Example

[0032] The first embodiment of the coupler:

[0033] Reference image 3 with Figure 5 , image 3 Is a cross-sectional view of coupler 2, Figure 5 It is a schematic diagram of the structure of the coupler 2. The coupler 2 includes a stainless steel tube 21, silica gel 22, heat shrinkable tube 23, semicircular substrate 241, semicircular substrate 242, epoxy glue 251, epoxy glue 252, optical fiber 261, optical fiber 262, optical fiber 263 and optical fiber 264. The semicircular substrate 241 and the semicircular substrate 242 are made of quartz material, and the semicircular substrate 241 and the semicircular substrate 242 are inverted and matched to form the quartz substrate in this embodiment. The optical fiber 261 and the optical fiber 262 constitute the first optical fiber assembly of this embodiment. The optical fiber 263 and the optical fiber 264 constitute the second optical fiber assembly of this embodiment, and the heat shrinkable tube 23 is used as the fixed tube of thi...

Example

[0040] The second embodiment of the coupler:

[0041] On the basis of the first embodiment of the coupler, in addition to using the heat shrinkable tube 23 as the fixed tube of the first embodiment of the coupler, the fixed tube can also use a quartz tube to fix the semicircular substrates that are inverted with each other. Specifically, a quartz tube sleeve is set, and the length of the quartz tube sleeve is greater than or equal to the quartz substrate. After the quartz tube is sleeved outside the quartz substrate, the dual curing glue is used for heating and ultraviolet light to finally form curing, and then effectively Fixing the optical fiber assembly can achieve this objective of the present invention. The specific use method and principle of dual-curing adhesive can refer to the paper "Double-weight, hardening, chemical, technical, and technical" published by Wang Tao, Master of Anhui University of Science and Technology in 2007, in the U?V? Curing? Adhesive? Adhesive? "C...

Abstract

The invention provides a coupler and a manufacturing method of the coupler. The coupler comprises a quartz substrate, a fixed pipe and a stainless steel pipe, wherein the coupler further comprises two optical fiber assemblies; each optical fiber assembly comprises multiple optical fibers; the multiple optical fibers are melted and tapered; the two optical fiber assemblies are arranged in the quartz substrate; the quartz substrate comprises two semicircular substrates; a through slot is formed in each semicircular substrate along the axial direction; each optical fiber assembly is arranged in each through slot; a space between each through slot and the corresponding optical fiber assembly is filled with epoxy glue; the epoxy glue is positioned on two end parts of the corresponding through slot; each semicircular substrate is provided with end faces extending along the axial direction on two sides of the corresponding through slot; the two semicircular substrates are inversely buckled and matched; the end faces of the two semicircular substrates are adjacent. The invention also discloses the method for manufacturing the coupler. The two optical fiber assemblies are integrated in the same coupler in a high integration manner, and the usability of the space in the coupler is effectively increased.

Description

technical field [0001] The invention relates to the field of optical fiber communication, in particular to a coupler and a manufacturing method of the coupler. Background technique [0002] Optical fiber coupler, also known as splitter, connector or adapter, is a component used to realize optical signal splitting or combining, or to extend optical fiber links. It belongs to the field of optical passive components and is used in telecommunication networks and cable television networks. , user loop system, and local area network will be applied. Optical fiber coupler is a kind of important passive device, and single-mode optical fiber coupler is a kind of passive device that is widely used in optical fiber communication system, optical fiber sensor, optical fiber measurement technology and signal processing system. [0003] At present, the fusion tapered method (FBT) is commonly used at home and abroad to make fiber optic couplers. The fusion tapered method is to bring two or...
