Medidor de Comprimento de Onda Ótico

Um medidor de comprimento de onda ótico mede o(s) comprimento(s) do pico de onda(s) de um sinal ótico com extrema precisão, geralmente com precisão de picometro ou melhor.

O uso da comprovada tecnologia de interferômetro Michelson, juntamente com um algoritmo FFT avançado, permite a medição de sinais modulados e não modulados de um transceptor ótico. Um monitor flexível pode medir e exibir um ou vários comprimentos de ondas (como de um sistema DWDM) em uma única operação.

Nosso medidor de comprimento de onda ótico oferece o primeiro laser de referência interno de vida útil prolongada do setor, para maximizar o tempo de uso entre tarefas de manutenção intrusivas na exigente pesquisa e desenvolvimento ótico de alta velocidade de hoje, bem como em aplicações de fabricação.

The AQ6150B measures the wavelength and power levels of both CW and Modulated optical signals from transceivers and WDM transmission systems.

  • AQ6151B optical light wavelength meter
  • Wavelength and power level of CW and modulated optical signals from tunable lasers and DWDM transmission systems
  • Range: 900 to 1700 nm
  • Accuracy: ±0.2 ppm
Visão Geral:

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.
