AQ6370-APPLICATIONS
SIMPLE EDFA TEST
The
ASE interpolation method is used to measure gain, NF, and key
parameters for optical fiber amplifier evaluation. With WDMNF analysis
function, up to 1024 channels of multiplexed signals can simultaneously
be tested. An ASE level for NF measurements is calculated by using a
curve-fit function for each WDM channel. The curve-fit and source
spontaneous emission (SSE) suppress function enhance a measurement
accuracy.
Automated EDFA Test
In conjunction with DFB-LDs, optical attenuator and optical switches,
an EDFA auto test system can easily be established. This system does
not require manual reconfiguration of optical paths and adjustments of
EDFA input power, and that improves measurement throughput and avoids a
human error. AQ2200 series is a modular system suitable for building
such a system. 
Example of automated EDFA test configuration
Transceiver/LD Test
In
conjunction with bit error rate test (BERT) equipment, the AQ6370 can
measure the center wavelength and spectral width of transceivers and LD
modules. Various built-in analysis functions, such as DFB-LD, FP-LD
(VCSEL), and LED facilitate test process.
WDM OSNR Test
AQ6370's wide close-in dynamic range allows accurate OSNR measurement of DWDM transmission systems (up to 50 GHz spacing). The built-in WDM analysis function analyzes the measured waveform and shows peak wavelength, peak level and OSNR of WDM signals up to 1024 channels simultaneously. The curve fit function is used to accurately measure noise levels.Passive Component Test
In
conjunction with a white light source, an ASE light source or other
broadband light source, you can simply perform evaluation of passive
devices such as WDM filters and FBG. The AQ6370's superb optical
characteristics enable higher-resolution and wider dynamic range
measurements.
The built-in optical filter analysis function simultaneously reports peak/bottom wavelength, level, crosstalk, and ripple width.
