Single-mode duplex fiber optic cable is meant to transmit data over long distances with reliability and high speed. Single-mode cables only carry one ray of light at a time, which is what makes them better for long-distance transmissions. A duplex fiber cable consists of two fibers for simultaneous, bi-directional data transfers, earning the nickname of zip cord fiber optic cable systems.
