Visando expandir as oportunidades de negócios de instrumentos de teste e medição, a Yokogawa adicionou um foco específico na área de redes de comunicação ótica. Esse foco levou a parceria e posterior aquisição da Ando Electric. Esta combinação estratégica da profunda experiência da Ando em instrumentos de teste óticos desde 1980 e o foco e perfil da Yokogawa como empresa de instrumentos de teste e medição desde 1915, gerou um fornecedor altamente qualificado para a indústria de redes óticas, sustentável mesmo em tempos difíceis no mercado.
A parceria estratégica da Yokogawa com a Ando proporcionou o fornecimento de instrumentação espectral de precisão, fundamental para a implantação de sistemas CWDM e DWDM. Como a Ando foi incorporada à explosão inicial da demanda óptica, nossos analisadores de espectro óptico ajudaram a acelerar o rápido desenvolvimento da capacidade intensa transferência de dados.
Hoje, olhamos para o futuro e continuamos a inovar com instrumentos tais como medidores de comprimento de onda, analisadores de espectro ótico - OSA, sistemas de medição e testes modulares e OTDR’s multitarefas.
Dentre as principais aplicações neste segmento destacam-se:
- Análise de redes óticas PON/GPON: através dos OTDR’s AQ7280 e AQ1210 com medição de fibra ativa;
- Monitoração e manutenção de redes óticas: OTDR compacto série AQ1000;
- Medição de OSNR em DWDM e CWDM: linha de analisadores de espectro ótico série AQ6370;
- Avaliação de sistemas DWDM e CWDM: medidores de comprimento de onda série AQ6150B;
- Sistemas de Teste GE-PON: linha de plataformas Multi-Teste série AQ2200.
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.
