Abstract

PURPOSE:To increase the mechanical strength of a connected optical fiber, by carrying out a surface treatment by dipping the melt-struck connection part of the optical fiber in a treating liquid of strong acid and then in a treating liquid of hydrofluoric acid. CONSTITUTION:A treatment liquid 6 of a mixture solution consisting of 1 or >=2 kinds of strong acid such as sulfuric acid, hydrochloric acid, nitric acid, etc. is stored in a liquid tank 7. A melt-stuck connection part 5 of end parts 2A and 2B of optical fibers 1A and 1B is dipped in the tank 7. Thus coat residue, dust, metallic particles, etc. sticking to the surface of the part 5 are removed. Then the part 5 is dipped in a treating liquid containing an aqueous solution of hydrofluoric acid, ammonium fluoride, sodium fluoride in a liquid tank 8. Thus the minute flaws on the surface are removed or annealed. As a result, the strength is increased at the part 5.
