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.
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
In conjunction with bit error rate test (BERT) equipment,
the AQ6370B 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.
