Uses of Fiber Optics Today Fiber optic technology has grown tremendously over the years and is used in many applications today. Without us realizing it, fiber optics are an essential part of our everyday lives. First Use of Fiber Optics One of the first uses of fiber optics was the telephone, and today, fiber optic technology has revolutionized long distance calls. It has also made wiretapping more difficult and helps to prevent electrical interference. Probably the biggest use today for fiber optics is the Internet, which is information that fiber optics cables send digitally. Fiber Optics and the Military Fiber optic technology is in high demand in the military today. The military has tested the cables rigorously and decided they were excellent to use in many of their applications. The fiber optic cables offer the military better performance, more bandwidth, and security for their signals - all at a lower cost. The cables are strong, lightweight, and can also be used outdoors in any type of harsh environment. These features make the fiber optic cables an excellent choice for use in the military’s retrieval and deployment applications. Fiber optic missile launchers and radar systems are also used in the military. In many of their control systems, the military uses a single optical fiber to replace miles and pounds of copper wire. Fiber Optics Used in our Transportation System The fast-paced transportation system is becoming a fast growing market for the use of fiber optics with the increase in traffic and more demand for automated toll booths, traffic signals, and message signs that are changeable. UAVs and Fiber Optics A fairly new and fast growing application for fiber optics is Unmanned Aerial Vehicles (UAVs). With the ability to provide a fast and efficient way to transmit a large amount of data over long distances, fiber optics were utilized as the main communication conduit between the UAV and ground control. Other Uses of Fiber Optics Fiber optics are also used in applications where bright light needs to be shone on a target without a clear line-of-sight path. They are also used to route sunlight from a roof to other parts of the building. Optical fiber illumination is used for decorative applications such as Christmas trees, signs, and art. Showcases displayed in boutiques use optical fibers for illumination of different angles with only one light source. Special optical fibers are used for sensor applications in areas that involve oil-well monitoring and fire or leak detection. The bandwidth offered by fiber optics enables cable television to transmit signals to their subscribers. This is very useful for the services cable companies offer. Other important fiber optic applications are used in research institutions, colleges and universities, aerospace, and chemical industries. Fiber optic technology is definitely growing rapidly and is an essential part of our everyday lives.
LAN (Local Area Network) and Fiber Optics Local Area Network (LAN) is a combined group of computers, or computer systems, connected to each other that allow shared program software or data bases. LAN systems are used by colleges, universities, office buildings, and industrial plants, for making use of optical fiber. LAN in Colleges and Universities With the technology of LAN and fiber optic applications, college students and professors can do their research from their rooms and offices without having to go to the library. It provides access to other campus colleges, enabling staff members to perform research with other college professors. It also enables students to take special courses from instructors at other colleges. College students in rural areas can now have quality-advanced curriculum without the high traveling expense. Purchasing software programs for a network will save the college a tremendous amount of money and also allows for easier upgrading. Colleges can also have passwords on their programs for denying access to unauthorized users. Using passwords, they do not have to worry about programs being illegally copied. Colleges or universities with a large number of students can add additional computers, scanners, and modems to the network for students to share. LAN provides dollar savings for students by allowing them to e-mail their friends at home and on other campuses instead of having to pay for a long distance phone bill. LAN and Office Buildings More and more companies today are demanding that fiber optic applications be made available when considering an office building as a rental place for their businesses. Some companies will even pay more to rent a building or office with fiber optic applications because they feel it is very important for their business to have access to a fast communication network. Companies that use fiber optic cables to set up their LAN do not have to worry with dangling and tangled cables, and their data is transmitted at an even higher quality and speed than with other network applications. With the fiber optic system, the company does not have to be concerned about a fire hazard because no electricity runs through the cables. Many very large office buildings use fiber optic lighting for their offices or for outdoor advertisements. LAN and Industrial Plants High-speed and high-quality communication links are needed in industrial plants. To monitor their processes online, industrial plants can use a fiber optic application to connect their control systems to their computer networks. A plant can also collect valuable information from other machines and plants that might help their plant’s machines run more smoothly and efficiently. Optical fibers have many physical properties that make them an excellent choice for the harsh environmental conditions found in industrial plants such as electromagnetic interference (EMI), extreme temperatures, and even lightning strikes. Fiber optic cables are rugged, have a very large bandwidth, have long cable lengths, and are immune to electromagnetic interference (EMI). By combining both LAN and fiber optic applications, colleges, universities, and businesses can obtain an almost endless stream of information on a daily basis. Companies can also use both of these to increase productivity while providing a convenient, safe environment for their employees and customers.
