Larger workstations, switches, servers, and major networking hardware tends to require duplex fiber optic cable. Simplex vs Duplex Fiber Optic Cables. Simplex and duplex are with various cable structure types; they are different from single mode and multi mode which are related to fiber optic glass types.
Simplex and half-duplex systems use only one fiber to communicate, therefore, they are less expensive to build. When purchasing a fiber optic cable, it is important to understand the different varieties of core characteristics that are available within the cable itself.
Each of these different characteristics will have different effects on your ability to transmit information reliably, and these different characteristics also affect the cabling project. You must search the cost of fiber optic cable if you bought the cable. Simplex Fiber Cable A simplex fiber cable consists of a single strand of glass of plastic fiber, and is used for applications that only require one-way data transfer.
Simplex fiber is most often used where only a single transmit and receive line is required between devices or when a multiplex data signal is used bi-directional communication over a single fiber. Simplex fiber is available in singlemode and multimode. For example, an interstate trucking scale that sends the weight of the truck to a monitoring station or an oil line monitor that sends data about oil flow to a central location.
Duplex Fiber Cable A duplex fiber cable consists of two strand fibers of glass or plastic. Use multimode duplex fiber optic cable or single mode duplex fiber for applications that require simultaneous, bi-directional data transfer. Workstations, fiber switches and servers, fiber modems, and similar hardware require duplex fiber cable. So pull strength is not too important. But other cable may be pulled through 2 km or more of conduit. Even with lots of cable lubricant, pulling tension can be high.
Simplex and duplex jumpers can also be called single and double single core, dual core. Simplex is that data transmission only supports transmission in one direction. The two ends of communication, one end is the transmitter and the other end is the receiver, which is not reversible. For example, broadcast stations usually only send signals to viewers, and do not receive signals from viewers. Duplex is divided into half duplex and full duplex.
Half-duplex can transmit data in both directions on the signal carrier, but not at the same time. It can also be said that the half-duplex mode is a simplex communication with switchable directions. For example, on walkie-talkie, when you press the call button, you can send a conversation to the other party, and the other party can hear it, but the other party cannot talk to you at the same time.
This makes it similar to a two-way radio. In addition, full duplex is two-way communication achieved over a physical link that has the ability to communicate in both directions simultaneously. A simplex fiber optic cable consists of one single strand of glass of plastic fiber and one single outer jacket. Simplex fiber is most often used for applications that only require one-way data transfer.
Digital data readouts, interstate highway sensor relays, and automated speed and boundary sensors for sports application are all great uses of simplex fiber optic cable.
In simplex fiber optic network, there are available in simplex single mode and simplex multimode fiber optic cable eg: Single mode simplex fiber patch cable is a great option for setting up a cable network that will require data to travel in one direction over long distances. The simplex multimode fiber has a larger diameter core that effectively allows multiple modes of light to propagate. The number of light reflection is created due to a larger diameter.
The core of a single mode simplex optic patch cord is 8 to 10 microns, while a multimode simplex optic patch cord is either 50 or More data passes through the multimode fiber at a given point in time.
The quality of the signal is reduced over long distances due to high dispersion and attenuation rate with this type of fiber. Multimode fiber is used for short distance data transmission purposes. 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.
