Embodiment Construction

[0027] The present invention is described in more detail below in conjunction with accompanying drawing example:

[0028] combine figure 1 , the preparation process of the parallel array optical fiber preform is as follows: first, the high-purity quartz glass rod is cut in half along the diameter direction with a glass cutting machine to obtain two semi-cylindrical quartz glass rods. The cut surfaces of the two quartz glass rods are then ground to form two D-type glass quartz rods 1 . The ground-off dimensions of the two D-glass rods should be the same, and the sum of the ground-off dimensions of the two D-glass rods should be equal to the diameter of the optical fiber core member to be inserted. Take the specially prepared optical fiber ferrule member, and cut out several sections of the same length of the optical fiber core member in sections. The optical fiber core components 2 are filled between the two D-shaped glass rods, so that the optical fiber core components are a...

Abstract

The invention provides a parallel array multi-core fiber and a preparation method thereof. Firstly, specially prepared fiber core filigree member is sectionally cut out according to certain length to obtain a group of fiber core filigrees with the same standard performance; the group of fiber core filigrees is tightly adjacent and is clamped between two high purity semi-column structure silica glass members, and is inserted into a high purity quartz outer sleeve after combination, so that a parallel array fiber core fiber preformed bar is formed; the group of the fiber core has the same axial direction with the quartz outer sleeve, and is positioned at the diameter position of the end face of the quartz outer sleeve; one end of the parallel array fiber core fiber preformed bar is sintered and sealed by high temperature oxyhydrogen flame, and then drawn into parallel array core fiber on a fiber wire-drawer-tower; in the process of fiber wire-drawing, a negative pressure is applied at the other end of the fiber preformed bar that is non-sintering end. The processing size is easy to control and the processing technology is simple and convenient, so the technology used for preparing the whole fiber preformed bar is simple, convenient and reliable, and has good economical efficiency.

Description

(1) Technical field [0001] The invention relates to an optical fiber and a preparation method thereof, in particular to a parallel array multi-core optical fiber and a preparation method thereof. (2) Background technology [0002] A multi-core optical fiber in the usual sense refers to an optical fiber formed by placing a group of axially parallel multiple optical fiber cores in an ordinary optical fiber cladding. The optical properties of this multi-core fiber are achieved by directing light into multiple fiber cores. Generally, the diameter of a single fiber core is between a few microns and tens of microns, and the outer diameter of the entire fiber is 125 μm. In order to obtain the required light transmission characteristics of the optical fiber, the fabrication of the optical fiber preform usually adopts the deposition of elements such as germanium and phosphorus in the ordinary quartz matrix material, so that the refractive index of the optical fiber core is higher th...
