。[Detailed description of the invention] The present invention is a plastic clad glass fiber for optical transmission.
In particular, the present invention relates to a plastic clad glass fiber for optical transmission which has excellent oil resistance and solvent resistance.

Plastic clad optical fibers whose cladding layer is made of silicone resin have been put into practical use for relatively short-distance optical transmission.

れらの油や溶剤は、屈折率が１４５を越えるものが多い
ので、浸漬後のクラッド層の屈折率が上昇してしまう。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.
これらによって、光ファイバの伝送損失が大きくなり、
また、光ファーｆパが破断しやすくなることが容易に想
定される。These increase the transmission loss of the optical fiber,
Furthermore, it is easily assumed that the optical fiber becomes more likely to break.
