Simplex Fiber Optic Cables
Simplex means this cable is with only one thread of fiber optic glass inside the single core. Additionally, simplex cables are with one single outer jacket. Simplex fiber optic cable is used in applications that only require one-way data transfer. For instance, 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. There are singlemode and simplex multimode fiber optic cable available. Single-mode simplex fiber optic cable is a great option for anyone setting up a cable network that will require data to travel in one direction over long distances. Since this type of cable only carries one ray of light at a time, it’s better for long-distance transmissions. Single-mode fiber is very reliable that it has a high-carrying capacity as well as lower power consumption than other options.
Analog to digital data readouts, interstate highway sensor relays, and automated speed and boundary sensors (for sports applications) are all great uses of Simplex fiber optic cable. This form of fiber cable can be cheaper than Duplex cables, because less material is involved. Simplex cable is compatible with any HDMI extender.
Duplex Fiber Optic Cables
Duplex fiber cable can be regarded as two simplex cables, either single mode or multimode, having their jackets conjoined by a strip of jacket material, usually in a zipcord (side-by-side) style. Use duplex multimode or singlemode fiber optic cable for applications that require simultaneous, bi-directional data transfer(One fiber transmits data one direction; the other fiber transmits data in the opposite direction). Duplex fiber is available in singlemode and multimode.
Duplex multimode fiber optic cable and Singlemode duplex cable alike are used for two-way data transfers. Larger workstations, switches, servers, and major networking hardware tends to require duplex fiber optic cable. Duplex cables can be more expensive than Simplex cables, and are compatible with any HDMI extender.
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.
Some Tips To Choice Simplex And Duplex Fiber Cable
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. Now, let’s take a look at the most common fiber optic cables.
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. Typically found in a “zipcord”(side-by-side) construction format, this cable is most often used for duplex communication between devices where a separate transmit and receive are required. Duplex fiber is available in singlemode and multimode. 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.
Cable Design Criteria For The Pulling Strength,Water Protection,Fiber Code Ratings
Pulling Strength: Some cable is simply laid into cable trays or ditches. 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. Most cables get their strength from an agamid fiber, a unique polymer fiber that is very strong but does not stretch – so pulling on it will not stress the other components in the cable. The simplest simplex cable has a pull strength of 100-200 pounds, while outside plant cable may have a specification of over 800 pounds.
Water Protection: Outdoors, every cable must be protected from water or moisture. It starts with a moisture resistant jacket, usually PE (polyethylene), and a filling of water-blocking material. The usual way is to flood the cable with a water-blocking gel. It’s effective but messy – requiring a gel remover. A newer alternative is dry water blocking using a miracle powder – the stuff developed to absorb moisture in disposable diapers. Check with your cable supplier to see if they offer it.
Fire Code Ratings: Every cable installed indoors must meet fire codes. That means the jacket must be rated for fire resistance, with ratings for general use, riser (a vertical cable feeds flames more than horizontal) and plenum (for installation in air-handling areas. Most indoor cables use PVC (polyvinyl chloride) jacketing for fire retardance. In the United States, all premises cables must carry identification and flammability ratings per the NEC (National Electrical Code) paragraph 770.
