Um reflectômetro ótico no domínio do tempo (OTDR) é um instrumento de precisão normalmente usado para localizar eventos ou falhas ao longo de um link de fibra ótica, dentro de redes de comunicações óticas. O OTDR lança uma série de pulsos óticos de alta velocidade na fibra a ser medida. Vários eventos na fibra geram uma dispersão de Rayleigh que retorna ao OTDR e a força dos pulsos de retorno é medida e integrada em função do tempo, e plotada em função do comprimento da fibra. O eixo horizontal é a distância e o eixo vertical é a perda.
Os OTDRs são usados principalmente no serviço de instalação e manutenção de fibra ótica de redes de acesso (links de comunicação entre centrais telefônicas e postes) e redes de usuários (links de comunicação entre sites de usuários e postes).
Nossa ampla linha de OTDRs oferece excelente relação de custo/desempenho, durabilidade de campo e faixa dinâmica aplicável. Com trinta anos de inovação em projetos de reflectometria, fornecemos soluções de tecnologia onde você mais precisa.
AQ7933 is application software to display and analyze waveform data measured by Yokogawa OTDRs and create a work report on a PC. This software provides more intuitive operability than the conventional software, helping field engineers to reduce their work.
A 12-channel optical switch box that effectively improves workability with YOKOGAWA OTDRs.
Controlled from an OTDR, the OSW allows continuous measurement of all or a subset of the 12 channels.
The compact size makes this an ideal solution to conveniently measure multiple ribbon fibers in the field or conserve production test rack space.

Overview of optical communications via optical fibers including: signal conversion, optical fiber benefits, techniques like wavelength division multiplexing (WDM) for increased capacity, key components like optical amplifiers and spectrum analyzers for maintaining transmission quality.
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.
