Yokogawa launches extreme precision Optical Spectrum Analyzer
AQ6380 features improved precision and productivity for developing next generation optical network backhaul components –
Yokogawa has launched a new optical spectrum analyzer (OSA) designed to offer the extreme high precision demanded by researchers developing the next generation of optical communication components.
With the exponential growth in the Internet of Things, as well as cloud computing services, video broadcasting and conferencing, and the rise in access to mobile broadband, demand for data capacity will expand hugely over the next few years. High capacity optical backhaul networks will be needed to serve this growing traffic density. Dense wavelength division multiplexing (DWDM) is an optical multiplexing technology used to increase bandwidth over the existing fiber network.
As data hungry applications push the performance requirements of DWDM systems, telecommunication channels become ever more closely spaced, making it more difficult to separate the individual channels in the wavelength division multiplexing (WDM) analysis on an OSA.
The Yokogawa AQ6380 OSA offers unequaled optical performance to allow engineers and scientists to develop and improve the speed, bandwidth and quality of the next generation of communication networks, while its ease of use ensures it can be operated quickly and efficiently.
“The AQ6380 is demonstrably the world’s best grating based OSA, outperforming its nearest competing solution on wavelength accuracy, resolution, dynamic range, and actual measurement speed,” says Terry Marrinan, Yokogawa Test & Measurement's Vice President, Marketing.
“The new product also offers a highly capable alternative to other measurement technologies, comparing favorably on wavelength range and actual dynamic range, and offering superior measurement speed and application adaptability, as well as a highly competitive price.”
The AQ6380 has excellent optical wavelength resolution down to 5 picometers (pm), allowing optical signals in close proximity to be clearly separated and accurately measured. With the AQ6380, waveforms that were previously not even visible in a typical OSA, such as modulation side peaks in the laser spectrum, can now be accurately visualized.
It also offers a wavelength range of 1200 to 1650 nm, allowing one unit to meet diverse wavelength measurement needs. With the ability to alter the wavelength resolution from 5 pm to 2 nm, a wide range of applications can be supported, from narrowband peak/notch measurements to wideband spectral measurements.
A major challenge for optical researchers has been maintaining the accuracy of their instruments, with ambient temperature change, vibrations, and shock all potentially affecting the measurement accuracy of optical spectrum analyzers.
To maintain consistently high accuracy, the AQ6380 features on board calibration based on a built-in light source. Wavelength calibration is automatically performed at set intervals by switching the optical path with an internal optical switch.
Another important parameter in optical waveform analysis is close-in dynamic range, defined as the difference in power level measured from the peak of the signal to the noise at a specific distance from the peak wavelength.
The AQ6380 features a newly designed monochromator with sharper spectral characteristics than previously available, achieving a close-in dynamic range of up to 65 dB. The result is that signals in close proximity can be clearly separated and accurately measured.
The new monochromator also offers very high stray light suppression, an important criterion in optical measurement. For example, in situations such as laser SMSR measurement, where several optical spectra with different levels are measured at the same time, the stray light may interfere with the measurement. The AQ6380 offers a best-in-class stray light suppression value of 80 dB.
Fast measurement speed is another major benefit, with the AQ6380 capturing data points in only 0.23 seconds compared to 5.4 seconds for the existing model (AQ6370D) in certain conditions.
The new AQ6380 is also designed for ease and efficiency of use, ensuring the measurement scheme can be set up rapidly and data can be acquired easily.
The high-resolution, responsive 10.4-inch touchscreen LCD makes the device as easy and intuitive to operate as a tablet.
When it comes to analyzing results, the AQ6380 has built-in analysis functions to characterize optical spectrum from a variety of optical systems and devices, such as WDM system, DFB-LD, EDFA, and filters.
Analysis functions include: DFB-LD; FP-LD; LED; Spectral width (peak/notch); SMSR; Optical power; WDM (OSNR); EDFA (Gain and NF); Filter (peak/bottom) and WDM filter (peak/bottom).
The AQ6380 also features an application menu “APP mode”, which makes measurement set-up much easier. Pushing the APP button brings up an overview of the pre-installed testing apps – WDM, DFB-LD, FP-LD and LED testing. A guide through wizard leads the user through an easy set up process for specific measurements and analysis.
New or additional testing applications will be made available for download from the Yokogawa website and can be added to the AQ6380 by future firmware updates.

About Yokogawa Test & Measurement
Yokogawa has been developing measurement solutions for over 100 years, consistently finding new ways to give R&D teams the tools they need to gain the best insights from their measurement strategies. The company has pioneered accurate power measurement throughout its history. Today, with more than 30 years of experience in optical testing, Yokogawa offers a broad range of optical instruments and is the market leader for Optical Spectrum Analysers in research and test laboratory environments.
Yokogawa instruments are renowned for maintaining high levels of precision and for continuing to deliver value for far longer than the typical shelf-life of such equipment. Yokogawa believes that precise and effective measurement lies at the heart of successful innovation – and has focused its own R&D on providing the tools that researchers and engineers need to address challenges great and small.
Yokogawa takes pride in its reputation for quality, both in the products it delivers – often adding new features in response to specific client requests – and the level of service and advice provided to clients, helping to devise measurement strategies for even the most challenging environments.
The guaranteed accuracy and precision of Yokogawa’s instruments results from the fact that Yokogawa has its own European standards laboratory at its European headquarters in The Netherlands. This facility is the only industrial (i.e. non-government or national) organisation to offer ISO 17025 accredited power calibration, at frequencies up to 100 kHz: a requirement for higher harmonic measurements specified in quality standards such as ISO 9000.
