摘要： PURPOSE: To produce inexpensively an optical fiber which is of a low loss and has high strength and reliability by forming a plasma polymerized film coating between a glass fiber and resin coating.
CONSTITUTION: The plasma polymerized film coating 2 is formed between the glass fiber 1 and the resin coating 3. The base material 4 of the optical fiber is drawn by a drawing furnace 5 to the glass fiber 1 having a required diameter and is introduced into a vacuum vessel 7 for plasma polymn. A gaseous raw material such as ethylene is supplied into the vessel and the plasma polymerized film is formed on the fiber during the passage between counter electrodes 11a and 11b in the state of the prescribed vacuum. The fiber is taken up on a bobbin 17. The fiber coated with the excellent plasma polymerized film to about 0.1μm in the above-mentioned manner has no residual stress and obviates substantially the generation of the transmission loss. The strength is considerably improved and the inexpensive production of the highly reliable fiber is made possible.

The respective members are formed with round grooves 1C, 1C' for contg. optical fiber cores 2 and a juncture 3 are formed to the planes thereof. The member 1 is molecular-oriented in the longitudinal direction thereof. The optical fiber juncture 3 is set into the round grooves 1C', 1C' of the reinforcing members 1A, 1A and thereafter the member 1 is contained into a jug 5 contg. a heater 4 and is heated for a short period to melt the member 1 and to reinforce the juncture. The orientation of the member 1 consisting of the oriented melt-liquid crystalline resin is not annihilated even if the member is heated and melted at a high temp. as far as such heating is for the short period. The low coefft. of linear expansion in the orienting direction is thus maintained.

摘要： PURPOSE:To measure accurate bending rupture strain without using any long- sized test-piece nor passing light by allowing an oscillation sensor to detect a sound or oscilltion generated when an optical fiber ruptures. CONSTITUTION:The opticak fiber 1 is bent and sandwiched between two parallel flat plates 2 and 2', and the flat plate 2' is moved by a motor 3 at a constant speed. The sound or oscillation that the optical fiber 1 generates when rupturing is detected by the oscillation sensor 8 fitted on a flank or the back surface of the flat plate 2 in contact and inputted to a switch circuit 12 through an amplifier 9, filter 10, and detector 11. The circuit 12 when receiving a necessary input owing to the rupture in the optical fiber 1 stops the motor 3 in the driving state afterward, and bending rupture strain is calculated from the currnt distance between the flat plates 2 and 2'. Frequency characteristics of the oscillation sensor 8 and filter 10 are selected to take a test even in a measuring chamber where there is no sound insulating facilities opecially without mulfunction.
