...factors that could affect splicing performance: Cleaving is a major factor in splicing fiber optic cables, and it is necessary to use a good cleaver to do this with. Cleanliness is another factor that will affect splicing performance; the glass core must be cleaned prior to putting it in the connector because dust will play a factor in the performance of the splice. And using different brand of fiber cables can play a major factor in the overall performance of the splice. It can make it difficult to join the two cables together. The way to help reduce these factors is to ensure that you are using the proper splicing practices. (Fiber Optic Splicing) 3 intrinsic factors that can affect connection performance: Intrinsic factors are things that you cannot control during the splicing and connection process such as: Numerical Aperture mismatch, this is caused by the differences in the fiber itself and is nothing that you can control. Reflection loss is another factor that you cannot control because it is again based on the type of fiber optic cable you use for the splice. Refractive index profile distance is also a factor that is affects connection performance and it also caused by the cable manufacture and not something that you have done during the splicing process. The way to avoid all of this is to use the same type of fiber to do the splice if at all possible. (Intrinsic and Extrinsic factors) 3 extrinsic factors that affect connection performance: Extrinsic factors that you...

...fiber is most often used for its longer distance capability and higher bandwidth. TIA 568 specifies two multimode fibers, 62.5/125 (OM1) - the most common MM fiber until network speeds exceeded 1 Gb/s, and 50/125 (OM2 or OM3 - laser optimized) - a higher bandwidth fiber compatible with all fiber equipment. OM3 50/125 fiber is rated for use with lasers for >gigabit networks and is more often the choice now. Singlemode fiber is also specified for longer backbone links, as in a campus, for very high speed networks or where distance exceeds even OM3 fiber capability. Horizontal connections have traditionally been UTP copper, compatible the network port provideded on practically every type of computer gear. With the advent of wireless communications of adequate bandwidth and the inclusion of wireless adapters in all laptops and many other portable devices, wireless has become the user connection of choice. Virtually every corporate network now includes wireless, which is, of course, not wireless, since access points are connected into the network with copper or fiber cabling. Provision is necessary in the design of a facility for adequate numbers of access points, cabling to the access points and proper power, also conditioned and uninterruptible. Fiber optics is also a horizontal option in TIA 568, but not often used because of the higher cost of electronics. The exception is where high bitrate networks or future upgrades are expected. However, a properly designed...

...Unit 4 Assignment 1 Copper vs. Fiber Pape The two most common and widely used cabling types today for the means of communication all over the world are copper and fiber. They both do the same thing, transmit information from point A to point B but both have their strengths and weaknesses and therefore, a person installing cabling may be reluctant to choose one over the other. Copper cabling is less expensive to install. Copper wiring is flexible when installing so incase a technician has to bend it around a wall or at a certain angle to reach it to an end point, the cable can handle it. Also equipment to support copper wiring is relatively inexpensive to run. The weaknesses to copper wiring would be that it is susceptible to electromagnetic inference (EMI) from outside forces and also has a higher rate of corrosion over time by oxidation. Fiber optic cabling is a more expensive option for communications. Fiber optic cabling is immune to EMI and other noise interferences and therefore the chance of signal loss is greatly reduced. One drawback on this type of cabling is that just like its copper; fiber optic cabling is very durable and tough making it harder to work with when it comes to installing it. A technician will have to be very well trained in handling it to get the most out of it for the customer. But fiber optic cabling has a much higher bandwidth over copper so it can handle much more traffic as well as at higher speeds than copper wiring. In the real world, one...

...Authorship and Digital Media With the widespread adoption of personal computers, especially those connected to broadband Internet, the media landscape has changed drastically. All media-related industries, from newspaper to television to music and more, are experiencing this shift and are desperately attempting to react to the changing media landscape that has placed much of the control on the consumers rather than the producers of these media forms. Two digital media forms experiencing particularly interesting shifts of power are video games and digital music. Consumers of digital media forms such as video games and digital music files have complicated the traditional notion of authorship through their use of digital media technologies, which allows them to use digital media as an instrument of expression. Before delving into the intricacies surrounding this new form of authorship present in digital media it is first important to discuss the notion of authorship prior to the emergence of this digitally induced phenomenon. In non-digital mediums such as books, radio, and television, authorship exists as an individual endeavor, as authorship is only granted to the original author(s) of the media. As a consumer of this non-digital media the only point of contention as it relates to authorial expression is limited is the debate over authorial intent or narrative interpretation in these non-interactive cultural forms. Books, television, and radio are more or less consumed passively...

...1.2 shows the evolution of fiber optics communication in terms of devices used between terminal nodes and transition of fiber modes. After a period of research starting from 1975, the first commercial fiber-optic communications system was developed, which operated at a wavelength around 0.8 µm and used GaAs semiconductor lasers. This first-generation system operated at a bit rate of 45 Mbps with repeater spacing of up to 10 km. The second generation of fiber-optic communication was developed for commercial use in the early 1980s, operated at 1.3 µm, and used InGaAsP semiconductor lasers. These early systems were initially limited by multi mode fiber dispersion, and in 1981 the single-mode fiber was revealed to greatly improve system performance. By 1987, these systems were operating at bit rates of up to 1.7 Gb/s with repeater spacing up to 50 km. Third-generation fiber-optic systems operated at 1.55 µm and had losses of about 0.2 dB/km. This development was spurred by the discovery of Indium gallium arsenide and the development of the Indium Gallium Arsenide photodiode by Pearsall. Scientists overcame this difficulty by using dispersion-shifted fibers designed to have minimal dispersion at 1.55 µm. These developments eventually allowed third-generation systems to operate commercially at 2.5 Gbit/s with repeater spacing in excess of 100 km. The fourth generation of fiber-optic communication systems used optical amplification to reduce the need for repeaters and wavelength-division...
