Fiber optic adapters (also called couplers) are designed to connect two fiber optic cables together. They come in versions to connect single fibers together (simplex), two fibers together (duplex), or sometimes four fibers together (quad). Mouser offers inventory, pricing, & datasheets for Multimode Fiber Optic Connectors. Connector types include LC Duplex, SC Simplex, ST and MPO in multimode and singlemode for up to 12 fibers.
