FacebookTwitterGoogle+LinkedInRedditTumblrShare

Fiber optic patch cable is available in OM1, OM2, OM3, OM4 multimode and OS2 single-mode types. Both ends of the cable are terminated with a high performance hybrid or single type connector comprising of a SC, ST, FC, LC, MTRJ, E2000 connector in simplex and duplex. These are typically not ruggedized, depending on the application, making them suitable for internal use. How to choose right patch cables for your network? Just follow these 6 steps.

Step 1: Choose the Right Connector Type (LC/SC/ST/FC/MPO/MTP)

Different connector is used to plug into different device. If ports in the both ends devices are the same, we can use such as LC-LC/SC-SC/MPO-MPO patch cables. If you want to connect different ports type devices, LC-SC/LC-ST/LC-FC patch cables may suit you.

Step 2: Choose Single-mode or Multimode Cable Type?
Single-mode fiber patch cord uses 9/125um glass fiber, Multimode fiber patch cord uses 50/125um or 62.5/125um glass fiber. Single-mode fiber optic patch cable is used in long distance data transmission. multimode fiber optic patch cable is use in short distance transmission. Typical single-mode fiber optic patch cable used yellow fiber cable and multi mode fiber optic patch cable used orange or aqua fiber cable.

Step 3: Choose Simplex or Duplex Cable Type?
Simplex means this fiber optic patch cable is with one cord, at each end is only one fiber connector, which is used for Bidirectional (BIDI) fiber optic transceivers. Duplex can be regarded as two fiber optic patch cable put side by side, which is used for common transceivers.

Step 4: Choose the Right Cable Length (1m/5m/10m/20m/30m/50m)
Fiber optic patch cables are made in different lengths, usually from 0.5m to 50m. You should choose an appropriate cable length according to the distance between the devices you want to connect.

Step 5: Choose the Right Connector Polish Type (UPC/APC)
Since the loss of the APC connector is lower than UPC connectors, usually, the optical performance of APC connectors is better than UPC connectors. In the current market, the APC connectors are widely used in applications such as FTTx, passive optical network (PON) and wavelength-division multiplexing (WDM) that are more sensitive to return loss. But APC connector is usually expensive than UPC connector, so you should weigh the pros and cons. With those applications that call for high precision optical fiber signaling, APC should be the first consideration, but less sensitive digital systems will perform equally well using UPC. Usually, connector color of APC patch cable is green, and of UPC patch cable is blue.

Step6: Choose the Right Cable Jacket (PVC/LSZH/OFNP/Armored)
Usually, there are three cable jacket types: Polyvinyl Chloride (PVC), Low Smoke Zero Halogen (LSZH) and Optical Fiber Nonconductive Plenum (OFNP). You can see there features in figure below and choose the right one for your network.

Besides the three cables mentioned above, there is another common cable—Armored Cable. The double tubing and steel sleeve construction make these patch cables completely light tight, even when bent. These cables can withstand high crushing pressures, making them suitable for running along floors and other areas where they may be stepped on. The tubing also provides excellent cutting resistance, abrasion resistance, and high tensile strength.

WDM Optical MUX Technology

With the exponential growth in communications, caused largely by the wide acceptance of the Internet, many carriers have found their estimates of fiber needs have been highly underestimated. Although most cables included many spare fibers when installed, this growth has used many of them and new capacity is required. Make use of a number of ways to improve this problem, eventually the WDM has shown more cost effective in most cases.

WDM Definition:

Wave Division Multiplexing (WDM) enables multiple data streams of varying wavelengths (“colors”) to become combined right into a single fiber, significantly enhancing the overall capacity from the fiber. WDM can be used in applications where considerable amounts of traffic are needed over long distance in carrier networks. There’s two types of WDM architectures: Course Wave Division Multiplexing (CWDM) and Dense Wave Division Multiplexing (DWDM).

WDM System Development History:

A WDM system uses a multiplexer in the transmitter to become listed on the signals together, and a demultiplexer at the receiver to separate them apart. With the right type of fiber it is possible to have a device that does both simultaneously, and can work as an optical add-drop multiplexer. The optical filtering devices used have conventionally been etalons (stable solid-state single-frequency Fabry¡§CP¡§|rot interferometers by means of thin-film-coated optical glass).

The idea was first published in 1980, and by 1978 WDM systems appeared to be realized in the laboratory. The first WDM systems combined 3 signals. Modern systems are designed for as much as 160 signals and can thus expand a fundamental 10 Gbit/s system over a single fiber pair to in excess of 1.6 Tbit/s.

