Optical test equipment or optical measuring instruments are used to measure and characterize the physical properties of light. The insatiable demand for higher capacity in communication networks has fueled the need for highly precise optical test solutions. In addition, precision optical measurements are essential to optical research applications for biophotonics, environmental sensing, and consumer products.
R&D engineers, academic researchers, manufacturing engineers, and field service personnel depend on precision optical test equipment to ensure design and performance specifications, production quality, and network health. For more than thirty years, Yokogawa (formerly Ando) has delivered quality, consistency, ease of use, and market leadership for optical test applications.
An Optical Spectrum Analyzer (or OSA) is a precision instrument designed to measure and display the distribution of power of an optical source over a specified wavelength span. An OSA trace displays power in the vertical scale and the wavelength in the horizontal scale.
An optical time domain reflectometer (OTDR) is a precision instrument used to locate events or faults along a fiber link, typically within an optical communications network.
An Optical Wavelength Meter measures the peak wavelength(s) of an optical signal with extreme picometer and sub picometer accuracy.
A modular test platform with a wide selection of modules allows optimal configuration of test solutions for optical component and network systems manufacturing.
A compact portable light source and optical power meter are crucial tools to test and verify that insertion losses are within specifications in fiber links deployed by cable TV, enterprise, service provider, carrier, Ethernet and FTTH networks.
This paper describes a compact optical channel monitor and a delayed interferometer having free-space optical elements such as lenses or mirrors, as an application of microoptics. These devices have been developed to be built into dense wavelength division multiplexing (DWDM) transmission systems. These optics use a Gaussian beam which is emitted through single-mode optical fibers and located near the optical axis. This paper explains the optical designs of these devices based on the Gaussian beam's behavior.

Application Xplorer is a Electronic Newsletter that is sent out bi-monthly to inform our customers of our latest news and product applications.
After a disastrous 2009, the large publicly held test companies enjoyed booming business in 2010.
The AQ6370 is Yokogawa's high speed and high performance Optical Spectrum Analyzer for characterization of optical communications system and optical components. Thirteen built-in analysis functions and seven trace calculations for popular applications can be utilized with a simple function key. Yokogawa continues to provide you quality products that simplify your business practices.
The AQ6375 is the first bench-top optical spectrum analyzer covering the long wavelengths over 2 ?m.
It is designed for researchers and engineers who have been struggling with inadequate test equipment to measure in these long wavelength ranges. The AQ6375 achieves high speed measurements with high accuracy, resolution and sensitivity, even while providing full analysis features. Troublesome calibration steps and the development of external analysis software is no longer required.
The AQ7270 OTDR maximizes the total working time during on-site tests as the time to power up the device, make measurements, and analyze and store the measurement results are significantly reduced. The measurement results can easily be transmitted to computers using the USB interface or the Ethernet. The analysis software (optional), helps with preparation of computer-generated reports.
View our webinar on the many uses of an Optical Spectrum Analyzer. This 45 minute presentation covers the basics of light, the design, measurement, and test applications of an OSA.
Learn with Product Manager, Michael Kwok, about crucial fundamental concepts for optical wavelength measurements in this 45 minute session. We will discuss the principles behind optical wavelength measurements of optical sources and devices, as well as basic tips and tricks so you can measure with confidence.
In this webinar, Michael Kwok will discuss general techniques to measure OSNR for both traditional and modulated optical signals. The goal of the webcast is to provide test engineers with key measurement considerations for performing OSNR measurements using an Optical Spectrum Analyzer or OSA.
