Details

Simplex Fiber Cable
A simplex fiber cable consists of a single strand of glass of plastic fiber. Simplex fiber is most often used where only a single transmit and/or receive line is required between devices or when a multiplex data signal is used (bi-directional communication over a single fiber).

Duplex Fiber Cable
A duplex fiber cable consists of two strands of glass or plastic fiber. Typically found in a “zipcord” construction format, this cable is most often used for duplex communication between devices where a separate transmit and receive are required.

Multi-Fiber Fiber Cable (6 cores, 12 cores, or more fiber counts)
A Multi-Fiber Fiber Cable fiber cable consists of many strands of glass or plastic fiber. Typically found in a 6 cores, 12 cores, or more fiber counts indoor or outdoor fiber cable with strength jacket,

FAQ

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.

Simplex VS. Duplex Fiber Optic Cables
As mentioned above, a simplex fiber optic cable has only one tight-buffered fiber inside cable jacket. The protective jacket enables the cable to be connected and crimped to a mechanical connector. However, duplex fiber optic patch cord can be regarded as two simplex cables having their jackets conjoined by a strip of jacket material, some duplex fiber optic jumper cables are with clips on the two fiber optic connectors at each side of the cable to combine the two connectors together. For the sake of using less source material, simplex fiber optic cable is cheaper than duplex optical cable. Furthermore, simplex optical fiber cable uses only single one strand of fiber in one-way transmission mode, while duplex fiber cable uses a pair of fiber in bi-directional transmission mode.

How to Choose Simplex and Duplex Fiber Optic Cables?
Single mode and multimode simplex optic patch cords can be used for applications that only require one-way data transfer. They are usually used to accomplish connectivity between two BiDi transceivers, which is usually designed with LC simplex single mode fiber to fit the optical interface of the BiDi SFP/ SFP+ optics and operating wavelength. In addition, simplex BiDi WDM Mux/DeMux is designed for use in single strand fiber transmission. So it also needs the simplex fiber cable to combine and separate wavelengths. In addition to these equipments, there are so many other components associated with simplex fiber solution, such as simplex PLC (Planar Lightwave Circuit) splitters, OADM (Optical Add Drop Multiplexer) and other simplex fiber products. As for duplex fiber optic cables, they are usually used in standard optical transceivers, such as SFP, 10G SFP+, 40G QSFP+ and 100G QSFP 28 (only LC duplex fiber cables can be used for long distance, such as 40G-LR4 and 100G-LR4). When the distance between two device is too long, duplex fiber is also used for interconnector or cross connector between fiber optic transceivers and MPO/MTP cassettes.
