Nt1310 week3 Application: The transmission method of which is supported by telecom cabling such as 100Base-TX Ethernet or digital voice. Dark Fiber: A fiber carrying no light‚ it is common when extra fiber capacity is installed Plenum: The air handling space between walls‚ under structural floors‚ and above drop ceilings when used to circulate and otherwise handle air in a building. Riser: A space for indoor cables that allow cables to pass between floors‚ normally a vertical shaft

NT 1310 NETWORK TOPOLOGY PAPER: KENDAL JEFFERSON Network topology refers to layout of a network and how different nodes in a network are connected to each other and how they communicate. Mesh Topology: in a mesh network‚ devices are connected with many redundant interconnections between network nodes‚ in a true mesh topology every node has a connection to every other node in the network. There are two types of mesh topologies: Full mesh occurs when every node has a circuit connection it to every

NT 1310 PHYSICAL NETWORKING UNIT 7 DEFINITIONS KENDAL JEFFERSON 1. CROSSTALK: The coupling or transfer of unwanted signals from one pair within a cable to another pair. Crosstalk can be measured at the same (near) end or far end with respect to the signal source. Crosstalk is considered noise or interference and is expressed in decibels. 2. WAVEGUIDES: A structure that guides electromagnetic waves along their length. The core fiber in an optical-fiber cable is an optical waveguide. 3. FTTH: :

Ghattas The differences between LED and Laser Transmitters LED LED (Light-Emitting Diode) is a two-lead semiconductor light source. It resembles a basic p-n junction diode (is a boundary or interface between two types of semiconductor material‚ p-type and n-type‚ inside a single crystal of semiconductor.‚ which emits light when activated.

1) Describe a local land line phone system based on the following Landline Telephone Components: a. Local Loop: A wired connection from a telephone company’s central office in a locality to its customers home or business. A pair of coper wires called twisted pair is usually the connection. b. Central Office: An office responsible for providing certain services to a local loop with calls and signaling. c. Local Exchange: System of devices and or switches that direct the local calls. d. POP: Point

Unit 5. Lab. New Building-Wired and Wireless If I choose to design the new building with a wired network the main benefit is there would be a low chance on interception. Choosing a wired network will also have a lower risk of security issues; reliability and speed are primary benefits as well when using physical connections in a wired network. The basis of the new building will relay on loads of data to be moveable that is why a wired network allows the control. Wired LANs provide superior performance

The most critical part‚ the Cable and Fiber Preparation where the fiber is mounted‚ is the ferrule. The Ferrule is a long‚ thin cylinder with the fiber mounted in the center hole. The center hole is sized to match fiber’s cladding diameter which is usually 125um. When fiber connector ferrules are made from several types of materials including ceramic(Zirconia)‚ stainless steel and plastic. The ferrule’s job is to center and align the fiber and protects it from mechanical damage. The end of fiber

Local Exchange The online gaming industry has increased dramatically since technology’s capabilities have increased. The current protocol for online gaming is UDP because of less latency. If it were an FTP protocol it would have more latency because FTP headers are larger in size and the retransferring of files would populate the bandwidth too much and it would make the online gaming experience less enjoyable. Basically‚ the company who made the game has a server that all the players connect
