EDFA and DWDM Testing
Simple EDFA Test
The ASE interpolation method is used to measure gain, NF, and key parameters for optical fiber amplifier evaluation. With the WDM-NF 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.

Automated EDFA Test
In conjunction with Grid TLS, 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.

WDM OSNR Test
AQ6370D'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.
