Description
(I) technical field
The invention relates to a device for efficiently inserting optical fibers into a porous capillary tube, and belongs to the technical field of optical fiber device preparation.
(II) background of the invention
In recent years, conventional single mode fiber transmission systems have achieved transmission capacities of up to 100 Tb/s. However, due to limitations in amplification bandwidth, nonlinear noise, and fiber blowing, the capacity of existing conventional single mode fibers has failed to meet the ever-increasing capacity demands and is approaching its 100Tb/s fragrance transmission limit.
The novel space division multiplexing technology using the multi-core optical fiber as the carrier fully utilizes the dimension of space, can effectively improve the transmission capacity of a single optical fiber and solve the bottleneck problem, and is verified in an ultra-high capacity long-distance optical fiber transmission system and attracts the wide attention of the industry.
With the development of multi-core optical fibers, multi-core optical fibers such as dual-core optical fibers, three-core optical fibers, four-core optical fibers, seven-core optical fibers, nineteen-core optical fibers and the like are gradually applied, and the manufacture of various multi-core optical fiber connecting devices becomes the current practical requirement.
In the process of manufacturing a multi-core optical fiber device, a plurality of single-mode optical fibers or special optical fibers are firstly inserted into a porous quartz capillary according to design parameters of a multi-core optical fiber connecting device, a plurality of capillary holes are generally uniformly distributed in the porous quartz capillary according to a certain geometric shape, and the diameter of each capillary hole is basically close to the outer diameter of the optical fiber, so that when the multi-core optical fiber tail end connecting device is manufactured, the optical fiber is required to be inserted into the capillary without breaking, the optical fiber is required to be efficiently inserted into the capillary, and preparation is made for subsequent device processing and manufacturing.
In the preparation work of inserting the optical fiber into the porous capillary, after the coating layer of the optical fiber is stripped, static electricity is generated on the surface of the optical fiber and carried in the optical fiber in the process of cleaning and wiping the optical fiber, after the optical fiber is inserted into one section of the capillary, the optical fiber is adsorbed on the wall of the capillary due to the static electricity, large friction resistance is generated, the subsequent optical fiber cannot be inserted continuously, an experimenter can usually pull out the inserted optical fiber for secondary insertion, but the optical fiber is broken in the capillary easily in the process of pulling out the optical fiber due to the resistance, so that the consumption of equipment such as the porous capillary, special optical fiber and the like is increased, and the cost is increased.
In the process of inserting the optical fiber into the porous capillary tube, the plurality of optical fibers inserted previously carry static electricity, a larger electrostatic field is generated around the end face of the capillary tube, and as the diameter of the optical fiber is almost equal to that of a hair, when the tail end of the optical fiber is aligned with the capillary hole, the optical fiber cannot keep an alignment angle due to the influence of the electrostatic field of the plurality of optical fibers and is inserted into the capillary hole, the difficulty of aligning the optical fiber with the capillary hole is increased, and the process of inserting the optical fiber into the capillary hole is also influenced.
In the process of inserting the optical fiber into the capillary, the individual optical fiber is influenced by environmental factors and is hardly interfered by electrostatic force, but in the process of inserting the optical fiber into the capillary, the optical fiber is slightly bent under the influence of the gravity of the optical fiber, so that the part of the optical fiber inserted into the capillary is contacted with the inner wall of the capillary, the contact is tighter along with the increase of the insertion length of the optical fiber, the resistance between the optical fiber and the wall of the capillary is larger and larger, and the optical fiber is difficult to be inserted into the porous capillary.
Patent No. CN105842811A discloses a method for threading a long-distance optical fiber into a capillary, which uses magnetic force to drive the optical fiber to be guided into the capillary, but for a porous capillary with a pore size close to the diameter of the optical fiber, the method cannot be used for inserting the optical fiber into the porous capillary.
Aiming at the problem found in the process of inserting the optical fiber into the porous capillary in the manufacturing process of the multi-core optical fiber device at present, the invention designs the device for efficiently inserting the optical fiber into the porous capillary, which starts from the influence factors such as the surface static electricity of the optical fiber, the internal humidity of the capillary or the elimination of the static electricity, the self gravity of the optical fiber and the like, improves the efficiency of inserting the optical fiber into the porous capillary by the modes of eliminating the static electricity, reducing the internal humidity index of the capillary or the static electricity, spirally inserting the optical fiber and the like, reduces the consumption of expensive equipment such as the porous capillary and the like, and further reduces the manufacturing cost of the device.
