The FO-7 is a low-cost duplex fiber optic connector originally developed for consumer electronics. It has been used in some factory automation applications because it was one of the few low-cost connectors available at the time.

Industrial Fiber Optics manufactures multiple product lines of premium quality fiber optic patch cords suitable for industrial networking and other applications. The product lines below are made with OFS fiber cable 200/230 µm glass-core fiber and terminated with FO-7 fiber optic connectors. FO-7 connections are OFS crimp and cleave, eliminating the fiber core "pistoning" problem common with this type of fiber and other connectors. For maximum retention strength, epoxy is used to bond the core/cladding and jacket to the connector. These standard patch cords are available either from stock or quickly made to order. Measured insertion loss data for each cable can be provided upon special request, as well as custom cable lengths.
