briefly explain the relationship between total reflection and fiber optic
A fiber optic cable is submerged underwater. What is the critical angle of total internal reflection if the index of refraction of the cable and water is n cable=2.15 and n water=1.33? options in degrees: 15.12, 42.79, 38.21, 61.33
Question 1 Select the correct statement(s) regarding fiber optic cable. a. The core and cladding within a fiber optic cable must have the same refractive index in order to achieve TIR (Total Internal Reflection) b. Only single mode fiber (SMF) can be constructed with either a “step” or “graded index” core c. Mulimode optical fibers (MMF) are vulnerable to modal dispersion d. All statements are correct Question 2 Using a direct sequence spread spectrum (DSSS) technique spreads a narrow band channel...
Distances between flaws in fiber-optic cable follow an exponential distribution with a mean of 30 meters. For a specific cable installation, you need to know the probability that the next flaw will occur between 20 and 40 meters from the current location.

How does fiber optic cabling protect your infrastructure?
Data is carried by pulses of light through long, transparent fibers—fiber optic cables. Long lengths of fiber carry signals 100 km between amplifier stations. How long does it take a signal to travel this distance if the index of refraction of the fiber is 1.45?
Problem 90. A) Does an optical fiber need a cladding for total internal reflection to occur? Justify your answer. B) Why do optical fibers have claddings? Problem 91. A) Estimate the width (duration of narrowest pulses that could be made with a laser source that outputs light over a frequency range from 5.0001 x 1014 Hz to 5.0002 x 1014 Hz. B) Consider an optical fiber of length 300 m. If a power of 4 mW is coupled into the...

QUESTION 4 Identify one major disadvantage of UTP media when compared to fiber optic media UTP cables are still more susceptible to electromagnetic interference than fiber optic cables, even though the pairs within the cable are twisted to help reduce interference and improve performance. UTP cables are more difficult to work with and require more specialized tools than fiber optic cables UTP cables are usually more expensive than fiber optic cables. UTP cables utilize a greater range of connectors, which...
