Optical Converter for Lower Frequency Application
Regarding the research about characteristics of a substances occurred under ultra-high-magnetic-field, it is required to do measuring under environment of electromagnetic noise. Also, it is quite hard to do measuring avoiding common-mode by electromagnetic-induction or ground loop, which spend you a lot of time on coping with. Even if you connect output from sensor part with a shielded cable and install a measurement in the place where there is no infulence of noise, noise could be induced to the shielded cable.
So, introducing low-frequency-RoF, you can take advantage of characteristic of optical fiber, which means high-isolation, convert output signals from sensor into optical signals and do transmission. It makes you possible to avoid influence of electromagnetic noise and create ideal environment for measuring.
