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.

Fiber Optic Cables Are The First Option For Data Transmission


Fiber Optical Cable has brought a revolution to the data transmission system. As the earlier Electrical Wire System was difficult to manage and was sometimes also hazardous to life. With the emergence of Fiber Optical Cable, data transmission is no more an irksome job. It is now simplified, providing much more convenient than ever imagined.

Following Are The Reasons For Choosing Optical Cables For Network Cabling:

Safe To Use: Fiber Cable is far better than copper cable from the safety point of view. Copper and Aluminum Wire are good conductors of electricity and carry electric current. But when their outer insulated coating gets damaged, one can experience electric shock that can be dangerous to life. In this regard, Fiber Cables are safer to use because they do not transmit current but rather light waves.

Withstand Rough Conditions: Fiber Cable is capable of resisting tough conditions that co-axial or any other such cable cannot do. The reason is that other cables are usually made up of one or the other metal and are prone to corrosion, while Fiber Cable is covered with protective plastic coating with glass inside and transmits light impulses in spite of electric current, which make it resistant towards corrosion.

Long Distance Data Transmission: There cannot be any comparison in terms of data carrying capacity of Fiber Optical Cable and Copper Cable. Fiber Cable can transmit signals 50 times longer than Copper Cable.

Moreover, signal loss rate of Fiber Optical Wire is also very less, and thus does not need any kind of reminder in transmitting the signals at same pace. Fiber Cable has higher bandwidth that is amount of data communication resources available or consumed – this is the reason how Fiber Cable can transmit data at longer distances.

Easy Installation: Ethernet Cable is long and thin with intact cables inside. It is also light in weight which makes its installation at almost every place easier as compared to other wires.

No Electrical Interference: Fiber Optical Cable neither carries electric current nor need earthing. Therefore, it does not get affected by the electrical interferences. Fiber Cable is immune to moisture and lighting, which makes it ideal to be fitted inside the soil or an area where there is high Electromagnetic Interference (EMI).

Durable and Long Lasting: Fiber Optical Cable is durable and lasts longer than any other cable such as Co-Axial Cable, Copper Cable, etc. It is perfect for network cabling.

Data Security: Extra security can be provided with Fiber Optical Cable as it can be tapped easily and data transmitted through it remains secure, while in case of the Copper Cable there is no surety of data security and any loss of data cannot be obtained back.

There are various types of optical fiber cables available on the market, including 250um Bare Fiber, 900um Tight Buffer Fiber, Large Core Glass Fiber, Simplex Fiber Optic Cables, Duplex Multimode Fiber Optic Cable, OM4 OM3 10G Fiber Cable, Indoor Distribution Cable, Indoor & Outdoor Cable, Outdoor Loose Tube Cable, Fiber Breakout Cable, Ribbon Fiber Cable, LSZH Fiber Optic Cable, Armored Fiber Optic Cable, FTTH Fiber Optic Cable, Figure 8 Aerial Cable, Plastic Optical Fiber, Polarization Maintaining Fibers & Special Fiber, etc. They are used for different applications, one must do a thorough research before buying fiber cables for network cabling.

Overview Simplex and duplex Fiber Optic Cable


Simplex and duplex are with various cable structure types; they have some from single mode and multi mode which are related to fiber optic glass types.From FiberStore,we provide some bulk fiber optic cables types in our store.Such as Simplex Fiber Optic Cable and Duplex Fiber Optic Cable,we also have other types cables in it.Customers have the flexibility to choose a cable plant to best fit their needs.We are the professional fiber optic cables supplier ,and provide high quality service for you.

Simplex Fiber Optic Cable:

Simplex Fiber Optic Cables will be used when a signal only needs to go in one direction. They are designed for production termination where consistency and uniformity are vital for fast and efficient operation.

Simplex Fiber Optic Cable consists of a single fiber,tight-buffered (coated with a 900 micron buffer over the primary buffer coating) with Kevlar (aramid fiber) strength members and jacketed for indoor use, and is used mostly for patch cord and backplane applications. 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 Fiber Cable is a single fiber available in single mode, multimode, or polarization maintaining, and they can meet the strength and flexibility required for today’s fiber interconnect applications. We also supply Riser, Plenum rated constructions and LSZH jacket.

Duplex Fiber Optic Cable:

Duplex Fiber Optic Cables consist of two fibers joined by a thin connection between the two jackets. Either single mode or multimode,they are used in applications where data needs to be transferred bi-directionally. One fiber transmits data one direction; the other fiber transmits data in the opposite direction. Larger workstations, switches, servers, and major networking hardware tends to require duplex fiber optic cable.

Duplex fibers types:

  • Half-duplex: Data may only be transmitted in one direction at a time.
  • Full-duplex: Data is transferred in two directions simultaneously.

Other duplex infomation:A duplex communication system is a point-to-point system composed of two connected parties or devices that can communicate with one another in both directions, simultaneously. Now, Duplex systems are employed in many communications networks, either to allow for a communication “two-way street” between two connected parties or to provide a “reverse path” for the monitoring and remote adjustment of equipment in the field.