Fiber Optics in Our Work Environment Fiber optic technology has brought a whole new outlook for our fast-paced work environments. Fiber optic applications have helped to increase communication, profits, provide better medical benefits, and save time and money. Fiber Optics Role in Office Networks Office networks have found that fiber optics work very well as a backbone infrastructure. With fiber optic applications, office networks have high-capacity communication lines, which give them faster Internet connections, fax capabilities that are high-tech, and digital voice messaging. Networks use video conferencing instead of face-to-face meetings to bring clients together. This reduces the networks’ costs as well as the clients’ travel and expenses. Fiber optic applications allow office workers that must travel to be able to connect to the Internet and upload and download work orders and information faster than ever. With a fiber optic application, office networks have the advantage of sending more information at a time over their computers than before and using more phone lines without any disturbance. Fiber optic cables are the best types for computer networks because they send information digitally, and this is what the networks need. Large office networks also benefit from fiber optic applications because they can fit into tight spots and go around corners. This is due to the amazing flexibility of fiber optics. The security that fiber optic applications offer is a major benefit to firms such as banks, which are often owned by private networks. Fiber Optics in the Medical Field For many years, specialized fiber optic instruments have been used in the medical field. The lab and clinical diagnostics, endoscope, light therapy, x-ray imaging, dental hand pieces, surgical, and diagnostic instruments are some of the fiber optic applications. Fiber optic applications have helped the medical field advance tremendously over the past decade. They allow the physician to see inside specific areas of the body and perform surgery on hard-to-reach areas. Fiber optic applications also provide a quicker and more accurate analysis of blood work. They are also used for the removal of abnormal skin and cancerous growths. Patients benefit from medical fiber optic applications because they offer faster healing and less discomfort after surgical procedures due to smaller incisions. Fiber Optic Applications in other Work Environments Fiber optics are also helpful in many other fields today such as automotive, plumbing, electrical, engineering, carpentry, and exterminating. The automobile mechanic can check valves and pistons without removing the heads. The plumber can locate the cause of a blocked drain and pinpoint a leak easily. The engineer can see hard-to-reach places during safety inspections. All of this is due to fiber optic applications. Fiber Optic Comfort For businesses in need of a more pleasant work environment for their employees and customers, there is a fiber optic application available that brings sunlight in without using electricity. This would also result in great energy savings for the business. Future Fiber Optics As you can see, fiber optics are well-known not only in the network industry, but many others. With more and more demand, the fiber optic technology will continue to grow.
Understanding Fiber to the Premises (FTTP) Fiber to the Premises (FTTP) is a form of fiber optic communication delivery in which an optical fiber is run directly onto customers' premises. This new technology brings remarkable speed and an altogether new broadband experience. Fiber to the Premises uses fiber-optic cables and associated optical electronics instead of copper wire to connect a customer to a network. A central office distributes an optical signal over an optical distribution network (ODN). At the end of this network, optical network terminals (ONTs) will convert the optical signal into an electrical signal. The optical network terminals are located on private property for FTTP network architectures and the signal usually travels electrically between the ONT and the end-user’s device. Direct fiber and shared fiber are optical distribution networks with competing technology. Direct Fiber Direct fiber is the simplest optical distribution network since each fiber that leaves the central office only goes to one customer. Even though this network provides excellent bandwidth to the customer, the amount of fiber used and the central office machinery that is required is very costly. Because of this, the direct fiber is usually used close to a central office and in a small service area. Shared Fiber It is more common for each fiber leaving the central office to be shared by many customers. This fiber is split into individual customer-specific fibers when it gets close to the customers. This split is achieved by either an active optical network (AON) or a passive optical network (PON). Active Optical Network (AON) An active optical network (AON) uses equipment such as a router, switch, or multiplexer that is electrically powered to distribute a signal. Each signal that leaves the central office is directed only to the customer for whom it is intended. Passive Optical Network (PON) A passive optical network (PON) is a point-to-multipoint network with a high bandwidth that brings optical fiber cabling and signals all or most of the way to the end user by non-powered optical splitters, which means less cost, longer reach, and no upgrade. PONs rely on light waves and are capable of delivering high volumes of upstream and downstream bandwidth that can be changed to suit the user's needs. Included in a PON are an Optical Line Termination (OLT) at the service provider's central office and a number of Optical Network Units (ONUs) near end users. Advantages of FTTP With FTTP, new products and services can be activated remotely, either permanently or on demand, whichever the customer prefers. FTTP's performance can be monitored, and before the customer realizes there is a problem, it will be repaired. FTTP is easier to maintain and is less susceptible to harsh weather. With this new technology, FTTP brings remarkable speed and higher bandwidth along with a wide range of services at an affordable price for businesses and home owners.
