とができない。Conventional optical transmission glass fibers are coated with one or two layers of pre-coat or buffer of silicone resin, epoxy/resin, or fluorocarbon resin on the surface of the glass fiber. It is covered with a reinforcing layer such as fat and has a 7-metal structure and 1-7. However, such a structure speeds up the manufacturing speed and improves [-1-te/l=, d+・1-1] I can't.

題点をもっている。A method of melt-extruding plastic as a reinforcing layer has been proposed, but in order to make the reinforcing layer thinner, it is necessary to strictly control the extrusion electrons by 1, which increases the speed. It is difficult. Second, it has the problem that it is difficult to coat it in the same line as the precoat or buffer layer.

In order to form a foamed resin layer, the reinforcing layer hardens much faster. With this method, it is possible to "manufacture rasphies" for transmission purposes, and productivity can be greatly improved.
