Handheld Fiber Optic Coupler and How to Use It

Abstract

The invention belongs to the technical field of machines and discloses a handheld optical fiber coupler and an application method thereof to solve the problems that an existing optical fiber coupler is large in size, heavy and low in using efficiency and consumes time and labor. The optical fiber coupler is composed of a base, a tail fiber table, a tail fiber pressing plate, a coupling body, a fiber guiding hole, a fiber pressing plate and magnets. A shallow groove is formed in the central axis of the tail fiber table. A coupling groove is formed in the central axis of the coupling body. A tail fiber and a measured optical fiber are connected in the coupling groove, the tail fiber pressing plate and the fiber pressing plate are iron pressing plates, and the magnets are arranged at the contact position of the tail fiber pressing plate and the base and the contact position of the fiber pressing plate and the base. The invention further provides the application method of the handheld optical fiber coupler. The optical fiber coupler can be handheld to be operated due to the small size, and is suitable for various construction environments, the labor intensity of constructors is lowered, and the optical fiber coupler can be applied to the field of single-deck testing construction, optical fiber construction fault checking and the like.

Description

technical field [0001] The invention relates to a hand-held optical fiber coupler and a using method thereof, belonging to the technical field of machinery. Background technique [0002] With the continuous development of the national fiber-to-the-home project and overseas optical cable communication projects, the construction links such as single-disc detection, detection within 72 hours after deployment, real-time monitoring of connection, and cable obstacle search in the optical cable line project need to be completed using optical fiber couplers. The fiber core of the tested fiber optic cable is coupled and connected with the fiber core of the test fiber, and then the performance test of the fiber optic cable is completed by using the test instrument. [0003] Compared with single-handed operation, the existing fiber coupler is bulky and heavy, and must be placed on the operating table for operation. The current alignment of the fiber slot is "aimed" by the eyes, resulti...

AI Technical Summary

Problems solved by technology

[0003] Compared with one-handed operation, the existing fiber coupler is bulky and heavy, and must be placed on the operating table for operation. The current alignment of the fiber slot is "aimed" by the eyes, resulting in the "misalignment" of the fiber core and the use efficiency. Low, when using a fusion splicer to splice the fibers, it is time-consuming and laborious, and the slow construction speed leads to an increase in cost

For special scenarios such as corridors and poles in fiber-to-the-home projects or harsh scenarios, construction personnel cannot complete the test work, so they can only give up the test and cannot obtain the required test data, resulting in a decline in project quality
