2. Compact Design: With a footprint approximately half the size of the AQ6370E, the AQ6361 is designed to save valuable bench space. Its compact form also makes it ideal for integration into laser diode chip testers and other test systems.

3. Superior Optical Performance: The AQ6361 provides a wavelength resolution of 0.03 nm and covers a wavelength range of 1200 to 1700 nm. It also delivers high dynamic range measurements with exceptional stray light suppression of 73 dB, making it versatile for testing a wide range of optical modules.

Target Markets

• Manufacturers of optical communication devices, modules, and silicon photonics devices

• Laser diode testing systems

Applications

• Characterization testing and product evaluation in the production of optical components, including lasers, optical transceivers, and optical amplifiers

Yokogawa Test & Measurement Corporation has introduced the AQ7290 Series Optical Time Domain Reflectometer (OTDR), designed to enhance the installation and maintenance of optical communication networks. With six models offering two or three wavelength configurations, the series delivers improved reliability, usability, and accuracy.

As the flagship model in Yokogawa’s OTDR lineup, the AQ7290 Series prioritizes ease of use. It features a multi-touch screen, an updated graphical user interface, and a simplified OTDR mode for one-button measurements. A USB Type-C power option allows operation via mobile battery, ensuring field technicians can respond to service calls efficiently.

Performance enhancements include an increased dynamic range—up to 2 dB higher than its predecessor—allowing for longer-distance measurements. The high-reflection real-time measurement mode improves waveform clarity, making it easier to assess long-distance routes and complex network structures.

The AQ7290 also supports remote operation via wireless LAN adapters and LTE USB dongles, enabling technicians to manage tests from offsite locations.

Targeting telecommunications carriers, network service providers, and infrastructure companies, the AQ7290 Series offers an advanced solution for fiber-optic network deployment and maintenance.

Drawing on decades of technological expertise and experience in the field, Yokogawa presents the AQ6370E optical spectrum analyzer. This cutting-edge instrument is designed to address the growing demand for highly accurate and user-friendly test equipment in the research, development, and production of optical communication devices and equipment. The surge in Cloud services, 5G communications, and other information and communication services necessitates robust and high-speed optical communication networks, thereby propelling the need for next-generation optical devices and components capable of supporting these networks. To evaluate the characteristics and quality of these advancements, precise optical test instruments are indispensable, enabling analysis of light wavelength components and measurement of wavelength characteristics.

Since its initial release in 2014, Yokogawa's AQ6370D optical spectrum analyzer has gained widespread adoption in both R&D and production testing. The newly launched AQ6370E builds upon its predecessor by introducing a range of innovative functions and features that streamline development and production processes.

Among the notable enhancements is the High Close-in Dynamic Range (HCDR) mode, which empowers users to measure single longitudinal mode lasers with exceptional close-in dynamic range. Close-in dynamic range plays a vital role in laser and optical device development.

Furthermore, the AQ6370E offers a Side Mode Suppression Ratio (SMSR) mode that reduces measurement time for SMSR and an Application (APP) mode tailored for specific device under test (DUT) interfaces. The APP mode guides users seamlessly through configuration settings to test result outputs, making it easily accessible even for customers unfamiliar with optical spectrum analyzers.

Another notable addition is the large LCD touch screen, enhancing everyday operation of the analyzer with its intuitive and user-friendly interface.
