Compute the fraction of power transmitted as a function of the transmission-line loss in decibels. Dovl061 A this for a loss of 10, 40, 60, 80 and 100 dbs. AM2hovisson 19tugmonotofob bns Question # 2 01 # noite Two 1 km fibers are spliced together. Each fiber has a 10-dB loss and the splice adds 2-dB of loss. If the b916301 21 0211 Wis signs odi bnit 1915w Bill ni O QE 10 signs ns 16 dail power entering is 5 m W, then how much power is delivered to the end of this combined transmission line. (wal 2'lls stu-thiH) EEE I Question # 3 A receiver requires an input power of 50 n W. If the system losses add up to 100 dB, then how much power is required from the source? Question # 4 A fiber telephone cable contains 200 fibers, each capable of carrying 700 voice messages. A conducting telephone cable contains 1000 copper twisted pairs, and each can carry 25 messages. Compare the capacities of fiber and conducting cable. Question # 5 The 144-fiber telephone cable has a 12.7 radius. A 900- pair copper cable has a 70- mm diameter. Computer the ratio of cross-sectional area of these two transmission lines.
