The AQ6380 achieves a wavelength resolution of 5 pm. It enables to separate closely allocated DWDM channels and modulation side peaks of optical transceivers.
The monochromator has sharper spectral characteristics than ever. Signals in close proximity (e.g., residual longitudinal modes of external cavity laser) can be clearly separated and accurately measured.
The AQ6380 has a wavelength band of 1200 to 1650 nm. This means a single unit can meet diversifying wavelength measurement needs. Wavelength resolution can be varied from 5 pm to 2 nm, supporting a wide range of applications from narrowband peak/notch measurements to wideband spectral measurements. In addition, the increased resolution contributes to an improvement in measurement speed and accuracy for low power signals.
Stray light is optical noise caused by the diffuse reflection of incident light inside a monochromator. In situations such as laser SMSR measurement, where multiple optical spectra with different levels are measured at the same time, the stray light can interfere with the measurement. When this occurs, high stray light suppression performance is required. The AQ6380 provides high dynamic range measurements with excellent stray light suppression performance of 80 dB, with no spurious noise generated.
In the near-infrared wavelength range there are wavelength regions where strong light absorption is observed due to the influence of water vapor in the air. In an OSA, there is a wavelength band in which the light absorption characteristics of water vapor inside the monochromator are noticeably detected. Such phenomena interferes with accurate optical spectrum measurements in the applicable wavelength band. The AQ6380 is equipped with a purge mechanism that replaces the air inside the monochromator with nitrogen or dry air by continuously supplying it through dedicated ports on the back panel. This results in accurate measurements that are unaffected by the light absorption phenomenon of water vapor.
The AQ6380 offers ±5 pm in the C band to meet the most stringent accuracy requirements. It also offers ±10 pm in the S and L bands and ±50 pm over the entire wavelength range. With such accuracy, some applications may not require an optical wavelength meter anymore. Periodic self-wavelength calibration using the built-in wavelength reference light source ensures long-term stability for each measurement.
Ambient temperature change, vibrations, and shock affect the measurement accuracy of high precision products such as optical spectrum analyzers. The AQ6380 delivers high-precision measurements long-term with the wavelength calibration and alignment adjustment functions using the built-in light source. Wavelength calibration with the internal light source can be performed fully automatically and regularly without an external fiber cord. Wavelength calibration using an external light source is supported and is accomplished by setting the exact wavelength.
The optical input uses a PC-type single-mode fiber. It achieves an optical return loss of 30 dB or more (even when connected with a PC-type optical plug) and reduces the impact of reflectioni-sensitive optical devices on measurements.
With a new sensitivity mode (RAPID) specialized for CW light, measurement speed is up to 20x faster than conventional models.
Sensitivity settings have a significant impact on measurement time. The AQ6380 has two modes and 19 sensitivity settings. Shorten measurement time by selecting the optimum sensitivity according to the type of optical signal and the minimum sensitivity requirement. Measurement sensitivity can also be set numerically. The appropriate sensitivity setting is automatically selected when entering the required minimum sensitivity value.
The AQ6380 has built-in analysis functions to characterize optical spectrum from a variety of optical systems and devices including WDM, DFB-LD, EDFA, and filters. The automatic calculation of the major parameters of the device under test will contributes to fast characterization. Analysis functions include DFB-LD, FP-LD, LED, spectral width (peak/notch), SMSR, optical power, WDM (OSNR), EDFA (NF and gain), filter (peak/bottom), and WDM filter (peak/bottom).
The appplication mode (APP) transforms an OSA into a versatile machine dedicated to a device under test (DUT). APP mode provides a DUT-specific user interface that navigates the user from configuration settings to test result output without worrying with other OSA settings. The AQ6380 comes pre-installed with several standard applications including WDM testing, DFB-LD testing, and FP-LD testing. Additional optional applications are available for download from the Yokogawa Test&Measurement website.
Easily build an automated measurement system using a remote-control interface (Ethernet or GP-IB). The remote command set conforms to the Standard Commands for Programmable Instruments (SCPI), compatible with AQ6370 series and AQ6319, as well as proprietary AQ6317-compatible commands, allowing for easy upgrades to existing measurement systems.
