Unparalleled Optical Performance
5 pm (0.624 GHz) high wavelength resolution
The AQ6380 achieves a wavelength resolution of 5 pm. It enables to separate closely allocated DWDM channels and modulation side peaks of optical transceivers.
Modulated spectrum of 10G optical transceiver
65 dB wide close-in dynamic range
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.
Spectrum of external cavity laser
Wide wavelength range and variable resolution support multiple applications
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.
Transmission spectrum of optical filter
80 dB stray light suppression
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.
Stray light suppression performance
Gas purging mechanism to minimize water vapor absorption
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.
Effect of purging
±5 pm wavelength accuracy
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.
Automated wavelength calibration maintains high accuracy
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.
Single-mode fiber input
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.
Advancing Market Capabilities
The extreme test requirements of our research called for an OSA with extended MIR spectrum bandwidth capabilities up to 5pm, 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.

Enhanced function keys
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.
WDM transmission systems
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.
Example of DWDM OSNR analysis
Lasers/optical transceivers
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.
Example of DFB-LD analysis
