Optical test equipment or optical measurement equipment 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.
What is a spectrum analyzer? See related Products, Yokogawa Optical Spectrum Analyzer for AQ63 Series optical analyzer specifications, the spectrum analyzer definition, and the operating principles of optical equipment.
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 system does not require manual reconfiguration of optical paths and adjustments of EDFA input power, and that improves measurement throughput and avoids a human error.

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.

We have developed the AQ2200-136 compact tunable laser source module with a wide wavelength range of 200 nm (1440 to 1640 nm) and a maximum output power of +7 dBm or greater, as a plug-in module for the AQ2200 multi-application test system (MATS). When combined with the AQ2200 series of optical sensors or the AQ6317B/C/AQ6319 optical spectrum analyzer, the AQ2200-136 enables users to measure the wavelength-dependent loss (WDL) of an optical device without any personal computers. In this paper, we describe the features and structure of the AQ2200-136.
We have developed the AQ6375 grating-based desktop optical spectrum analyzer, which can measure an optical spectrum over a wide wavelength range from 1.2 to 2.4 m with high wavelength resolution at high speed. Despite the popularity of desktop optical spectrum analyzers in the telecommunication wavelength region, a large-scale optical spectrum measurement system with a monochromator has commonly been used for measuring the long wavelength region, and so there was a need for a desktop optical spectrum analyzer for long wavelengths. Deep optical absorptions appearing in the long wavelength region around 2 m caused by CO2, NOX and H2O are attracting attention in the environmental and medical fields, and thus sensitive measuring equipment by laser absorption spectroscopy using a near infrared semiconductor laser is becoming more popular. With excellent optical spectrum measurement capabilities (high resolution and high speed), operability and maintenance performance, the AQ6375 optical spectrum analyzer will contribute to the performance improvement and spread of near-infrared semiconductor lasers used in laser absorption spectroscopy.
With improvements in the speed and bandwidth of communication networks in recent years, 10-Gbit/s high-speed optical communications systems are becoming increasingly widespread in core networks, as well as access networks and LANs. Accordingly, devices and modules for use in 10-Gbit/s transmission are being actively developed, causing increasingly fierce price competition. Under these circumstances, the bit error rate testers (BERT) necessary to test these devices and modules are also facing a demand for lower prices. We have explored essential functionality and performance and examined product specifications, with a focus on application to the production of optical transceivers. Consequently, we have developed two compact and economical 10-Gbit/s BERTs, a plug-in module model and a portable model, featuring variable amplitudes, cross-points and voltage offsets for the data output and a built-in clock and data recovery (CDR) function.
Improving and optimizing electric motor performance and efficiency depends on understanding how electric current is measured.
The 40-Gbit/s transport networks that will meet the communication demand of Next-Generation Networks (NGN) are starting to be deployed commercially. To meet the increasing measurement needs of the 40-Gbit/s networks and transmission equipment, we have developed the NX4000 Transport Analyzer. This can accurately and efficiently measure the transmission quality and characteristics of the networks, transmission equipment corresponding to 40-Gbit/s Synchronous Digital Hierarchy (SDH), Synchronous Optical NETwork (SONET), and Optical Transport Network (OTN). This paper describes the various measurement applications of the NX4000 Transport Analyzer.

After a disastrous 2009, the large publicly held test companies enjoyed booming business in 2010.
One of the challenges for engineers involved with the development or maintenance of complex electromechanical systems is to link the behavior in one part of a system to control signals in another. In particular, engineers often need to understand causality: the relationship between an event (the cause) and a second event (the effect) to obtain an insight into an electromechanical system’s overall behaviour and to plan corrective actions accordingly.
No, unfortunately due to the number of current fiber combinations, we do not stock optical fibers. There are many companies that specialize in optical fiber cords.

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.
The AQ7933 OTDR Emulation Software is software that can re-analyze and create reports of trace data measured on a Yokogawa OTDR.
It is more intuitive than conventional software and has a wealth of useful features including event map and pass / fail judgment screen.
