Title:
MANUFACTURE OF OPTICAL FIBER COUPLER
Document Type and Number:
Japanese Patent JPH05297241
Kind Code:
A
Abstract:
PURPOSE:To manufacture optical fiber couplers with good yield, which are less dispersive in the photo-transmission loss and also present lesser photo- transmission loss. CONSTITUTION:With an optical fiber coupler concerned, the fusion attached part of an optical fiber bundle 20 is ductilely elongated while heating and fusion attachment are conducted partially with flames given by a movable burner 1, and the optical paths of the optical fibers are coupled together. In manufacturing this type of optical fiber coupler, a movable burner 1 is reciprocated in the elongating direction of the optical fiber bundle 20, at a speed greater than the elongation speed, while the fusion attached part is heated. It will favor if the speed of burner 1 in reciprocation is 1.5-30 times as large as the elongation speed of the fiber bundle 20.
