Title: Method for connecting equal-diameter optical fibers
Inventor: KURAMOCHI MASANORI
IPC: G02B6/24
Filed: 1990-03-13
Abstract: PURPOSE:To allow same-diameter connection without having the possibility of flawing glass fibers by providing a carbon coating layer on the outer periphery of the glass fiber consisting of a core and a clad and providing a buffer coating layer on the outer periphery thereof. CONSTITUTION:The carbon coating 2 is applied on the outer periphery of the glass fiber 1 by which the fiber is constituted as the carbon coated fiber 4. The UV resin coating 3 is applied as a buffer material on the outer periphery thereof. Since the carbon film 2 exists on the lower layer of the UV resin 3, there is no possibility of flawing the glass fiber 1 even if a clamper 5 is directly pressed to the carbon coated fiber 4. The micromovement of the exposed fiber is, therefore, rapidly stopped and the immediate execution of centering and fusion splicing is possible if the carbon coated fiber 4 can be fixed by the clamper 5. The same-diameter connection efficiency is improved in this way.