Fiber Optics and Power Companies The technical direction a utility provider selects for its communications network will emulate its operating and business endeavors. The more complex and demanding the requirements are, the more likely a fiber-optic network will best serve its needs. Power Companies Gain Efficiency Power companies are beginning to apply fiber-optics in their communication systems now more than ever. Since their power lines already reach every telecommunications customer, they can compete more and save by teaming with the traditional phone company than with the networks built by new telecommunication startups. Many power utility companies have fiber-optic communication systems in place for supervising their power grid systems. Optical ground wire (OPT-GW) is one of the most common cable technologies used by power utilities. By using a fiber optic infrastructure, the utility company will increase its efficiency by networking operation centers, power-generating facilities, and substations. Customer Friendly Fiber Optics for Utility Customers A fiber optic infrastructure offers electric utility operations an upgraded internal communication network along with cost-efficient operation. These include customer friendly offerings such as remote meter reading and automatic billing. By interacting more with their customers, the utility company will find that customers will be more satisfied with the services and will show more loyalty. Advantages of Fiber Network Utility fiber networks are extremely useful to electric utility companies since they offer reliability. which is a major requirement in the industry. The fiber optic system offers high capacity with a feasible technical solution for easing excess capacity. Also offered is rapid upgrade, ease of deployment, and a versatile range of networks with a big advantage over other configurations. The advantage of being less susceptible to outages is very important to electric companies. This is offered with fiber optic cables because they are made with very strong material and are not susceptible to extreme weather conditions. By installing a fiber optic network, utility companies can have the security of lines no longer being dug up. They also don’t have to worry about access to lines by unauthorized personnel. Fiber Optic Networks are Economical Optical fiber is very economical for power utilities since they already own rights-of-way (ROW) and power poles. This gives the utility company the ability to install fiber optic cables alongside their existing power poles and increase their revenues for now and the future by leasing excess transmission capacity. The low cost of installing and operating with fiber optics provides utility companies a big savings since power utility personnel already have the qualifications for installing and working with cables. Future of Power and Fiber Optics With all of the opportunities offered to power companies today, they can improve their operations immensely and substantially increase their revenue because fiber optics is the evolution of the electric-power business.
Fiber Optics and Cable Television Cable television is one network system today that is making a drastic step forward by spreading out from its long established role as an entertainment service industry which includes on-demand video and broadcast television to a high-speed data service industry. The original design of cable television systems was the one-way, analog transmission system using coaxial cable. Today, cable television companies have found that fiber is the perfect choice for transmitting signals to multiple customer locations. In this distribution system, each location is connected to an isolated terminal by a dedicated optical fiber and the tuner connected with each individual customer TV set is stationed in the remote terminal. Channel-selection signals are sent over the fiber from the customer location to the remote terminal. The single selected channel is the only channel transmitted over the fiber from the remote terminal to the associated TV set. This application helps to prevent an outage for a large number of customers during a period of time and this in turn gives the cable companies a better customer relationship. It also helps to increase the company's revenue by giving them a return path in which they can use for telephone connections and Internet. Because of the growth in demand for communication signal transmission, cable television is in the midst of advancing their existing systems with fiber optic technology. Benefits to End Cable Users With fiber optic technology, cable companies can offer their customers a much better quality picture while at the same time reduce their operating costs because fiber optics cost much less to maintain. One of the main uses of fiber optics to cable companies is the large information carrying capacity, which is hundreds of times greater than copper wire. Fiber optics also offer essential protection from electrical interference and lightning. Fiber optics are highly reliable because they do not corrode in moisture, do not short out in water, and still perform at high speeds in any type of harsh weather. Optic cables are very lightweight because of their small size, and their long lengths make them easier to install. With fiber optic cables, there is no danger of fire hazards because they do not transfer any electricity. Signal Improvement Without losing power, fiber optic cables can carry television signals for a very long distance because of the technology of using very thin strands of glass. In different areas of the network, both single mode and multimode signals will be used. Signals will be sent from the central office to optical nodes using single mode fiber and then it will be converted to multimode. Optical cables use light signals instead of electricity and this makes the signals much clearer and offers a very low signal loss over a wide range frequency with no interference to other signals. Within the next few years, most cable television companies will have fiber optics installation, making it an advanced and versatile communications network solution.
