力が加わり、lIr1l!する危険がある。As a method for connecting optical 7-eyeliner fibers, there is a so-called fusion splicing method in which the optical 7-eyeliner fibers to be connected are butted together and then heated and fused. In this case, it is necessary to remove the plastic covering layer of the optical fiber core, which serves to maintain the mechanical strength of the optical fiber core. For this reason, after light 7 Aipashin m* continuation,
It is necessary to reinforce the removed part of the covering layer. This contact M, l
As a reinforcing method for 111, it has been proposed to use a plastic reinforcing member. However, the S* elongation of the optical 7-A5 fiber core wire is very small (10"1-10-/"
C) There is almost no effect of temperature envy, whereas the reinforcing member is plastic and its ms elongation is large <io''S~1
0-'/''C), since the influence of temperature change is large on non-S,
When stress such as heat is applied, the reinforcing member expands and contracts. This allows localization of the optical fiber core.
This causes an increase in transmission loss, and furthermore, fiber breakage occurs due to the protrusion of the optical 7-iper core wire. In addition, the elasticity of the plastic reinforcing member is made of several hundred to i, ooo, and is smaller than the elastic modulus of the Hikari 7 Aiper core wire, which is 7.000Y;tK, so the reinforcing member is easily deformed by external force, and the Stress is applied to lIr1l!

Stretching stress effectively works to enable stretching and orientation of high-strength fibers, allowing the elastic modulus to be high and the elasticity to be small. Transparent plastic pipes made of polymers that are difficult to bond, such as polyethylene-polyethylene terephthalate, can be made using a 111-100-degree plasma treatment process using gases such as helium or helium.
