Abstract: An optical fiber adapter, relating to field of optical communication and comprising: a housing with a chamber having a first and second chamber connected with each other and respectively with two opposite ends of the housing; a retaining member integrally formed with the housing and provided within the first chamber, which is enclosed to form an receiving cavity having a first and second openings at one and other ends, respectively, and a third opening extending along a length direction of the retaining member; a retaining cover plate for detachably connecting to the retaining member to seal the third opening; and a ceramic sleeve provided within the receiving cavity and adjacent to the retaining cover plate, which has a third chamber connected with the first and second opening, and is limited within the receiving cavity. The retaining member is an integrated structure, improving the collimation performance of the adapter.

Abstract: An adapter assembly, relating to field of optical communication and comprising: a housing enclosed to form a chamber; a holding sleeve integrally formed with the housing, in which a receiving chamber is provided, wherein one end of the holding sleeve is provided in the chamber and the other end protrudes from the housing, and wherein the holding sleeve is provided with an opening communicated with the receiving chamber; a clamping member provided in the opening and detachably connected with the holding sleeve; a ceramic sleeve provided within the receiving chamber; and fixing members provided at two ends of the holding sleeve and fixedly connected with the holding sleeve to limit the ceramic sleeve. The axes of holding sleeves are the axes thereof, which avoids multiple holding sleeves from deviating each other due to assembly errors, and ensures that the ceramic sleeve may float freely within the holding sleeve.

Abstract: Disclosed is a gravity-adapted optical-fiber-connector comprising a gravity-adapted block and at least one gravity connector each including a fiber-stub; tail handle; rear seat being clamped and fixed by gravity-adapted block; elastic device being sleeved on a portion of excircle surface of tail handle and limited by an end face of rear seat and that of tail handle; outer sleeve and optical cable; gravity of gravity-adapted block is applied to elastic device through the end face of rear seat, after the elastic device is compressed, a spring having identical magnitude and direction with the gravity is generated and acted on the end face of tail handle, such that a physical butt-joint-surface of fiber-stub is always applied a preload about the gravity. The gravity-adapted optical-fiber-connector has stable optical-fiber coupling efficiency and coupling performance.
