Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber communication, in particular to an optical fiber communication element. Background Art

[0002] Optical fiber communication is a communication method that uses light waves as carriers and optical fibers as transmission media to transmit information from one place to another. It is called "wired" optical communication.

[0003] Optical fiber communication contains electronic components, which are the basic elements in optical fiber communication technology. They are usually individually packaged and have two or more leads or metal contacts.

[0004] In the prior art, components with more than four pins are all realized by mold top, which has high processing efficiency, but low reliability of mold top packaging, especially hot and cold shock, which will drive the expansion and contraction of the outer sealing colloid, causing the lead to fail due to stress.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] An optical fiber coupling structure, wherein a recess is formed at one end of the optical fiber coupling structure, and a matching optoelectronic transceiver element is disposed inside the recess. The optoelectronic transceiver element adopts a TO full metal package, and the package is filled with nitrogen;

[0009] A rear cover, arranged at a position of the optical fiber coupling structure corresponding to the optoelectronic transceiver element;

[0010] The optical fiber connector is arranged at one end of the optical fiber coupling structure away from the make way groove, and a matching through hole is opened at the end position of the optical fiber connector corresponding to the end of the optical fiber coupling structure away from the make way groove.

Clamping grooves which match with the first clamping jaws are formed at positions corresponding to the first clamping jaws on both side walls of one end of the optical fiber coupling structure close to the rear cover. The rear cover is fixed at one end of the optical fiber coupling structure through the cooperation of the first clamping jaws and the clamping grooves.

[0013] Preferably, a fixing groove is formed at the center position of the upper end face of the optical fiber coupling structure. A fixing position pin which matches with the fixing groove is inserted into the fixing groove. The cross section of the fixing position pin is in a "匚" shape, and two vertical rods of the fixing position pin penetrate through the optical fiber coupling structure through the fixing groove.

[0014] Preferably, the optical fiber connector is inserted into the optical fiber coupling structure through the through hole, and a limiting plate is arranged on the optical fiber connector.

Especially, the leads will not be stressed during thermal shock. Through the cooperation of the optical fiber coupling structure and the rear cover, the optoelectronic transceiver element is installed and fixed inside the optical fiber coupling structure. The opening of the pin slot enables the element pins connected with the optoelectronic transceiver element to extend out from the inside of the optical fiber coupling structure, which is convenient for the connection between the optoelectronic transceiver element and external electrical elements through the element pins.
