POF Production Has Made Great Breakthrough But Problems Exist In The Marketing

In the construction of modern communication networks, fiber optic cables have been at a dominant position in recent years, such as the FTTH cable. These cables commonly use quartz fiber as the raw material.

Currently, the plastic optical fiber (POF) is increasingly being perceived by people, and the bulk manufacture of this product has made great breakthrough. However, because the market is still at a low level of awareness, business promotion is still too difficult.

So far, the cables that used in fiber optic communication are basically using quartz fiber by adding an appropriate amount of dopant composition to high purity silicon dioxide. In recent years, the plastic optical fiber is also developed gradually. It is an optical fiber made of a light-transmissive polymer. By using a mature and simple drawing technology of the polymer, the POF has a relatively low cost, and is relatively soft, strong, with large diameter (approximately 1mm) and low splice loss.

Plastic fiber optic cable is a light guide medium for transmitting optical signals. It consists of a single or multi-core plastic optical fiber coated by outer PE, PVC and other plastic sheath. POF cables are used in high-speed data transmission, broadband access, FTTH, FTTD, intelligent home and office networking, automotive multimedia, industrial control, factory automation, automotive and aircraft as well as military applications. They are also used in a variety of short-distance data communications including audio jumpers, sensors, ground and short circuit protection, and other plastic indication fiber optic networks, local area networks, home and office optical network, enterprise optical network, digital surveillance, IPTV broadband connection, plastic optical fiber sensors.

The technology of POF’s mass production has made great breakthrough, the plastic optical fiber industry has broad prospects in marketing. Currently, telecommunications companies in Europe and North America and the European POF Union have been testing plastic optical fiber. They believe that this medium has advantages including easy to install, low-cost, flexible, no damage to the naked eye, etc.. They want to slather POF cable into the home and business. In China, the high-tech industry plastic optical fiber has both challenges and opportunities. For its location, losses, costs and chain support, there are still doubts in the industry, and its market awareness is not high enough.

The low market awareness causes that, though plastic optical fiber technology has made great breakthrough, there are problems existing in the promotion of commercial applications.

Merits and Applications of Fiber Optic Cables

Merits and Applications of Fiber Optic Cables

Fiber optic cable consists of glass fibers, allowing for significantly higher transfer speeds compared to copper. The cable uses glass fibers instead of copper wires to transmit conversation and data. Glass cables need to be custom-cut so that they have a nice crisp edge that doesn’t scatter the light, but plastic optical fiber can be trimmed on the jobsite.

From a technical standpoint, fiber optic cable consists of a bundle of glass or plastic rods that can transmit data signals. Fiber optic cable can send and receive in both analog and digital formats, and can carry video, voice, and internet packets. Some new cable designers will actually provide built-in bend limits to protect the glass within. The light beam bounces off the side of the glass or plastic fibers in the cable, which are thinner than a human hair. The light does not pass through the wall of the fiber, but is reflected back in and travels along to the end of the fiber.

The fiber optic cables have clear advantages over the copper cables. There is more security, and the fiber optic cables are more reliable than any other wire available. However, they have some disadvantages too. While copper wires can be spliced and mended as many times as needed, it is much harder to fix glass fiber optic cables. And this time it’s not all dependent on one market. Theoretical work showing that light loss in glass fibers could be decreased dramatically spurred experimental efforts to produce such fibers. Researchers continued exploring techniques to decrease light loss in optical fibers. Fiber-optic cables are not crimped, soldered, or twisted together when they are repaired. If the cable is broken, another cable must be cut to fit between the two connectors.

Whatever, fiber optic cable is a wonderful thing. It can transmit almost insane amounts of data per second , and it is completely impervious to surges, magnetic fields , lightning , and all the other EM nasties that can affect copper cable. Fiber optic data transmission uses light in glass fiber cable as a communication medium. It is ideal for spanning areas with severe interference, such as near heavy electrical equipment, welding or radio transmissions.

