b. Thin Fiber-Optic cable (8.3/125 microns)
c. Thick Fiber-Optic cable (62.5/125 microns)
d. Coaxial cable
Step by step
Solved in 2 steps
- Choose any two forms of transmission (twisted pairs, coaxial cable, microwave, satellite, fiber optical).. Which of the following is a characteristic of unshielded twisted-pair cabling? (Choose all that apply.) a. Consists of four wires b. Commonly used in physical bus topologies c. Has a distance limitation of 100 meters d. Susceptible to electrical interferenceWhat fiber is used in fiber-optic cabling to protect the inner core and prevent the cable from stretching?What fiber is used in fiber-optic cabling to protect the inner core and prevent the cable from stretching?
- If the signal at the end of a 6km cable has a power value of 2, if you knew that this cable loses 0.5 dB per km (i.e. -0.5 dB/km), then the power of the signal at the beginning of the cable was ..............For data is transmitted over twisted-pair cable, you have these characteristics: A signal's power on the channel is 60 dB, signal attenuation is 2 dB per 100 meters, and average noise power on the cable is 0.15 dB per meter. Answer the following questions: What's the S/N ratio at the end of a 60-meter channel? What's the S/N ratio at the end of a 1.5-kilometer channel? What's the maximum channel length if the receiving device requires at least 25 dB of S/N ratio for reliable operation?What is the propagation time if the distance between the two points is 48,900 ? Assume the propagation speed to be 2.4 x 108 meter/second in cable. a. 0.5 ms b. 20 ms c. 50 ms d. 200 ms
- 9.Fiber Optic Cable uses a. Electronic pulses to transmit Information down copper lines b. light pulses to transmit Information down fiber lines c. Does not send any pulses d. Requires a connector to send any pulsesUsing any two different forms of transmission as a comparison (twistted piars, coxial cable, microwave, satalitte, fibre optical).Calculate the length of cable through which a signal can be sent before its powerdecreases to half the original value. Do this for each of the media types aboveassuming that the attenuation in twisted pair cables is 6 dB/km, in coaxial cableis 1.5 dB/km and in optical fiber is 0.3 dB/km. Please show every step briefly.