WDM systems are well-liked by telecommunications companies because they allow them to expand the capacity of the network without laying more fiber. By utilizing WDM and optical amplifiers, they can accommodate several generations of technology rise in their optical infrastructure without needing to overhaul the backbone network. Capacity of a given link can be expanded by simply upgrades towards the multiplexers and demultiplexers at each end.

This is often made by use of optical-to-electrical-to-optical (O/E/O) translation in the very edge of the transport network, thus permitting interoperation with existing equipment with optical interfaces.

WDM System Technology:

Most WDM systems operate on single-mode fiber optical cables, which have a core diameter of 9 µm. Certain forms of WDM may also be used in multi-mode fiber cables (also referred to as premises cables) which have core diameters of fifty or 62.5 µm.

Early WDM systems were expensive and complicated to operate. However, recent standardization and better understanding of the dynamics of WDM systems make WDM less expensive to deploy.

Optical receivers, as opposed to laser sources, tend to be wideband devices. Therefore the demultiplexer must provide the wavelength selectivity of the receiver in the WDM system.

WDM systems are split into different wavelength patterns, conventional/coarse (CWDM) and dense (DWDM). Conventional WDM systems provide up to 8 channels within the 3rd transmission window (C-Band) of silica fibers around 1550 nm. Dense wavelength division multiplexing (DWDM) uses the same transmission window but with denser channel spacing. Channel plans vary, but a typical system would use 40 channels at 100 GHz spacing or 80 channels with 50 GHz spacing. Some technologies are capable of 12.5 GHz spacing (sometimes called ultra dense WDM). Such spacings are today only achieved by free-space optics technology. New amplification options (Raman amplification) enable the extension of the usable wavelengths towards the L-band, pretty much doubling these numbers.

Coarse wavelength division multiplexing (CWDM) in contrast to conventional WDM and DWDM uses increased channel spacing to allow less sophisticated and thus cheaper transceiver designs. To supply 8 channels on one fiber CWDM uses the whole frequency band between second and third transmission window (1310/1550 nm respectively) including both windows (minimum dispersion window and minimum attenuation window) but the critical area where OH scattering may occur, recommending using OH-free silica fibers in case the wavelengths between second and third transmission window ought to be used. Avoiding this region, the channels 47, 49, 51, 53, 55, 57, 59, 61 remain and these are the most commonly used.Each WDM Optical MUX includes its optical insertion loss and isolation measures of every branch. WDMs are available in several fiber sizes and kinds (250µm fiber, loose tube, 900µm buffer, Ø 3mm cable,simplex fiber optic cable or duplex fiber cable).

WDM, DWDM and CWDM are based on the same idea of using multiple wavelengths of sunshine on one fiber, but differ within the spacing of the wavelengths, quantity of channels, and also the capability to amplify the multiplexed signals within the optical space. EDFA provide an efficient wideband amplification for that C-band, Raman amplification adds a mechanism for amplification in the L-band. For CWDM wideband optical amplification is not available, limiting the optical spans to many tens of kilometres.

Regardless if you are WDM Optical MUX expert or it is your first experience with optical networking technologies, FiberStore products and services are equipped for simplicity of use and operation across all applications. If you want to choose some fiber optic cable to connect the WDM, you are able to make reference to our fiber optic cable specifications.Have any questions, pls contact us.

Duplex Fiber Among Fiber Optic Cables

Duplex Fiber Cable

Duplex fiber cable is designed for general fiber patch cord production where consistency and uniformity are vital for fast, efficient terminations. We have the right duplex fiber cable in many different outside diameter (OD) sizes and meet all tooling and termination requirements.Duplex Fiber Optic Cables consist of two fibers joined by a thin connection between the two jackets. Workstations, fiber switches and servers, fiber optic modems, and similar hardware require duplex cable. 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. Duplex fiber optic cables from FiberStore can be available in single-mode and multimode.

Multimode vs Singlemode Fiber

A “mode” in Fiber Optic cable refers to the path in which light travels. Multimode cables have a larger core diameter than that of singlemode cables. This larger core diameter allows multiple pathways and several wavelengths of light to be transmitted. Singlemode Duplex cables and Singlemode Simplex cables have a smaller core diameter and only allow a single wavelength and pathway for light to travel. Multimode fiber is commonly used in patch cable applications such as fiber to the desktop or patch panel to equipment. Multimode fiber is available in two sizes, 50 micron and 62.5 micron. Singlemode fiber is typically used in network connections over long lengths and is available in a core diameter of 9 microns (8.3 microns to be exact). Many types of multimode fiber optic cable (such as om3 multimode fiber) and singlemode fiber optic cable for sale in FiberStore.