Emulate and remotely control the AQ6380 using OSA Viewer, the application software included with the AQ6370 Viewer. OSA Viewer's user interface and analysis capabilities allow R&D and production users to easily view and analyze waveforms on their PC or laptop. The AQ6380 can be controlled remotely via a direct connection or over a network. The screen image from the AQ6380 displays in real time on remotely-connected PCs or laptops, where you can operate it as if you are using the AQ6380 directly, and data files saved on the AQ6380 are remotely transferable to your computer. These features are ideal when R&D users need to evaluate and analyze measurement data and optimize test conditions and troubleshoot on remote lines, as well as when Production users need to collect and analyze measurement results of remote production lines.
With over four decades perfecting the user experience, the Precision Makers of Yokogawa Test&Measurement developed the AQ6380 with an easy-to-use front-panel design and intuitive operability.
The high-resolution, responsive 10.4-inch multi-touch capacitive touchscreen makes device operation simple and intuitive. Easily change the view and measurement conditions and perform analysis with just a touch. In the optical spectrum view, the waveform view can be zoomed or shifted by a simple tap and drag.
Operability is improved with the addition of frequently-used function keys on the front panel. These include sweep control (Auto/Single/Repeat/Stop), resolution, and sensitivity. The function keys can also be displayed as a pop-up on the screen.
To test a multi-channel, narrowly-spaced WDM system, high-spectral measurement performance is required to test the system’s internal circuit boards (e.g., laser modules, optical transceivers, final output signal). This includes simultaneous peak and OSNR measurements. AQ6380’s wide close-in dynamic range allows accurate OSNR measurement of DWDM transmission systems. 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.
Testing of optical components used in WDM transmission systems such as laser devices, laser modules, and optical transceivers requires high accuracy. Example applications include modulated signal measurement of optical transceivers and transponders and measurement of all channels of optical transceivers with WDM technology beyond 100 G. The AQ6380’s sharp spectral characteristics and high straylight suppression performance enables users to visualize and accurately measure spectral peaks in close proximity.
In conjunction with a broadband light sources such as ASE, SLD, or Super Continuum (SC), the AQ6380 enables higher resolution and wider dynamic range measurements and performs evaluation of passive devices including WDM, FBG, ROADM, and WSS. In addition, the built-in optical filter analysis function simultaneously reports peak/bottom wavelength, level, crosstalk, and ripple width.
The AQ6380 has USB ports that are compatible with a USB storage device, mouse, and keyboard. The file feature allows users to save data and screenshots to internal memory or USB storage for use in creating test reports. By connecting a mouse or keyboard to the USB port, you can comfortably operate the AQ6380 as if you were operating a PC.
The standard LAN port allows convenient access to files stored in the internal memory and enables remote updates for firmware from a PC.
Note: All specifications are valid under the following conditions unless otherwise stated: 23˚C ±3˚C, after warming up for 1 hour or more, pulsed light measurement mode off, high dynamic range mode off, horizontal scale: wavelength, and vertical scale: absolute power.
|Reduced emission of CO2 about 74% compared to the previous model.

The university's researchers needed a faster and more efficient and practical solution to measure the spectral performance of lasers and optics beyond traditional telecom wavelengths. To achieve this, they contacted Yokogawa Test&Measurement and collaborated to develop a breakthrough grating-based optical spectrum analyzer that could cover MWIR wavelengths up to 5.5 um. Click to learn how productivity in the research lab dramatically increased for precise characterization of laser sources, and active/passive optical components in the fields of communications, medical diagnosis, advanced optical sensing, and environmental and atmospheric sensing.
The extreme test requirements of our research called for an OSA with extended MIR spectrum bandwidth capabilities up to 5μm, but we couldn’t find one on the market capable of measuring optical inputs at these wavelengths. Yokogawa Test&Measurement rose to the challenge and developed a new OSA model for us that would. Not only do we now have an instrument that is practically custom-made for our needs, it provides repeatable, accurate, and trusted measurement outputs and is easy to learn and use. Their equipment and ability to create a new optical measurement solution has definitely increased the overall efficiency and productivity of our research team.
