Asymmetric multimode fiber with directivity and plastic plug

Abstract

The invention discloses an asymmetric multimode fiber with directivity and a plastic plug, which is characterized by comprising a fiber main body, a fiber front plug and a fiber rear plug, wherein the fiber front plug comprises a pin front main body and a pin rear main body, the front main body is a glass core with a diameter of 15 mum to 50 mum, and the rear main body is a tapered glass capillary; the fiber rear plug comprises a plug pin front main body and a plug pin rear main body, the front main body is a tapered glass capillary, the rear main body is a glass core with a diameter of 15 mum to 50 mum, and the front main body and the rear main body are in seamless connection. An integrated mode is adopted for production, the front end of the plastic body is in a shape of a concave cylinder and insertion of the other fiber head is facilitated. When an external fiber is connected with the fiber plug, precise alignment is not needed, the laser signal can be transmitted continuously, and the normal work of the fiber is thus ensured.

Description

【Technical field】 [0001] The invention relates to optical fiber communication equipment, in particular to a directional asymmetrical multimode optical fiber with plastic material plugs. 【Background technique】 [0002] As a high-efficiency and large-capacity transmission medium, optical fiber has been widely used in various fields including communication in recent years to transmit video, voice and data signals. Due to the thin core of the optical fiber, there is a slight deviation between them. It will lead to a large loss of optical signals. Therefore, the effective connection between optical fibers becomes the key to smooth network transmission. [0003] At present, the optical fiber connection, optical transceiver connection, optical fiber plugging and other matters related to optical fiber communication are generally completed by professionals, which are difficult for ordinary users. , which greatly hinders the FTTH fiber-to-the-home project. Therefore, the applicant co...

Problems solved by technology

With existing fiber optic ferrules, it is difficult to precisely control the precision of the ferrules during the manufacturing process, resulting in errors in fiber optic connections.

[0005] The communication optical fiber is very small, like a hair. In order to realize the docking of two optical fibers, the precision requirements for the production of optical fiber ferrules are extremely strict, so that there is no corresponding production technology in China.