How Fiber Optic Cables Work

The traditional method of data transmission over copper cables is accomplished by transmitting electrons over a copper conductor. Fiber Optic cables transmit a digital signal via pulses of light through a very thin strand of glass. Fiber strands (the core of the fiber optic cable) are extremely thin, no thicker than a human hair. The core is surrounded by a cladding which reflects the light back into the core and eliminates light from escaping the cable.

A fiber optic chain works in the following manner. At the one end, the fiber cable is connected to a transmitter. The transmitter converts electronic pulses into light pulses and sends the optical signal through the fiber cable. At the other end, the fiber cable is plugged into a receiver which decodes the optical signal back into digital pulses.

Advantages & Disadvantages of Fiber Optic Cable

There are many advantages and disadvantages in using fiber optic cable instead of copper cable. One advantage is that fiber cables support longer cable runs than copper. In addition, data is transmitted at greater speeds and higher bandwidths than over copper cables.
The major disadvantages of fiber optic cables are cost and durability. Fiber cables are more expensive than copper cables and much more delicate.

Three Steps To Pick Out A Fiber Optic Cable
So when you go to pick out a fiber optic cable, there are a few things you’ll want to know. First, make sure that the type of connector you purchase matches your input connection. Second, check to see if your device prefers single or multi-mode transfer. Figure out if you need simplex fiber optic cable or duplex fiber optic cable. And finally, choose which length you need. You can discern this by setting up your system and running a string from the speaker or TV to the equipment. Always buy the next larger length rather than one that is on the small side. You won’t regret it!

Relationship Between The Fiber Optics And Fiber Optic Cable

Fiber Optic Cable:

In fiber optic cable, optical fibers carry digital data signals in the form of modulated pulses of light. This is a relatively safe way to send data because no electrical impulses are carried over the fiber optic cable. This means that fiber-optic cable cannot be tapped and the data stolen, which is possible with any copper-based cable carrying data in the form of electronic signals.

Fiber optic cable is good for very high-speed, high-capacity data transmission because of the lack of attenuation and the purity of the signal.

A fiber optic cable can transmit information at very high speed over a very great distance. It comprises one or more optical fibers enveloped in a thermoplastic sheath for mechanical protection.

Fiber Optic Composition:

Optical fibers consist of an extremely thin cylinder of glass, called the core, surrounded by a concentric layer of glass, known as the cladding. The fibers are sometimes made of plastic. Plastic is easier to install, but cannot carry the light pulses as far as glass.

Each glass strand passes signals in only one direction. So a cable consists of two strands in separate jackets. One strand transmits and one receives. A reinforcing layer of plastic surrounds each glass strand while kevlar fibers provide strength.

Fiber Optic Technologies

Data transmission via fiber optic cable uses a laser beam, offering very little loss over great distances. The core fiber has a higher refractive index than its cladding material, keeping the light within by avoiding multiple reflection (single-mode fiber), thus acting as a wave guide.

Fiber Optic Cable Types:

Now,many fiber optic cable suppliers provide a wide range of quality optical fiber cables with detailed fiber optic cable specifications displayed for your convenience selecting.Many types of fiber optic cable including about 250um bare fiber,tight buffer,large core glass,simplex fiber optic cable,duplex fiber cable,OM3 OM4, Indoor Outdoor cable,loose tube,breakout cable,ribbon cable,LSZH cable,armored cable,ftth cable,figure 8 aerial cable,plastic cable,hybrid and composite cable,adss cable,special cable and so on.

How to Choose Fiber Optic Cable?

Fiber optic cables are preferable to electrical cables over long transmission distances or when an electromagnetic disturbance in an industrial setting might interfere with the signal. Single-mode fibers are required for high-speed, long-distance transmission, while multi-mode fibers are suitable for low speeds and short distances.

Optical fibers have found a widespread use in optical technologies. Today is electronical high-tech applications as for example the Laser Scanning Microscopy, the sensor technology, machine vision, medical laser or military technology use flexible elements in form of optical fibers for light transfer frequently. In most cases, very special requirements to design and function of optical fiber cables are put. We realize custom-made solutions regarding the design of fiber connectors and wavelength, transceiver sale mode behavior, polarization and beam profile.This enables short decisions and high flexibility in the creation of single components as well as system solutions. FiberStore wide-ranging competence is a substantial advantage in the realization of custom solutions. Want to know more customized to fiber optic products(such as 10g fiber cable).

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.
