In today's digital era, the telecommunications industry is continuously evolving to meet the relentless demand for high-speed, reliable networks. Optical technologies connect the world with unparalleled efficiency. From vast fiber-optic networks to cutting-edge photonic devices, it drives innovation and shapes the future of global connectivity.
Since its acquisition of Ando in 2002, Yokogawa has been innovating precision test solutions for the design, validation, manufacturing, installation and maintenance of optical components and network equipment.
The Trusted Benchmark For Optical Analysis
The Measurement Challenge
Various measurements along an optical network path require specialized equipment optimized to ensure the highest quality with few trade-offs. The correct instrument may depend on the level of accuracy, number of channels, or type of signal being acquired.
Optimizing bias voltage is essential for efficient optical modulator operation, maintenance of signal quality, and meeting performance specifications required for a designated application. Proper biasing helps achieve desired modulation effects, reduces distortion, and enhances overall reliability of optical communication systems.
This application note introduces free space light measurement jigs for measuring the emission spectrum of a light source that propagates in free space or the optical transmission spectrum of an optical filter. It describes four types of jigs for light sources and one type for filters.
Optical transceivers are one of the indispensable key devices for optical communications that interconvert optical and electrical signals.
To accurately measure pulsed light using an optical spectrum analyzer (OSA), it is necessary to understand the characteristics of the OSA and select the appropriate measurement method and settings.
We have developed the AQ6375 Optical Spectrum Analyzer 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 optical spectrum analyzer will contribute to the performance improvement and spread of near-infrared semiconductor lasers used in laser absorption spectroscopy.
How-tos
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.
This video will introduce the basic usage of the AQ7933 such as one-way analysis, two-way (bidirectional) analysis, and report creation.
Webinars
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.
