measure the ASE at a signal
wavelength very accurately.

The modulation frequency is also very
important. It strongly affects ASE measurement
accuracy, which results in an error on NF.
In order to minimize ASE measurement errors,
the AQ8423Z modulates a source signal with
1 MHz, which is high enough to suppress a
rise of ASE level, to obtain high accuracy.
