がある。The commonly used method for connecting optical fibers is to remove all the fiber coating and perform discharge fusion.
The ease with which the coating can be removed (hereinafter referred to as peelability) has a great effect on the workability during connection and the mechanical strength of the joint. That is, if the coating is not completely removed, the burnt and carbonized coating material accumulates on the glass surface due to the discharge, resulting in surface defects that cause a decrease in the strength of the glass fiber. Furthermore, in order to simplify the connection work, it is necessary to omit the work of cleaning with a solvent or wiping with gauze after removing the coating.

および５次元に架橋した形状となる。Currently, curable organopolysiloxane compositions, particularly phenylpolysiloxane compositions, which are most commonly used as V12 cover for the innermost layer of optical fibers, have good wettability to glass, and are also resistant to the effects of moisture in the air. It has a fairly strong bonding force with the glass surface because hydrogen bonding occurs due to silanol groups between it and the glass surface. Therefore,
When removing the outermost nylon gold layer using a peeling jig such as Nornick, it is difficult to completely remove the innermost organopolysiloxane composition layer at the same time, and it is necessary to wipe the glass surface again with gauze soaked in alcohol. There is. At this time, the glass surface is damaged, and the strength of the connection portion is reduced to Y average 500 to 700 f (125 μm outer diameter phino()). The purpose of the present invention is to provide a coating structure with good peelability (peelability) from glass fibers and a method for manufacturing the same. Composition t-apply, then
A cured glass fiber for light transmission, characterized in that a non-reactive organopolysiloxane of 20% by weight or less is added to the curable organopolysiloxane composition, and its production. The curable organopolysiloxane composition (silicon resin) used in the present invention is a so-called Calo reaction type RTV silicone rubber, and mainly contains (6)
An organopolysiloxane capped with vinyl terminals represented by the general formula % (where R has no aliphatic unsaturated bond)
Substituted monovalent hydrocarbon groups, such as saturated alkyl groups such as methyl groups and aryl groups such as phenyl groups), (b) 6 hydrogen atoms directly bonded to a silicon atom in one molecule.
(c) a catalytic amount of a platinum compound; after curing, component (0) becomes two-dimensionally and five-dimensionally crosslinked by component (b).

。In addition, in the non-reactive polysiloxane to be added in the present invention, the terminal vinyl moiety of the curable organopolysiloxane component (a) is replaced with a saturated alkyl group such as a methyl group or an ethyl group, and the terminal 'fI: is blocked. It is of molecular weight.

Further, there is no particular restriction on the curing method, and any of heat, ultraviolet rays, and electron beams may be used.

という本来の目的をはだすこ七ができない。By adding the above non-reactive organopolysiloxane, after the curable organopolysiloxane composition is cured, the non-reactive organopolysiloxane oozes out at the interface between the glass fiber and the cured organopolysiloxane composition layer. By forming a film, the peelability of the organopolysiloxane composition layer is significantly improved, and when the outermost layer of nylon is removed without nicking, the removal force can be completely removed at the same time. In order to fully exhibit the oozing effect, it is desirable that the non-reactive organopolysiloxane composition has an average molecular weight of 104 or less and a viscosity of 400 apO or less. The amount of non-reactive organopolysiloxane to be added is required to be at least 20 Oppm, and for the purpose of exhibiting the oozing effect, more is better, but if it is 20% by weight or more, the organopolysiloxane after curing is Inhibits the q nature of the composition. Specifically, it has low mechanical strength and cannot fulfill its original purpose of protecting the glass surface.
