- How does the choice of cable and its length affect signal attenuation and data loss in high-speed data transmission, especially in the context of 10Gbps and 40Gbps networks?Que.a) Consider a CSMA/CD network that transmits data at a rate of 400 x 106 bits per second. The maximum signal propagation time from one node to another node is 20 microseconds. The minimum size of a frame in the network is(. bytes).Computer Science 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.
