Copper vs. Fiber Copper and fiber wiring are the main mediums in which data is transferred across networks. Choosing between copper and fiber for the type of wiring is a large concern in the networking community. Understanding the strengths and weaknesses of each type helps to figure out which to use. There are many key factors to think of when making a choice such as, bandwidth, distance, and cost. As the name suggests, fiber optic technology uses pulses of light to carry data along strands of glass or plastic, which promises to deliver speeds of at least 100Mbps. When we're talking about 'speed' were actually talking about throughput (or capacity), the amount of data you can transfer per unit time. And fiber optics can definitely transfer more data at higher throughput over longer distances than copper wire. For example, a local area network using modern copper lines can carry 3000 telephone calls all at once, while a similar system using fiber optics can carry over 31,000. The key difference between the both is that fiber optic cables have much higher bandwidths than copper cables. Optical fiber can carry much higher frequency ranges, note that light is a very high frequency signal, while copper wire attenuates or loses signal strength at higher frequencies. Also, fiber optic technology is far less susceptible to noise and electromagnetic interference than electricity along a copper wire. You can send the signal for over 200 kilometers without any real

Copper cabling is the cheaper of the two wiring solutions. Copper cabling uses a copper wire to transmit data via electrical signals between connections. Copper cabling comes in a few different types of cable. Unshielded-twisted pair is most commonly used for horizontal cables. These cables are cheap and the network interface cards are cheap as well compared to Fiber NIC cards. In that sense UTP cables are most preferred for patch panels and computer connections to the network. They are also the…

1. In what ways was the planning and scope management for this project appropriate and when did they began taking unknowing or unnecessary risks? The project planning was to some extent appropriate. The design, while pushing beyond the boundaries of engineering practice, fully met the requirements of accepted theory at the time. The bridge’s design would have been sufficient if moderate winds did not occur since it had passed the static test. However, In addition to the mechanical causes that contributed…
