The zipcord cable is made by evenly applying strands of Aramid yarns as the strength member over ф900μm or ф600μm tight buffer fibers and then is completed with PVC(LSZH)jacket. A duplex fiber optic cable consists of two strand fibers of glass or plastic, and it can be regarded as two simplex cables. This duplex zipcord cable is carefully structured in a zip-cord arrangement, which is most often used for duplex communication between devices where require simultaneous, bi-directional data transfer. (One fiber transmits data one direction and another fiber transmits data in the opposite direction.) Larger workstations, fiber switches and servers, fiber modems, and similar hardware tends to require duplex fiber cable. Duplex fiber is also available in single mode duplex fiber optic cable and multimode duplex fiber optic cable. Half duplex and full duplex are two types of fiber optic duplex cables that are used in different data transmission applications.
