の結合も良く、短距離の光伝送分野に用いられている。U. Prior Art] Conventionally, low-loss inorganic glass optical fibers have been known and put into practical use as a medium for long-distance optical communication. On the other hand, optical fibers with synthetic resin cores have features such as being able to have a large diameter and having a large numerical aperture, and also have good coupling with light sources and light-receiving elements, and are used in the field of short-distance optical transmission.

り、これを用いた光伝送体は耐熱性に優れているという
利点を有している。As current synthetic resin core materials, for example, polymethyl methacrylate, polystyrene, etc. are known. Furthermore, in recent years,
The use of a cured organopolysiloxane product as a core material is disclosed in JP-A-57-102604. JP-A-60-436
13. This was proposed in Japanese Patent Application Laid-Open No. 63-121004, and an optical transmission body using this has the advantage of being excellent in heat resistance.
しかしながら、オルガノポリシロキサン硬化物をコア材
料に用いた光伝送体は、高湿度条件で使用すると光伝送
損失か大きくなるという欠点がある。However, an optical transmission body using a cured organopolysiloxane material as a core material has a drawback that the optical transmission loss increases when used under high humidity conditions.
この欠点を補う方法として、実開平１−９７３０５号公

ラスチ・ｙりの遣水層を設ける方法がある。As a method of compensating for this drawback, there is a method of providing a water supply layer made of glass fibers with low water vapor permeability, as disclosed in Japanese Utility Model Application Publication No. 1-97305.

There is a method of taping a metal tape as disclosed in Japanese Utility Model Application No. 61-68213. Another method is to use the optical fiber inside a metal tube that serves as a protective layer.

しかし、前記のプラスチックの遣水層を設けるける方法

高温、高湿度下では光伝送体の光伝送特性が低下して行
き、水蒸気の遮断は不十分であった。However, although the above-mentioned method of providing a water-permeable layer of plastic can prevent the amount of water vapor permeation to some extent, the optical transmission characteristics of the optical transmitter deteriorate under long-term high temperature and high humidity conditions. The water vapor was not sufficiently blocked.
また、金属テープを巻き付ける方法は、テープとテープ
継ぎ目から水蒸気が透過して行き、同じく長時間の高温
、高湿度下での使用は出来なかった。Furthermore, in the method of wrapping metal tape, water vapor permeates through the joint between the tapes, and similarly, it cannot be used for long periods of time under high temperature and high humidity conditions.

ァイバを提供することにある。Furthermore, the method of using optical fibers in metal tubes is
Since there is no bonding force such as close contact or adhesion between the metal tube and the optical fiber, there is a problem in that the optical fiber protrudes or retracts from the metal tube due to temperature cycles. The object of the present invention is to provide a new synthetic resin optical fiber that eliminates the drawbacks and has excellent environmental resistance including moisture resistance.

In this method, organopolysiloxane is injected as a polymer precursor of a core material with a high molecular weight of more than 1.0%, and this is heated and cured to obtain a synthetic resin optical transmission body consisting of a core, cladding, and metal tube.

By using the metal tube as the waterproof (wet) protection 11, the moisture resistance is greatly improved.
