摘要： PURPOSE:To observe simultaneously both end faces of optical fibers facing each other, by forming mirror faces in the end part of a butting rod in two directions facing each other at about 45 deg. to the axis of the butting rod. CONSTITUTION:Optical fibers 1 and 1' are brought into contact with both side faces of a butting rod 9 where mirror faces 10 and 10' are formed in two directions facing each other at 45 deg. and optical fibers 1 and 1' are positioned. Thereafter, the butting rod 9 is allowed to fall, and mirror faces 10 and 10' are placed between end faces of optical fibers 1 and 1'. When they are observed by a microscope 4 provided above the butting rod 9, side faces 12 and 12' of optical fibers 1 and 1' and images 11 and 11' of end faces of optical fibers 1 and 1' projected to mirror faces 10 and 10' are observed in the visual field. In this case, lengths l and l' from the center of the visual field to images 11 and 11' are measured and are compared with each other to discriminate whether they are equal to each other, thereby confirming whether optical fibers 1 and 1' are shifted axially or not.

摘要： PURPOSE:To prevent the sticking between a heater and a heat-shrinkable tube after cooling and to facilitate their separation by winding a nonadhesive sheet around the surface of the heater which heats the heat-shrinkable tube of the melt-sticking connection part of the optical fiber. CONSTITUTION:The heat-shrinkable tube 3 made of polyethylene for reinforcement of the melt-sticking connection part of an optical fiber core 2 contacts the top surface of the heater 1, but the sheet 4 of a 0.1mm. thickness nickel silver sheet whose one surface is coated with ''Teflon'' to a 30mum thickness is wound around the heater surface. This method which utilizes the nonadhesiveness of this ''Teflon'' coat requires only an about 80g force for separation after cooling as compared with an about 500g force in a coventional method, and the sticking force is almost eliminated when the heater temperature is held at 60 deg.C, obtaining great effect on operativity and reliability.