Fiber optic cable is the main choice for high speed Internet connections and the primary material used for country to country or continent to continent Internet connections. Fiber optic cable can be installed easily from point to point, passing right next to major sources of EMI with no effect. Conversion from copper networks is easy with media converters, gadgets that convert most types of systems to fiber optics. Fiber optic cable is now being used to transport both video and audio signals for short and long distances. It carries multiple services throughout campus including: voice, video, cable TV, and data. In addition to having the fiber cable in place, newer fiber cable TV distribution equipment became more readily available at a reduced cost. The fiber optic cable and lens allows the instrument electronics to be kept away from the target environment where it would be subjected to higher temperatures, smoke, dust, steam or powerful electromagnetic emissions such as generated by induction heating. Both the stainless steel lens and rugged cable assembly can be replaced in the field without returning the instrument for calibration.

Because of the wide range applications of fiber optic cables, Network operators are looking to recoup the cost of the fiber optic cable and other infrastructure pieces that make a high-speed Internet possible. They argue that the upgrades are necessary to deliver such innovations as high-definition video-on-demand and high-quality teleconferencing. Fiberstore fiber optic cables provide superior tensile strength and resistance to cut-through and abrasion while maintaining flexibility. Whether common fiber cables or POF cable, figure of 8 cable and other special cables are right for sale with best price.

Advantages of Plastic Optical Fibers

Advantages of Plastic Optical Fibers

What is plastic optical fiber? Plastic Optical Fiber (POF) is definitely an optical fiber which is made out of plastic. Because the late 1990s however, much higher-performance POF based on per fluorinated polymers has begun to appear available on the market. Plastic optical fibers are popular Nowadays.

Fiber technology is constantly on the become more flexible and less expensive. Plastic fiber optic cables are made from just one acrylic monofilament and are most efficient when used with visible red status indicator light sources. Plastic fibers are generally more cost effective than glass fiber optic cables and therefore are well suited for applications that need continuous flexing of the fiber. A wide range of fiber optic tips can be found.

In contrast, plastic optical fibers use harmless green or red light that is easily visible towards the eye. They may be safely installed in a house without risk to inquisitive children. A second advantage is their toughness. Plastic optical fibers tend to be thicker than glass optical fibers, a millimeter or more, and could be handled without special tools or techniques. You don’t have to be trained to handle and do the installation. You simply work with scissors, hook it up and it works.

In large-diameter optical fibers, 96% from the cross section is the core that enables the transmission of sunshine. Much like traditional glass optical fiber, POF transmits light with the core of the fiber. The core size POF is in some cases 100 times bigger than glass optical fiber.

POF has been called the consumer optical fiber since the fiber and associated optical links, connectors, and installation are all inexpensive. The per fluorinated polymer fibers are generally employed for much higher-speed applications for example data center wiring and building LAN wiring. POF, using its large core, continues to be likely to function as the office and residential network media. Its large core permits the utilization of cheap injection-molded plastic connectors which can significantly lower the total link cost. But POF features its own problems. The most crucial obstacle is its high signal loss (attenuation). PMMA has been used because the light guiding core for commercially accessible step-index POF and PMMA’s attenuation is about 100 dB/km. This high attenuation significantly limits POF’s applications in data communication applying a lot more than 100m.

Here is the good news though. Developers have discovered that PF amorphous polymer based gradient-index plastic optical fibers get rid of the attenuation problem with PMMA based plastic fiber. They’ve developed PF-polymer based Gradient-Index (GI) POF with attenuation level of only 10 dB/km. According to theoretical calculation, PF-polymer based GI POF can achieve similar degree of attenuation as silica-based glass fiber of 0.3dB/km.

Having a optimized refractive-index profile within the PF-polymer based GI POF, a lot more than 10Gb/s data transmission speed can be achieved over 1km. This is the metrics of PF-polymer’s low intrinsic loss and low material dispersion. Coupled with this theoretically possible high bandwidth and occasional total link cost, PF-Polymer based gradient-index plastic optical fiber includes a huge potential in fiber optic data communication applications.

