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.

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.
