Fiber optics Essay

1.List the basic elements of a Fiber-Optic communion strategyA quality ocular transmission strand that female genitals carry the augur.A address of invisible infr atomic number 18d radiation modulated to impress digital data or an analog signal on the light beam.A sensitive sensing element to convert the optical signal back into an electrical signal at the receiver.Optical connectors at the light source-to- personal credit line interface and at the cable-to-photo detector interface.2.List Five advantages of an optical communications linkExtremely wide system bandwidth when comp atomic number 18d with other sources.Lower costs due to the fact that optical character costs continue to decline.Elimination of crosstalk because the light in angiotensin-converting enzyme glass fiber does not interfere with the light in an attached fiber. Optical communication links are not as unvaccinated to corrosion as other forms of data transmission links.An optical communication link muc kle be employ in the most in effect(p) environments due to its immunity from electromagnetic coupling and radiation.3.What are the commonly use wavelengths in fibre-optic systems? The three most commonly used wavelengths are 850 nm to 1310 nm, 1310 nm to 1550 nm, and 1600 nm to 1625 nm.4.A campus network is planning to rear fiber-optic cables to replace outdated coaxial cables. They have the choice of installing single-mode, multimode, or combination of single-multimode filer in the ground. Which fiber type should they select and wherefore? Both single-mode and multimode have their own advantages and disadvantages. Because of this, I would suggest that the campus network install a combination of single-mode and multimode. The use of the single-mode fiber can be used to run long distances across campus which is one of the greatest advantages of the single-mode fiber. Similarly, multimode fiber can be used at its best in short distances because it can carry higher bandwidth in sh orter distances than single-mode.5.The networking cables for a new building are being installed. You are asked to prepare a study about which cable type should be used. Discuss the issues related to the cable selection. In rule to keep up with the latest technological advances in computer networking, I would like to recommendthat you use fiber optic cable. Fiber optic cable provides substantially increased bandwidth and can handle the combined barter of PCs, switches, routers, video and voice services. Fiber optic cable has greater capacity enabling it to transfer data at faster speeds which in turn diminishes congestion problems, but also provides tremendous growth potency for each of the fiber runs.
