ADAPTER ASSEMBLY

An adapter assembly, which relates to the field of optical communication. The adapter assembly comprises: a housing (2), which is enclosed to form a chamber (21); holding sleeves (4) integrally molded with the housing (2), receiving cavities (41) being formed in the holding sleeves (4), wherein one end of each holding sleeve (4) is arranged in the chamber (21) and the other end protrudes from the housing (2), and the holding sleeves (4) have openings (42) which communicate with the receiving cavities (41); clamping members (5) arranged in the openings (42) and detachably connected to the holding sleeves (4); ceramic sleeves (3) arranged in the receiving cavities (41); and fixing members (6) arranged at two ends of the holding sleeves (4) and connected to the holding sleeves (4) so as to limit the ceramic sleeves (3). The axes of the holding sleeves (4) are the axes thereof, which avoids the problem in which a plurality of holding sleeves (4) are not coaxial with each other due to assembly errors, and ensures free floating of the ceramic sleeves (3) in the holding sleeves (4). Therefore, when optical fibers are inserted into two ends of each ceramic sleeve (3) for docking, it is ensured that the optical fibers may be coaxially docked to each other, so that the adapter assembly has good collimation performance.
