NT 1310 Physical Networking Unit 9 Assignment 1 : Transmitters. Exercise 1 : Light Sources and Companents LAB 1 : New Building – Optical – Network Amir R. 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.

contains inorganic compounds. Paint tends to be inorganic in nature. The white‚ red‚ yellow pigments of paint is inorganic by nature. Organic compounds are based on carbon these are found only on living things. Inorganic is the opposite it doesnt come from living things its from synthetic fibers like polyester or nylon are carbon based but are not found in plants or animals. From a forensics science point of view both inorganic and organic compounds are very important when found in items of evidence

3. Should fiber optic horizontal cabling be installed but not terminated as future proofing for a future higher-speed network? What is the cost difference between copper UTP cable and fiber optic cable? Use this model to compute the relative cost—http://www.fols.org/cost_model. (10 points) Fiber optic cable is very expensive and is usually run on a WAN. If fiber optic cabling is already in use‚ I would leave the cable as it is‚ but if not‚ I wouldn’t recommend using it because fiber optic is very

Postganglionic Axon – Extends to the effector organ; nonmyelinated. 7. Acetylcholine (ACh) – All somatic motor neurons release this at their synapses with skeletal muscle fibers.; effects always stimulatory; preganglionic fibers release this as well. 8. Nonepinephrine (NE) – Autonomic postganglionic fibers release this by sympathetic fibers. 9. Dual Innervation – While one division stimulates certain smooth muscles to contract or a gland to secrete‚ the other division inhibits that action; all visceral

It can be metallic‚ nonmetallic‚ flexible‚ or rigid(depending upon local codes) and runs from a work area to a telecommunications room to the equipment room. One advantage of using conduit to hold the cables is that conduit may already exist in the building. A drawback to conduit is that it provides a finite amount of space

Guided Transmission media -some form of conductor that provide conduit in which signals are contained -the conductor directs the signal examples: copper wire‚ optical fiber Unguided Transmission media -wireless systems – without physical conductor -signals are radiated through air or vacuum -direction – depends on which direction the signal is emitted examples: air‚ free space Cable transmission media -guided

Proteins provide our bodies with the amino acids that cannot be produced within the body. Through the process of digestion‚ food is broken down into essential amino acids that can be used for protein synthesis. In essence‚ proteins build up‚ maintain‚ and replace tissues in your body. For instance‚ proteins help make hemoglobin which carries oxygen to all the parts of your body. Proteins are broken down into amino acids during digestion. The amino acids can then be reused when the body needs protein

mount and a long cylindrical ferrule to hold the fiber. Most ferrules are ceramic‚ but some are metal or plastic. And because they are spring-loaded‚ you have to make sure they are seated properly. If you have high loss‚ reconnect them to see if it makes a difference. 2. How should the existing and new campus locations be connected to each other?
