Abstract

The invention relates to the technical field of optical communication and provides an optical fiber adapter structure. It includes a metal flange 101, a tube body 102, an insulating ring 103, and an optical fiber ferrule 104. The structure also includes a shielding ring 108, the optical fiber ferrule 104 is embedded in the metal flange 101, and the shielding ring 108 is conductive The glue 107 is fixed on the bottom of the metal flange 101; wherein, the shielding ring 108 covers the end of the pin 104, and reserves a hole only for the laser signal to pass through; the tube body 102 is sleeved on the The bottom of the metal flange 101 , and the insulation between the pipe body 102 and the metal flange 101 is realized by the insulating ring 103 . In the present invention, the conductive adhesive 107 bonds the shielding ring 108 made of conductive material to the end of the metal flange 101 and maintains complete electrical contact, reducing electromagnetic wave radiation between the inside of the optical device and the outside of the metal flange 101 .

Description

【Technical field】 [0001] The invention relates to the technical field of optical communication, in particular to an optical fiber adapter structure. 【Background technique】 [0002] Optical fiber communication systems are developing towards high speed and high port density. As one of the core components of optical fiber communication, optical devices are also facing these technical challenges. The more compact etc. [0003] At present, the frequency of signals processed by high-speed optical devices has reached 25 GHz, and the electromagnetic compatibility problems caused by high-frequency signals are very serious. In order to improve the influence of electromagnetic compatibility problems, optical fiber communication systems, high-speed optical modules, and optical devices usually use metal materials as housings, and at the same time minimize the gaps between housing components. Partially strengthen electromagnetic shielding and other means, and at the same time reduce the...
