Abstract

The invention discloses an optical fiber adapter with high sealing performance. The invention aims to solve the problems that when an encapsulation type adapter is used in an extreme environment for a long time, the stability of sealing performance is difficult to guarantee because a colloid material can age in the extreme environment and even has the possibility of non-uniform distribution in the aging process, and a few products adopting optical fiber metallization sealing are large in size and poor in three-proofing performance. The optical fiber adapter of the invention mainly comprises a shell, a mounting plate assembly and a disc sealing assembly. According to the optical fiber adapter, through an integrated part and welding process treatment, an existing potting treatment sealing mode is replaced; compared with a glue potting bonding mode, the optical fiber adapter has better environment resistance; compared with a metallization sealing optical fiberproduct, the optical fiber adapter is small in volume and good in three-proofing performance; and reliable transmission of multiple paths of optical signals can be realized while the requirement for high air-tight sealing performance is met.

Description

technical field [0001] The invention belongs to the technical field of optical fiber communication, and in particular provides an optical fiber adapter with high sealing performance. Background technique [0002] In order to be able to use a highly reliable and highly integrated optical integrated interconnection system on the wall-penetrating device in the airborne system, it is necessary to provide an optical fiber adapter with a hermetic sealing function. Existing airtight optical fiber adapters often use glue potting and bonding to realize the airtight function. When the potted adapter is used in an extreme environment for a long time, the colloidal material will age in the extreme environment, and there may even be uneven distribution of the aging process, making it difficult to ensure the stability of the airtight performance. A small number of products that use optical fiber metallization and sealing are bulky and poor in three-proof performance. Contents of the in...
