However, silicone resin can be used for transformer oil, cable oil,
It has the disadvantage that it swells when immersed in hydrocarbon oils such as lubricating oils or hydrocarbon solvents. When a conventional silicone resin-clad optical fiber comes into contact with these oils or solvents, the adhesion between the core and the clad layer decreases significantly, and in some cases, the optical fiber may peel off. Unfortunately, many of these oils and solvents have refractive indexes exceeding 145, so the refractive index of the cladding layer after immersion increases.

Furthermore, it is easily assumed that the optical fiber becomes more likely to break.
