Side-pass optical fiber processing device and method of use thereof

Abstract

The invention discloses a side-pass type optical fiber processing device, which comprises a winding reel main body and an air intake cover, and the winding reel main body and the air intake cover are respectively provided with matching sealing structures; the middle part of the winding reel main body is provided with a hollow central shaft , there is also a ventilation hole on the central shaft, and an air outlet is also provided at the end of the central shaft; the sealing structure on the main body of the winding disc is a card slot opened on its side wall, and the number of the card slots is two , and are respectively arranged on both sides of the main body of the winding disc in a ring shape, and a sealing ring is also arranged in the card groove; the air intake cover includes an air intake interface, an air intake bucket, a fixed wrapping bucket and an overturned wrapping barrel. The invention provides a side-through optical fiber processing device, so that the air between the optical fibers can be better discharged, and D2 is better wrapped on the optical fiber while the air is discharged, which greatly improves the processing efficiency and the optical fiber. Quality has promoted the development of the industry and the growth of the enterprise.

Description

technical field [0001] The invention relates to an optical fiber processing device and its use method, in particular to a side-through optical fiber processing device used in the optical fiber manufacturing process. Background technique [0002] At present, optical fibers need to pass D 2 Treatment is carried out to eliminate the hydroxide absorption peak (commonly known as water peak) near 1380nm, and the usual treatment process is to place the optical fiber wound on the take-up reel in a treatment tank with constant pressure for a certain period of time. Contains D 2 , using D 2 The free movement of molecules gradually permeates around the optical fiber, and combines with the Si-O-broken bond in the optical fiber to form a stable Si-O-D. The bonding energy of the deuterium-oxygen bond is greater than that of the hydrogen-oxygen bond, so that the hydroxyl radical can be avoided formation, so that the hydroxide absorption peak near 1380nm (commonly known as the water peak...

[0002] At present, optical fibers need to pass D 2 Treatment is carried out to eliminate the hydroxide absorption peak (commonly known as water peak) near 1380nm, and the usual treatment process is to place the optical fiber wound on the take-up reel in a treatment tank with constant pressure for a certain period of time. Contains D 2 , using D 2 The free movement of molecules gradually permeates around the optical fiber, and combines with the Si-O-broken bond in the optical fiber to form a stable Si-O-D. The bonding energy of the deuterium-oxygen bond is greater than that of the hydrogen-oxygen bond, so that the hydroxyl radical can be avoided formation, so that the hydroxide absorption peak near 1380nm (commonly known as the water peak) can be eliminated. This process usually takes more than 20 hours. The biggest disadvantage of such treatment is that under constant pressure, it is difficult to remove the remaining in the gap between the optical fibers. air out, let D 2 effectively wraps around the fiber

And with the improvement of optical fiber production technology, more and more optical fibers are wound by the take-up reel, which seriously affects the D 2 The efficiency and quality of processing are not conducive to the development of the industry and the growth of enterprises
