A thru-adapter for fiber connectors is a passive device used to connect two fiber optic connectors together in a straight-through configuration without any signal conversion or alteration. Thru-adapters are typically used to extend the length of a fiber optic cable run or to connect two fiber patch cables with the same type of connector.
Thru-adapters have a simple design with two female connector ports on either end that accept the male connectors of the fiber cables. The ports are aligned to allow the fibers to pass through the adapter without any interruption, maintaining a continuous optical connection between the two cables.
Thru-adapters come in various types to accommodate different connector interfaces, such as LC, SC, ST, or MPO. They provide a quick and convenient way to extend fiber optic connections without the need for splicing or terminating new connectors. Thru-adapters are commonly used in data centers, telecommunications networks, and other fiber optic applications where temporary or permanent link extensions are required.
