d and e

d. The signal at the beginning of a cable with – 0.6 dB/km has a power of 11 mW. Calculate the power of the signal at 14 km. e. Calculate the total latency for a frame of size 1GB that are being sent on a link with 18 routers. Each router is having a queuing time of 11 µs and a processing time of 15 us. The length of the link is 20 000 Km. The speed of light inside the link is 2 x 108 m/s. The link has a bandwidth of 250 Mbps. Identify which component of the latency is dominant and which one is negligible.
