Duplex Fiber Optic Cables

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 fiber 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.

Duplex Fiber Optic Cable

Half Duplex Fiber Optic Cables

Half duplex fiber optic cable is capable of sending the signal in both directions but in only one direction at a time. Some transmission network uses half duplex cables but it is necessary to specify this requirement for all the nodes in the network. For instance, half duplex fiber optic can be used in police car radio phones to allow only one person to talk at each time.

Full Duplex Fiber Optic Cables

In the full duplex fiber optic cables, the data is transferred in two different directions simultaneously on a single carrier at the same time. An example is a telephone IP service where people at both ends of a call can speak and be heard by each other at the same time because there are two communication paths between them, thus using the full duplex mode can increase the efficiency of communication.
