YOKOGAWA AQ6370E Telecom Optical Spectrum Analyzer 600-1700nm

The Yokogawa AQ6370E’s overall high performance can cover not only manufacturing of optical devices and optical transmission systems but also research and development, and a variety of other applications.

• • Optical active devices

Laser diode/Fiber laser/Optical amplifier/Optical transceiver

• • Optical passive devices

Filter/FBG/AWG/WSS/ROADM/Optical fiber

• Optical transmission equipment (DWDM, CWDM)
• Development support of Applied photonics equipment

OSNR Measurement on DWDM System

The Yokogawa AQ6370E’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.

Optical Amplifier (EDFA) Measurement

The ASE interpolation method is used to measure gain, NF, and key parameters for optical fiber amplifier evaluation. With 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.

Data Logging Function

The Data Logging function records analysis results such as WDM analysis (OSNR, optical signal/noise ratio), distributed feedback laser diode (DFB-LD) analysis, and multi-peak measurements at up to 10,000 points per channel with time stamps. Recorded data can be displayed in table and graphical forms. This function is useful for the long-term stability testing and temperature cycle testing of systems and devices. The optical spectrum of each measurement can also be stored for reviewing and troubleshooting.

Example of the data logging display

Advanced marker function

The Advanced Marker function adds markers to obtain the power density and the integrated power of a designated spectrum. This new feature makes it easy to get an OSNR value of the signal, whether modulated or not, directly from its spectrum.

Example of the advanced marker

Gate sampling function

The Gate Sampling function facilitates the recirculating loop testing of optical transmission systems. Using an external gate signal, the Yokogawa AQ6370E obtains the optical spectrum of the signal which is passing through a certain loop. The advantage of this approach is its speed compared with the conventional External Trigger or Sweep Enable function.

Resolution calibration function

The Resolution Calibration function is used to calibrate the noise equivalent bandwidth with an external light source. With this new feature, the measurements of power density of a broad spectrum light source will be more accurate
