The Evolution Of Optical Networks

The internet has revolutionized the modern world like no other invention has before, except perhaps, electricity. The internet allows sharing and collaboration to take place between people on opposite sides of the globe. Vinton G. Cerf, often called the “Father of the Internet”, admits that when the original idea of an “intranet” was in its infancy, there was no possible way to imagine all of the ways we would come to use it (NDTV, 2013).

• “IP (the Internet Protocol) is the most common Network Layer protocol where routing occurs” (Network Design, 2012). I will put in place two wireless network interfaces, which will interconnect with the newly installed fiber optic routing system. Internet nodes will communicate via the IP address, 172.15.100.10.

Measures for information transmission on fiber optic lines-can stretch out in reach up to 124 miles.

Coaxial cable uses a single conductor in the middle of a cable and the central conductor is surrounded by an insulator which is called the dielectric. Coax cables have become obsolete. Unshielded twisted pair cabling, also known as UTP cabling, has become the most common used network cabling. UTP cabling consists of four twisted pairs of wire, which have a different number of twists per foot, all encased on one sheath. This cabling is graded by different categories. Category 5 is recommended for Ethernet speeds of 100 Mbps. Category 5e, for running gigabit Ethernet or 1000BaseT networks. Category 6 and Category 6a are used to give better performance at higher speeds. Fiber optic cable is wave guided or light guided because it guides the light waves along the length of the cable. Single mode fiber optic cable can operate over long distances. Because fiber allows one mode of light to propagate, light pulses put on the fiber keep their shape much longer. This allows the light pulses to travel much further without interfering with other

4. TRANSPORT (layer 4) – provides transparent transfer of data between end systems, or hosts, and is responsible for end-to-end error recovery and flow control.

In order to provide a network infrastructure to over 600 users on the TaxiPixi network infrastructure, Fiber optic cabling system will be implemented in the LAN design because it is one of the best transmission media options.

layer 1 | Receive electrical signal over the network cable at X voltage, and X Mbps. |

The purpose of this paper is to provide a better understanding of switching and routing used in a network environment and familiarize the reader with various hardware and software associated with there functions. This paper will look at some switching concepts that will include store and forward switching, cut through switching, fragment free switching, and V-Lan. This paper will also cover routing concepts, along with some comparisons including routed vs. routing protocols, Classful vs. classless protocols, and distance vector vs. link state protocols.

With all the music and celebrity sightings, it's no wonder the event sells out so quickly. In order to get your tickets quickly, it's helpful to have a speedy internet service. Out of all the internet providers West Palm Beach, fiber optic internet is the fastest. Fiber optic internet West Palm Beach uses glass-fiber cables and light to quickly transport the internet service into your devices. Even though this connection for high speed internet West Palm Beach is extremely fast, it's also known to be the most expensive. However, those who love the service continue to call it the internet of the future. Though it's not easily accessible yet, it's only a matter of time before this form of broadband internet West Palm Beach takes

It just doesn't get much simpler than the physical bus topology when it comes to connecting nodes on a Local Area Network (LAN). The most common implementation of a linear bus topology is IEEE 802.3 Ethernet. All devices in a bus topology are connected to a single cable called the bus, backbone, or ether. The transmission medium has a physical beginning and an end. All connections must be terminated with a resistor to keep data transmissions from being mistaken as network traffic. The terminating resistor must match the impedance of the cable.

Topology: The current network was able to mix different speeds to match departmental needs. The physical topology in use is linear bus topology which also translates to a logical bus topology. The cable in use being Thicknet gives extended length allowance which is 500meters for a given segment and 2500 meters total cable

The physical layer specifics the function details for initiating, keeping up and turning off the physical link when moving the bits of data over the physical media such as copper, fibre or wireless. So it will takes your data bits of ones and zeros covert them to what is needed to transfer over that type of media so for example change bits into electrical signals for copper cables then will covert it back to ones and zeros once it reaches its destination to send up OSI model layers.

One of the most interesting developments in recent years in the field of telecommunication is the use of laser light to carry information over large distances. It has been proved in

Light enters one end of the fiber from a light bulb, laser, or some other source, and travels essentially unimpeded all the way to the length of the fiber where it is intercepted by a photosensitive detector such as an electronic device or even the human eye. The distance of travel varies according to the use to anywhere from just a few inches to over one-hundred and fifty miles. Fiber optic cable can transmit large amounts of information over one-hundred and fifty miles almost instantaneously. “While it takes five hours to transmit the contents of an encyclopedia over copper wires, the entire work can be transmitted in less than a minute over fiber optics” (Yawn PG).
