Fiber optic adapters are passive components of fiber-optic communication lines intended for high-precision centering and connecting optical cables with all types of connectors. They ensure reliable contact, do not allow axial misalignment, and guarantee the stability of the network parameters. They are used in active equipment and in optical fiber distribution frames and are attached using threaded connections or stoppers. There are two types: feed-through and transformable optical adapters. The former are used for connectors of the same type, the latter have different types of connectors on each side.

XI'AN OPT offers a wide range of Male-Female and Female-Female fiber adapter couplers for connecting single-mode (SM) and multi-mode (MM) simplex/duplex cords, including those with APC or UPC polishing.
