Duplex Fiber Cables consist of two fibers joined by a thin connection between the two jackets. Workstations, fiber switches and servers, optical fiber modems, and similar hardware require duplex fiber. They are used in applications where data needs to be transferred bi-directionally. One fiber transmits data one direction; the other fiber transmits data in the opposite direction. Duplex fiber cable from Fiberinthebox can be available in single mode duplex fiber and multimode duplex optical fiber cable.
