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

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.

Small Talk About Glass And Plastic Optical Fiber

Small Talk About Glass And Plastic Optical Fiber

Optical fiber is a flexible and transparent fiber made of glass or plastic that transmits light between the two ends of the fiber. Generally used in fiber optic communications, which permit transmissions over longer distances and at higher bandwidths, optical fibers provide better services compared to other forms of communication.

Nowadays, fiber optic cables are gaining in popularity, rapidly replacing traditional copper transmission cables. Instead of transmitting signals with electrical impulses like copper lines, fiber optic cables use light pulses that propagate through small strands of silica glass. To send data, a light source such as an LED or a laser is placed at one end of the cable. Copper wires are delicate and difficult to maintain, while fiber optic cables are durable, have stronger tension and are cheaper. Fiber cabling is not only required by large business corporations but also at home for smoother communication.

The most commonly used fiber optic cables are single mode, multimode and plastic optical fiber (POF). Multimode fibers are used for short-distance communication links and for applications where high power must be transmitted, while single-mode fibers are used for most communication links over one kilometer. Both single-mode and multimode fiber optic cables are made out of glass.

In contrast with glass fiber, plastic fibers use harmless green or red light that is easily visible to the eye. Plastic fibers can be safely installed in a home without risk to inquisitive children. A second advantage is their toughness. Plastic fibers are much thicker than glass fibers, a millimeter or more, and can be handled without special tools or techniques. You need not be trained to handle and install it. You just cut it with scissors, plug it in and it works.

POF is an optical fiber which is made out of plastic. Similar to traditional glass fiber, POF transmits light through the core of the fiber. But the core size of POF is in some cases 100 times larger than glass fiber. As fiber technology continues to become more flexible and less expensive, Plastic fibers are generally more cost effective than glass fiber optic cables and are ideal for applications that require continuous flexing of the fiber. POF cables are constructed of a single acrylic monofilament and are most efficient when used with visible red status indicator light sources. A wide range of fiber optic tips are available. POF has been called the consumer optical fiber because the fiber and associated optical links, connectors, and installation are all inexpensive. The per fluorinated polymer fibers are commonly used for much higher-speed applications such as data center wiring and building LAN wiring.

As a topping fiber optic cable supplier, Fiberstore offers high-quality products at an affordable price. Except the traditional single-mode and multimode glass fibers, we also supply figure of 8 cable and POF cable.

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.

How Much Do You Know About Plastic Optical Fibers?

How Much Do You Know About Plastic Optical Fibers?

Plastic optical fiber, or POF, has been overshadowed in the last decade by the success of glass optical fiber. As a result, POF had been relegated to low bit rate and short distance applications. Recent technological advances and the emergence of a killer application in the automotive industry have propelled POF into the limelight of a lower cost alternative to glass fiber or copper at medium distances and bit rates of 10 gbps. This paper reviews the history of POF , the technical developments that have created a buzz about POF, and the applications which are propelling POF into the mainstream. In addition, POF technology exhibits similar properties attributed to “Disruptive technologies”.

When people hear of optical fibers, they immediately think of glass. Few people, including professionals in the business, know about plastic optical fibers (POFs), which predate those made of glass. Because glass fibers have certain advantages, they have dominated the market, while POFs have remained largely in the background. Recent developments in technology and applications, however, have burnished the image of POFs, and they are finding a larger market with technology companies worldwide. Today, a new enthusiasm permeates the plastics side of optical fibers. The paper reviews the development if plastic optical fibers, emerging applications, and technological developments.

POFs compete with copper wires, coaxial cables, glass optical fibers, and wireless, and they require a transmitter, receiver, cables, and connectors similar to those used in glass optical-fiber links. Manufacturers form POFs out of plastic materials such as polystyrene, polycarbonates, and polymethyl methacrylate (PMMA). These materials have transmission windows in the visible range (520-780 nm).

However, the loss of light transmitted at these wavelengths is high, ranging from 150 dB/km for PMMA to 1,000 dB/km for polystyrene and polycarbonates. These losses often handicap plastic fibers in competing against high-quality glass fibers, which have losses of 0.2 dB/km for a single-mode fiber and less than 3 dB/km for multimode fibers. Hence, plastic fibers have been relegated to short-distance applications, typically of a few hundred meters or less, compared with the hundreds of kilometers for glass. Nonetheless, POFs have found many applications in areas such as industrial controls, automobiles, sensors for detecting high-energy particles, signs, illumination (including lighting works of art in museums), and short data links. Basically, POF applications divide into data-communication and non-data applications (sensors and signs, for example). Today, the surge in POF production stems from its use in data transmission.

What are the advantages of POF? Certain users find POF systems provide benefits compared to glass fiber or copper wire, which include:
• simpler and less expensive components
• lighter weight
• operation in the visible
• greater flexibility, and resiliency to bending, shock and vibration
• immunity to electromagnetic interference (EMI)
• ease in handling and connecting
• use of simple and inexpensive test equipment
• greater safety than glass fibers or fiber slivers that require a laser light source
• transceivers require less power than copper transceivers

Six common materials in fiber optic cable construction

Six common materials in fiber optic cable construction

There are mainly six common materials in fiber optic cable construction. Before you buy fiber optic cable, you should think about this. Here are the fiber optic cable materials with the introduction of their features and applications.

1. PVC (Polyvinyl Chloride)

Features:
1) Good resistance to environmental effects. Some formulations are rated for -55 to +55.
2) Good flame retardant properties. Can be used for both outdoor and indoor fiber optic cables.
3) PVC is less flexible than PE (Polyethylene) .

2. PE (Polyethylene)

Features:
1) Popular cable jacket material for outdoor fiber cables
2) Very good moisture and weather resistance properties
3) Very good insulator
4) Can be very stiff in colder temperatures
5) If treated with proper chemicals, PE can be flame retardant.

3. Fluoropolymers

Features:
1) Good flame-resistance properties
2) Low smoke properties
3) Good flexibility
4) Most often used for indoor fiber cables

4. Kevlar (Aramid Yarn)
Aramid yarn is the yellow fiber type material found inside cable jacket surrounding the fibers. It can also be used as central strength members.

Features:
1) Aramid yarn is very strong and is used in bundle to protect the fibers.
2) Kevlar is a brand of aramid yarn. Kevlar is often used as the central strength member on fiber cables which must withstand high pulling tension during installation.
3) When Kevlar is placed surrounding the entire cable interior, it provides additional protection for the fibers from the environment.

5. Steel Armor
Steel armor jacket is often used on direct burial outdoor cables and it provides excellent crush resistance and is truly rodent-proof. Since steel is a conductor, steel armored cables have to be properly grounded and loss fiber optic cable’s dielectric advantage.

Applications:
1) Outdoor direct burial cables
2) Fiber cables used for industrial environment where cables are installed without conduits or cable tray protection

Features:
1) Provides excellent crush resistance for outdoor direct burial cables
2) Protects cables from rodent biting
3) Decreases water ingress into the fiber which prolongs the fiber cable’s life expectancy

6. Central Strength Member
For large fiber count cables, a central strength member is often used. The central strength member provides strength and support to the cable. During fiber optic cable installation, pulling eyes should always be attached to the central strength member and never to the fibers. On fiber splice enclosure and patch panel installations, the cable central strength member should be attached to the strength member anchor on the enclosure or patch panel.