With really small diameter, the POF cable is simple to run along skirting boards, under carpets and around tight corners. It offers additional durability for uses in data communications, as well as decoration, illumination and industrial application. FiberStore can supply both simplex and duplex plastic optical fibers. Our standard color is black. Other colors are available upon request.

Development and Application of Plastic Optical Fiber

Development and Application of Plastic Optical Fiber

The plastic optical fiber (POF) constituts that the optical fiber core and cladding are made of plastic material. Compared with large core diameter 50/125um and 62.5/125um quartz glass multimode fiber, plastic optical fiber core diameter is up to 200-1000um, while continuing to use without the optical fiber positioning sleeve cheap injection-molded plastic connector, even The fiber splice SMIC alignment generated the ± 30um deviation does not affect the coupling loss. It is plastic optical fiber structure gives the quick construction, connecting and low cost. In addition, the core diameter of 100um or larger and it is possible to eliminate noise in the the mold presence of the multimode fiber of quartz glass.

In recent years, Europe and Japan and other countries made important progress in the development of POF fiber. The development of plastic optical fiber, optical loss rate has dropped from 25 to 9 dB/km. Its wavelength has been extended to 870 microns (near infrared light), close to the practical level of the quartz glass fiber. United States developed a the PFX plastic series fiber has excellent anti-radiation performance. In addition, Boston, Massachusetts, fiber developed the Opti-Giga plastic optical fiber is compelling, it is not only lighter than glass, flexible better, lower cost, and data transmission speed of 3 megabits per second in the 100 meters . Such a fiber can also use the refraction of light or optical fibers within the jump way to achieve a higher transmission speed. Now the United States and Europe has plastic optical fiber used for short-distance transmission, such as automotive, medical equipment, copiers.

Japan attaches great importance to the application of plastic optical fiber, several years ago, NEC, Fujitsu, Sumitomo Electric Industries, Inc. 45 optical communications, multimedia products manufacturers jointly announced, will work together to achieve the plastic optical fiber have been successfully developed in Japan practical use. Plastic optical fiber production, Japan is also the world’s largest producers of plastic optical fiber, however, in Europe to promote the development of new applications of plastic optical fiber and fiber inspection standards. The second half of 2001, the European plastic optical fiber industrial development stage, this time to establish a new approach to development of the European plastic optical fiber test and measurement. The world’s first dedicated Plastic Optical Fiber Application Center (POFAC) in Nuremberg, Germany completed. Germany using plastic optical fiber has been developed multimedia bus system MOST (24Mbit/s), and several car manufacturers, the system has been incorporated into their products. BMW has created a record 100m plastic optical fiber in the new 7 series. Europe 2001 plastic fiber Symposium and European Fiber Communication Conference held in Amsterdam, the Netherlands. German automotive industry not only to promote the application of plastic optical fiber, but also contributed to the establishment of the plastic optical fiber test and measurement standards.

Japan has also established a plastic optical fiber standards, but these standards to the European Community is invalid. Japanese Industrial Standards is given only for the standard of a new type of plastic optical fiber, a numerical aperture of 0.5, and only the 650nm wavelength. The standard does not mention the different excitation light conditions in the plastic optical fiber, there is no provision must be formed in the plastic optical fiber equilibrium mode distribution.

Plastic optical fiber, compared with the glass fiber, although the light-transmitting differential, light loss is large, the initial ships of 300 dB/km, the transmission optical narrow band (limited to the visible region), is that it is difficult to adapt to the needs of the multimedia communication network, but it has light and soft, flexural, impact strength, cheap, anti-radiation, easy to process and can be made (1 to 3 mm in diameter, in order to increase the light-angle, expand the scope of) a series of advantages, so favored. In addition, the light passes through the central portion of the plastic optical fiber diameter of about 1 mm, about 100 times larger than the glass fiber, and the connection between the fiber connection and personal computer terminal apparatus is very easy. Plastic optical fiber installation costs low, very simple installation can align the connector plug, this plug can be used existing technology to produce.

The plastic optical fiber as the ideal short-range communication network transmission medium, in the future family of intelligent, office automation, industrial control network.
